OSPFv3 commands

abr-summary (OSPFv3 area view)

Use abr-summary to configure route summarization on an ABR.

Use undo abr-summary to remove the configuration.

Syntax

abr-summary ipv6-address prefix-length [ not-advertise ] [ cost cost-value ]

undo abr-summary ipv6-address prefix-length

Default

Route summarization is not configured on an ABR.

Views

OSPFv3 area view

Predefined user roles

network-admin

Parameters

ipv6-address: Specifies the destination IPv6 address of the summary route.

prefix-length: Specifies the prefix length of the destination IPv6 address, in the range of 0 to 128. This argument specifies the number of consecutive 1s of the prefix, which defines the network ID.

not-advertise: Specifies not to advertise the summary IPv6 route. If you do not specify this keyword, the command advertises the IPv6 summary route.

cost cost-value: Specifies the cost of the summary route, in the range of 1 to 16777215. The default cost is the largest cost value among routes that are summarized.

Usage guidelines

This command applies only to an ABR to summarize multiple contiguous networks into one network.

To enable ABR to advertise specific routes that have been summarized, use the undo abr-summary command.

Examples

# Summarize networks 2000:1:1:1::/64 and 2000:1:1:2::/64 in Area 1 into 2000:1:1::/48.

<Sysname> system-view

[Sysname] ospfv3 1

[Sysname-ospfv3-1] area 1

[Sysname-ospfv3-1-area-0.0.0.1] abr-summary 2000:1:1:: 48

area

Use area to create an OSPFv3 area and enter OSPFv3 area view.

Use undo area to remove an OSPFv3 area.

Syntax

area area-id

undo area area-id

Default

No OSPFv3 areas exist.

Views

Predefined user roles

network-admin

Parameters

area-id: Specifies an area by its ID, an IPv4 address or a decimal integer in the range of 0 to 4294967295 that is translated into the IPv4 address format.

Examples

# Create OSPFv3 Area 0 and enter its view.

<Sysname> system-view

[Sysname] ospfv3 1

[Sysname-ospfv3-1] area 0

[Sysname-ospfv3-1-area-0.0.0.0]

asbr-summary (OSPFv3 view)

Use asbr-summary to configure route summarization on an ASBR.

Use undo asbr-summary to remove the configuration.

Syntax

asbr-summary ipv6-address prefix-length [ cost cost-value | not-advertise | nssa-only | tag tag ] *

undo asbr-summary ipv6-address prefix-length

Default

Route summarization is not configured on an ASBR.

Views

OSPFv3 view

Predefined user roles

network-admin

Parameters

ipv6-address: Specifies the destination IPv6 address of the summary route.

prefix-length: Specifies the prefix length in the range of 0 to 128.

cost cost-value: Specifies the cost of the summary route, in the range of 1 to 16777214. If you do not specify this option, the largest cost among the summarized routes applies. If the routes in Type-5 LSAs translated from Type-7 LSAs are Type-2 external routes, the largest cost among the summarized routes plus 1 applies.

not-advertise: Disables advertising the summary route. If you do not specify this keyword, the command advertises the route.

nssa-only: Limits the route advertisement to the NSSA area by setting the P-bit of Type-7 LSAs to 0. By default, the P-bit of Type-7 LSAs is set to 1. If the ASBR is also an ABR and FULL state neighbors exist in the backbone area, the P-bit of Type-7 LSAs originated by the ASBR is set to 0. This keyword applies to the NSSA ASBR.

tag tag: Specifies a tag for the summary route, in the range of 0 to 4294967295.

Usage guidelines

An ASBR can summarize routes in the following LSAs:

·     Type-5 LSAs.

·     Type-7 LSAs in an NSSA area.

·     Type-5 LSAs translated by the ASBR (also an ABR) from Type-7 LSAs in an NSSA area.

If the ASBR (ABR) is not a translator, it cannot summarize routes in Type-5 LSAs translated from Type-7 LSAs.

To enable ASBR to advertise specific routes that have been summarized, use the undo asbr-summary command.

Examples

# Configure a summary route 2000::/16, and specify a cost of 100 and a tag value of 2 for the summary route.

<Sysname> system-view

[Sysname] ospfv3 1

[Sysname-ospfv3-1] asbr-summary 2000:: 16 cost 100 tag 2

authentication-mode

Use authentication-mode to specify an authentication mode for an OSPFv3 area.

Use undo authentication-mode to restore the default.

Syntax

authentication-mode keychain keychain-name

undo authentication-mode

Default

No authentication is performed for an area.

Views

OSPFv3 area view

Predefined user roles

network-admin

Parameters

keychain: Specifies the keychain authentication mode.

keychain-name: Specifies a keychain by its name, a case-sensitive string of 1 to 63 characters.

Usage guidelines

The authentication mode specified for an OSPFv3 interface has a higher priority than the mode specified for an OSPFv3 area.

When keychain authentication is configured for an OSPFv3 area, OSPFv3 performs the following operations before sending a packet:

1.     Obtains a valid send key from the keychain.

OSPFv3 does not send the packet if it fails to obtain a valid send key.

2.     Uses the key ID, authentication algorithm, and key string to authenticate the packet.

If the key ID is greater than 65535, OSPFv3 does not send the packet.

When keychain authentication is configured for an OSPFv3 area, OSPFv3 performs the following operations after receiving a packet:

3.     Uses the key ID carried in the packet to obtain a valid accept key from the keychain.

OSPFv3 discards the packet if it fails to obtain a valid accept key.

4.     Uses the authentication algorithm and key string for the valid accept key to authenticate the packet.

If the authentication fails, OSPFv3 discards the packet.

OSPFv3 supports only the HMAC-SHA-256 authentication algorithms.

The ID of keys used for authentication can only be in the range of 0 to 65535.

Examples

# Configure OSPFv3 Area 1 to use keychain test for packet authentication.

<Sysname> system-view

[Sysname] ospfv3 1

[Sysname-ospfv3-1] area 1

[Sysname-ospfv3-1-area-0.0.0.1] authentication-mode keychain test

bandwidth-reference (OSPFv3 view)

Use bandwidth-reference to set a reference bandwidth value for link cost calculation.

Use undo bandwidth-reference to restore the default.

Syntax

bandwidth-reference value

undo bandwidth-reference

Default

The reference bandwidth value is 100 Mbps for link cost calculation.

Views

OSPFv3 view

Predefined user roles

network-admin

Parameters

value: Specifies the reference bandwidth value for link cost calculation, in the range of 1 to 4294967 Mbps.

Usage guidelines

You can configure an OSPFv3 cost for an interface with one of the following methods:

·     Configure the cost value in interface view.

·     Configure a bandwidth reference value. OSPFv3 computes the cost automatically based on the bandwidth reference value by using the following formula: Interface OSPFv3 cost = Bandwidth reference value / Interface bandwidth.

¡     If the calculated cost is greater than 65535, the value of 65535 is used.

¡     If the calculated cost is smaller than 1, the value of 1 is used.

If no cost value is configured for an interface, OSPFv3 computes the interface cost value automatically.

Examples

# Set the reference bandwidth value to 1000 Mbps.

<Sysname> system-view

[Sysname] ospfv3 1

[Sysname-ospfv3-1] bandwidth-reference 1000

default tag

Use default tag to set a tag for redistributed routes.

Use undo default tag to restore the default.

Syntax

default tag tag

undo default tag

Default

The tag of redistributed routes is 1.

Views

OSPFv3 view

Predefined user roles

network-admin

Parameters

tag: Specifies a tag for redistributed routes, in the range of 0 to 4294967295.

Usage guidelines

If you do not set a tag for redistributed routes by using the default-route-advertise, import-route, or route-tag command, the tag specified by the default tag command applies.

Examples

# Set the tag for redistributed routes to 2.

<Sysname> system-view

undo default-route-advertise

Default

No default route is redistributed into the OSPFv3 routing domain.

Views

OSPFv3 view

Predefined user roles

network-admin

Parameters

always: Redistributes a default route in an AS-external-LSA into the OSPFv3 routing domain regardless of whether a default route exists in the routing table. If you do not specify this keyword, the router redistributes a default route in an AS-external-LSA into the OSPFv3 routing domain only when the default route exists in the routing table.

permit-calculate-other: Enables OSPFv3 to calculate default routes received from other routers. If you do not specify this keyword, OSPFv3 does not calculate default routes from other routers. If the router does not redistribute any default route in an AS-external-LSA into the OSPFv3 routing domain, the router calculates default routes from other routers. It calculates these routes regardless of whether this keyword is specified.

cost cost-value: Specifies a cost for the default route, in the range of 0 to 16777214. The default is 1.

route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63 characters. When the routing policy is matched and one of the following conditions is met, the command redistributes a default route in an AS-external-LSA into the OSPFv3 routing domain:

·     A default route exists in the routing table.

·     The always keyword is specified.

The routing policy modifies values in the AS-external-LSA.

tag tag: Specifies a tag for the default route, in the range of 0 to 4294967295. If you do not specify this option, the tag specified by the default tag command applies.

type type: Specifies a type for the AS-external-LSA, 1 or 2. The default is 2.

Usage guidelines

This command redistributes a default route in an AS-external-LSA, which cannot be redistributed with the import-route command. If the local routing table has no default route, you must provide the always keyword for the command.

Examples

# Redistribute a default route into the OSPFv3 routing domain. (The default route does not exist in the local router.)

<Sysname> system-view

[Sysname] ospfv3 1

[Sysname-ospfv3-1] default-route-advertise always

Views

OSPFv3 view

Predefined user roles

network-admin

Parameters

ipv6-acl-number: Specifies an IPv6 ACL by its number in the range of 2000 to 3999 to filter redistributed routes by destination address.

prefix-list prefix-list-name: Specifies an IPv6 prefix list by its name, a case-sensitive string of 1 to 63 characters, to filter redistributed routes by destination address.

isisv6: Filters redistributed IPv6 IS-IS routes.

ospfv3: Filters redistributed OSPFv3 routes.

ripng: Filters redistributed RIPng routes.

process-id: Specifies a process by its ID in the range of 1 to 65535. The default value is 1.

static: Filters redistributed static routes.

Usage guidelines

To use an advanced ACL (with a number from 3000 to 3999) in the command, configure the ACL in one of the following ways:

·     To deny/permit a route with the specified destination, use rule [ rule-id ] { deny | permit } ipv6 source sour sour-prefix.

·     To deny/permit a route with the specified destination and prefix, use rule [ rule-id ] { deny | permit } ipv6 source sour sour-prefix destination dest dest-prefix.

The source keyword specifies the destination address of a route, and the destination keyword specifies the prefix of the route. For the configuration to take effect, specify a contiguous prefix.

Using the filter-policy export command filters only routes redistributed by the import-route command. If the import-route command is not configured to redistribute routes from other protocols and other OSPFv3 processes, the filter-policy export command does not take effect.

If you do not specify a routing protocol, the command filters all redistributed routes.

Examples

# Use IPv6 prefix list abc to filter redistributed routes.

<Sysname> system-view

[Sysname] ipv6 prefix-list abc permit 2002:1:: 64

[Sysname] ospfv3

[Sysname-ospfv3-1] filter-policy prefix-list abc export

# Configure IPv6 advanced ACL 3000 to permit only route 2001::1/128. Use ACL 3000 to filter redistributed routes.

<Sysname> system-view

[Sysname] acl ipv6 advanced 3000

[Sysname-acl-ipv6-adv-3000] rule 10 permit ipv6 source 2001::1 128 destination ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff 128

[Sysname-acl-ipv6-adv-3000] rule 100 deny ipv6

[Sysname-acl-ipv6-adv-3000] quit

[Sysname] ospfv3

[Sysname-ospfv3-1] filter-policy 3000 export

filter-policy import (OSPFv3 view)

Use filter-policy import to configure OSPFv3 to filter routes calculated using received LSAs.

Use undo filter-policy import to remove the configuration.

Syntax

filter-policy { ipv6-acl-number [ gateway prefix-list-name ] | prefix-list prefix-list-name [ gateway prefix-list-name ] | gateway prefix-list-name | route-policy route-policy-name } import

undo filter-policy import

Default

Routes calculated using received LSAs are not filtered.

Views

OSPFv3 view

Predefined user roles

network-admin

Parameters

ipv6-acl-number: Specifies an IPv6 ACL by its number in the range of 2000 to 3999 to filter routes by destination.

gateway prefix-list-name: Specifies an IPv6 prefix list by its name, a case-sensitive string of 1 to 63 characters, to filter routes by next hop. If you do not specify this option, the command does not filter routes by next hop.

prefix-list prefix-list-name: Specifies an IPv6 prefix list by its name, a case-sensitive string of 1 to 63 characters, to filter routes by destination.

route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63 characters, to filter received routes.

Usage guidelines

To use an advanced ACL (with a number from 3000 to 3999) in the command, configure the ACL in one of the following ways:

·     To deny/permit a route with the specified destination, use rule [ rule-id ] { deny | permit } ipv6 source sour sour-prefix.

·     To deny/permit a route with the specified destination and prefix, use rule [ rule-id ] { deny | permit } ipv6 source sour sour-prefix destination dest dest-prefix.

The source keyword specifies the destination address of a route, and the destination keyword specifies the prefix of the route. For the configuration to take effect, specify a contiguous prefix.

Using the filter-policy import command filters only routes computed by OSPFv3. Routes that fail to pass the filter are not added to the routing table.

Examples

# Use IPv6 prefix list abc to filter received routes.

<Sysname> system-view

[Sysname] ipv6 prefix-list abc permit 2002:1:: 64

[Sysname] ospfv3

[Sysname-ospfv3-1] filter-policy prefix-list abc import

# Configure IPv6 advanced ACL 3000 to permit only route 2001::1/128 to pass. Use ACL 3000 to filter received routes.

A GR process fails if a GR helper fails (for example, the interface connected to the GR helper goes down). If you do not specify this keyword, the command enables partial GR. In partial GR mode, a GR process can be completed as long as one GR helper exists.

planned-only: Enables planned GR only. If you do not specify this keyword, the command enables both planned GR and unplanned GR.

Usage guidelines

GR includes planned GR and unplanned GR.

·     Planned GR—Manually restarts OSPFv3 or performs an active/standby switchover. Before OSPFv3 restart or active/standby switchover, the GR restarter sends Grace-LSAs to GR helpers.

·     Unplanned GR—OSPFv3 restarts or an active/standby switchover occurs because of device failure. Before OSPFv3 restart or active/standby switchover, the GR restarter does not send Grace-LSAs to GR helpers.

OSPFv3 GR and OSPFv3 NSR are mutually exclusive. Do not configure the graceful-restart enable command and the non-stop-routing command at the same time.

To prevent service interruption after a master/backup switchover, a GR restarter running OSPFv3 must perform the following tasks:

·     Keep the GR restarter forwarding entries stable during reboot.

·     Establish all adjacencies and obtain complete topology information after reboot.

Parameters

planned-only: Enables only planned GR for the GR helper. If you do not specify this keyword, the command enables both planned GR and unplanned GR for the GR helper.

Usage guidelines

Upon receiving the Grace-LSA, the neighbors with the GR helper capability enter the helper mode (and are called GR helpers). Then, the GR restarter retrieves its adjacencies and LSDB with the help of the GR helpers.

Examples

# Enable the GR helper capability for OSPFv3 process 1.

Parameters

bgp4+: Redistributes IPv6 BGP routes.

direct: Redistributes direct routes.

static: Redistributes static routes.

isisv6: Redistributes IPv6 IS-IS routes.

ospfv3: Redistributes OSPFv3 routes.

ripng: Redistributes RIPng routes.

as-number: Redistributes routes from an AS specified by its number in the range of 1 to 4294967295. If you do not specify this argument, this command redistributes all IPv6 EBGP routes. As a best practice, specify an AS number to prevent the system from redistributing excessive IPv6 EBGP routes.

process-id: Specifies the process ID of a routing protocol, in the range of 1 to 65536. The default is 1.

all-processes: Redistributes routes from all the processes of the specified routing protocol.

allow-ibgp: Redistributes IBGP routes. The import-route bgp4+ command redistributes only EBGP routes. The import-route bgp4+ allow-ibgp command redistributes both EBGP and IBGP routes, and might cause routing loops. Therefore, use it with caution.

allow-direct: Redistributes the networks of the local interfaces enabled with the specified routing protocol. If you do not specify this keyword, the networks of the local interfaces are not redistributed. If you specify both the allow-direct keyword and the route-policy route-policy-name option, make sure the if-match rule defined in the routing policy does not conflict with the allow-direct keyword. For example, if you specify the allow-direct keyword, do not configure the if-match route-type rule for the routing policy. Otherwise, the allow-direct keyword does not take effect.

cost cost-value: Specifies a cost for redistributed routes, in the range of 1 to 16777214.

inherit-cost: Specifies to use the original cost of redistributed routes.

nssa-only: Limits the route advertisement to the NSSA area by setting the P-bit of Type-7 LSAs to 0. If you do not specify this keyword, the P-bit of Type-7 LSAs is set to 1. If the router acts as both an ASBR and an ABR and FULL state neighbors exist in the backbone area, the P-bit of Type-7 LSAs originated by the router is set to 0. This keyword applies to NSSA routers.

route-policy route-policy-name: Specifies a routing policy to filter redistributed routes. The route-policy-name argument is a case-sensitive string of 1 to 63 characters.

tag tag: Specifies a tag for external LSAs, in the range of 0 to 4294967295. If you do not specify this option, the tag specified by the default tag command applies.

type type: Specifies the type for redistributed routes, 1 or 2. The default is 2.

Usage guidelines

An external route is a route to a destination outside the OSPFv3 AS. External routes include the following types:

·     Type-1 external routes—Have high credibility. The cost of Type-1 external routes is comparable with the cost of OSPFv3 internal routes. The cost of a Type-1 external route equals the cost from the router to the ASBR plus the cost from the ASBR to the external route's destination.

·     Type-2 external routes—Have low credibility. OSPFv3 considers the cost from the ASBR to a Type-2 external route is much bigger than the cost from the ASBR to an OSPFv3 internal router. The cost of a Type-2 external route equals the cost from the ASBR to the Type-2 external route's destination.

The import-route command cannot redistribute default routes.

If you do not specify the cost or inherit-cost keyword, the cost for redistributed routes is 1.

The import-route nssa-only command redistributes AS-external routes in Type-7 LSAs only into the NSSA area.

Examples

# Configure OSPFv3 process 1 to redistribute routes from RIPng and specify the type as type 2 and cost as 50.

<Sysname> system-view

[Sysname] ospfv3

[Sysname-ospfv3-1] import-route ripng 10 type 2 cost 50

network-admin

Parameters

maximum-interval: Specifies the maximum OSPFv3 LSA generation interval in the range of 1 to 60 seconds.

minimum-interval: Specifies the minimum OSPFv3 LSA generation interval in the range of 10 to 60000 milliseconds. The default is 0, which indicates that the minimum interval can be any value.

incremental-interval: Specifies the OSPFv3 LSA generation incremental interval in the range of 10 to 60000 milliseconds.

Usage guidelines

When network changes are infrequent, LSAs are generated at the minimum interval. If network changes become frequent, the LSA generation interval is incremented by the incremental interval × 2n-2 for each generation until the maximum interval is reached. The value n is the number of generation times.

The minimum interval and the incremental interval cannot be greater than the maximum interval.

Parameters

default-route-advertise: Used on an NSSA ABR or an ASBR only. If it is configured on an NSSA ABR, the ABR redistributes a default route in a Type-7 LSA into the NSSA area. It redistributes a default route regardless of whether a default route exists in the routing table. If it is configured on an ASBR, the ASBR redistributes a default route in a Type-7 LSA only when the default route exists in the routing table.

cost cost-value: Specifies a cost for the default route, in the range of 0 to 16777214. If you do not specify this option, the default cost specified by the default-cost command applies.

nssa-only: Limits the default route advertisement to the NSSA area by setting the P-bit of Type-7 LSAs to 0. If you do not specify this keyword, the P-bit of Type-7 LSAs is set to 1. If the router acts as both an ASBR and an ABR and FULL state neighbors exist in the backbone area, the P-bit is set to 0.

route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63 characters. When the specified routing policy is matched, the command redistributes a default route in a Type-7 LSA into the OSPFv3 routing domain. The routing policy modifies values in the Type-7 LSA.

tag tag: Specifies a tag for the default route, in the range of 0 to 4294967295.

type type: Specifies a type for the Type-7 LSA, 1 or 2. The default is 2.

no-import-route: Used on an NSSA ABR to control the import-route command to not redistribute routes into the NSSA area.

no-summary: Used only on an ABR to advertise a default route in a Type-3 summary LSA into the NSSA area and to not advertise other summary LSAs into the area. The area is a totally NSSA area.

translate-always: Always translates Type-7 LSAs to Type-5 LSAs. This keyword takes effect only on an NSSA ABR.

translate-never: Never translates Type-7 LSAs to Type-5 LSAs. This keyword takes effect only on an NSSA ABR.

suppress-fa: Suppresses the forwarding address in the Type-7 LSAs from being placed in the Type-5 LSAs.

translator-stability-interval value: Specifies the stability interval of the translator. During the interval, the translator can maintain its translating capability after another device becomes the new translator. The value argument is the stability interval in the range of 0 to 900 seconds. The default interval is 0. A value of 0 means the translator does not maintain its translating capability when a new translator arises.

Usage guidelines

All routers attached to an NSSA area must be configured with the nssa command in area view.

Examples

# Configure Area 1 as an NSSA area.

Parameters

keychain: Specifies keychain authentication.

keychain-name: Specifies a keychain by its name, a case-sensitive string of 1 to 63 characters.

instance instance-id: Specifies an instance by its ID in the range of 0 to 255. The default is 0.

Usage guidelines

When keychain authentication is configured for an OSPFv3 interface, OSPFv3 performs the following operations before sending a packet:

1.     Obtains a valid send key from the keychain.

OSPFv3 does not send the packet if it fails to obtain a valid send key.

2.     Uses the key ID, authentication algorithm, and key string to authenticate the packet.

If the key ID is greater than 65535, OSPFv3 does not send the packet.

When keychain authentication is configured for an OSPFv3 interface, OSPFv3 performs the following operations after receiving a packet:

3.     Uses the key ID carried in the packet to obtain a valid accept key from the keychain.

OSPFv3 discards the packet if it fails to obtain a valid accept key.

4.     Uses the authentication algorithm and key string for the valid accept key to authenticate the packet.

If the authentication fails, OSPFv3 discards the packet.

OSPFv3 supports only the HMAC-SHA-256 authentication algorithm.

The ID of keys used for authentication can only be in the range of 0 to 65535.

network-admin

Parameters

broadcast: Specifies the network type as broadcast.

nbma: Specifies the network type as NBMA.

p2mp: Specifies the network type as P2MP.

unicast: Specifies the P2MP interface to unicast OSPFv3 packets. By default, a P2MP interface multicasts OSPFv3 packets.

p2p: Specifies the network type as P2P.

instance instance-id: Specifies an instance by its ID in the range of 0 to 255. The default is 0.

Usage guidelines

If a router on a broadcast network does not support multicast, configure the network type for the connected interfaces as NBMA.

When the network type of an interface is NBMA or P2MP unicast, you must use the peer command to specify the neighbor.

When the network type of an interface is P2MP unicast, all OSPFv3 packets are unicast by the interface.

cost cost-value: Specifies the cost of the neighbor, in the range of 1 to 65535.

dr-priority priority: Specifies the DR priority of the neighbor, in the range of 0 to 255. The default is 1.

instance instance-id: Specifies an instance by its ID in the range of 0 to 255. The default is 0.

Usage guidelines

For NBMA and P2MP interfaces (only when in unicast mode), you must specify the link-local IPv6 addresses of their neighbors because these interfaces cannot find neighbors through broadcasting hello packets. For NBMA interfaces, you can also specify DR priorities for their neighbors.

Examples

# On VLAN-interface 10, specify the link-local address of its neighbor as FE80::1111.

Parameters

seconds: Specifies the LSA retransmission interval in the range of 1 to 3600 seconds.

instance instance-id: Specifies an instance by its ID in the range of 0 to 255. The default is 0.

Usage guidelines

After the device sends an LSA to its neighbor, it waits for an acknowledgment. If the device receives no acknowledgment after the LSA retransmission interval elapses, it will retransmit the LSA.

To avoid unnecessary retransmissions, set an appropriate retransmission interval. For example, you can set a large retransmission interval value on a low-speed link.

Examples

# Set the LSA retransmission interval to 12 seconds on VLAN-interface10 in instance 1.

Views

OSPFv3 view

Predefined user roles

network-admin

Usage guidelines

By default, an OSPFv3 interface advertises all of its prefixes in LSAs. To speed up OSPFv3 convergence, you can suppress interfaces from advertising all of their prefixes. This feature helps improve network security by preventing IP routing to the suppressed networks.

To disable an OSPFv3 process from advertising the prefixes of loopback and passive interfaces, configure prefix suppression on the interfaces by using the ospfv3 prefix-suppression command.

When prefix suppression is enabled:

·     OSPFv3 does not advertise the prefixes of suppressed interfaces in Type-8 LSAs.

·     On broadcast and NBMA networks, the DR does not advertise the prefixes of suppressed interfaces in Type-9 LSAs that reference Type-2 LSAs.

·     On P2P and P2MP networks, OSPFv3 does not advertise the prefixes of suppressed interfaces in Type-9 LSAs that reference Type-1 LSAs.

Parameters

context-name: Specifies a context name, a case-sensitive string of 1 to 32 characters.

Usage guidelines

The standard OSPFv3 MIB provides only single-instance MIB objects. For SNMP to correctly identify OSPFv3 management information in the standard OSPFv3 MIB, you must configure a unique context name for OSPFv3. If multiple OSPFv3 processes exist, you must assign a unique context to each process.

Context is a method introduced to SNMPv3 for multiple-instance management. For SNMPv1/v2c, you must specify a community name as a context name for protocol identification.

Parameters

maximum-interval: Specifies the maximum OSPFv3 route calculation interval in the range of 1 to 60 seconds.

minimum-interval: Specifies the minimum OSPFv3 route calculation interval in the range of 10 to 60000 milliseconds.

incremental-interval: Specifies the incremental OSPFv3 route calculation interval in the range of 10 to 60000 milliseconds.

Usage guidelines

Based on the LSDB, an OSPFv3 router uses SPF to calculate a shortest path tree with itself being the root. OSPFv3 uses the shortest path tree to determine the next hop to a destination. By adjusting the SPF calculation interval, you can prevent overconsumption of bandwidth and router resources due to frequent topology changes.

For a stable network, the minimum interval is used. If network changes become frequent, the SPF calculation interval is incremented by the incremental interval × 2n-2 for each calculation until the maximum interval is reached. The value n is the number of calculation times.

The minimum interval and the incremental interval cannot be greater than the maximum interval.

Examples

# Set the maximum SPF calculation interval to 10 seconds, minimum interval to 500 milliseconds, and incremental interval to 300 milliseconds.

summary-lsa max-metric-value: Specifies a cost for Type-3 and Type-4 LSAs, in the range of 1 to 16777215. The default is 16711680.

include-stub: Specifies the cost for Type-9 LSAs that reference Type-1 LSAs to the maximum value 65535.

on-startup seconds: Specifies the router as a stub router during reboot, and specifies the timeout time in the range of 5 to 86400 seconds.

wait-for-bgp seconds: Specifies the router as a stub router during BGP route convergence after reboot, and specifies the timeout time in the range of 5 to 86400 seconds. The default timeout time is 600 seconds.

Usage guidelines

You can use the stub-router r-bit command or stub-router max-metric command to configure a router as a stub router.

·     The stub-router r-bit command clears the R-bit of the Option field in Type-1 LSAs. When the R-bit is clear, the OSPFv3 router can participate in OSPFv3 topology distribution without forwarding traffic.

·     The stub-router max-metric command specifies the OSPFv3 max-metric router LSA feature. This feature enables OSPFv3 to advertise its locally generated Type-1 LSAs with a maximum cost of 65535. Neighbors do not send packets to the stub router as long as they have a route with a smaller cost.

Parameters

router-id: Specifies the router ID of the neighbor on the virtual link.

dead seconds: Specifies the dead interval in the range of 1 to 32768 seconds. The default is 40. The dead interval must be identical with that on the virtual link neighbor, and must be a minimum of four times the hello interval.

hello seconds: Specifies the hello interval in the range of 1 to 8192 seconds. The default is 10. It must be identical with the hello interval on the virtual link neighbor.

instance instance-id: Specifies the instance ID of a virtual link, in the range of 0 to 255. The default is 0.

ipsec-profile profile-name: Specifies an IPsec profile by its name, a case-insensitive string of 1 to 63 characters. For more information about IPsec profiles, see Security Configuration Guide.

keychain: Specifies the keychain authentication mode.

keychain-name: Specifies a keychain by its name, a case-sensitive string of 1 to 63 characters.

retransmit seconds: Specifies the retransmission interval in the range of 1 to 3600 seconds. The default is 5.

trans-delay seconds: Specifies the transmission delay interval in the range of 1 to 3600 seconds. The default is 1.

Usage guidelines

You can configure a virtual link to maintain connectivity between a non-backbone area and the backbone, or maintain connectivity within the backbone. A virtual link is similar to an interface with OSPFv3 enabled. You can configure parameters such as hello, dead, retransmit and trans-delay for the virtual link.

Both ends of a virtual link must be ABRs that are configured with the vlink-peer command.

The following guidelines apply to parameters:

·     The smaller the hello interval is, the faster the network converges, and the more network resources are consumed.

·     For a low speed link, set a large retransmission interval to avoid unnecessary retransmissions.

·     Specify a transmission delay with the trans-delay keyword depending on the interface delay.

The authentication mode specified for an OSPFv3 virtual link has a higher priority than the mode specified for the backbone area. If no authentication mode is specified for the virtual link, the mode specified for the backbone area applies.

When keychain authentication is configured for an OSPFv3 virtual link, OSPFv3 performs the following operations before sending a packet:

1.     Obtains a valid send key from the keychain.

OSPFv3 does not send the packet if it fails to obtain a valid send key.

2.     Uses the key ID, authentication algorithm, and key string to authenticate the packet.

If the key ID is greater than 65535, OSPFv3 does not send the packet.

When keychain authentication is configured for an OSPFv3 virtual link, OSPFv3 performs the following operations after receiving a packet:

3.     Uses the key ID carried in the packet to obtain a valid accept key from the keychain.

OSPFv3 discards the packet if it fails to obtain a valid accept key.

4.     Uses the authentication algorithm and key string for the valid accept key to authenticate the packet.

If the authentication fails, OSPFv3 discards the packet.

OSPFv3 supports only the HMAC-SHA-256 authentication algorithm.

The ID of keys used for authentication can only be in the range of 0 to 65535.

Examples
