network-admin

Parameters

priority-color&<1-32>: Sets the Priority-Color extended community attribute, a string of 3 to 12 characters. &<1-32> indicates that you can specify a maximum of 32 Priority-Color extended community attributes. The value for the priority-color argument is in Priority:Site ID:Device ID or Priority:Site ID format:

· The priority value range is 0 to 15. A smaller priority value indicates a higher priority.

· The site ID range is 1 to 65535 and the device ID range is 1 to 255. You can specify an SDWAN device on the SDWAN network by its site ID and device ID.

additive: Adds the specified Priority-Color extended community attribute to the original Priority-Color extended community attribute of BGP routes. If you do not specify this keyword, the specified Priority-Color attribute replaces the original Priority-Color attribute of BGP routes.

Usage guidelines

The Priority-Color extended community attribute is used only in SDWAN-encapsulated EVPN routes. In an SDWAN network, you can add backup routes for an EVPN route by adding the Priority-Color extended community attribute. When the data channel fails, traffic can bypass the data channel.

If an IP prefix advertisement route does not contain a Priority-Color attribute, only one route can be added to the BGP-VPN instance routing table or the VPN instance IP routing table. The route's next hop is the next hop of the IP prefix advertisement route. If the next hop is not reachable, the IP prefix advertisement route fails, and thus traffic forwarding to the IP prefix fails.

If an IP prefix advertisement route contains Priority-Color attributes, the device can add one primary route and multiple backup routes to the BGP-VPN instance routing table as follows:

· If the Priority-Color attributes contain device IDs, the device generates a backup route based on each Priority-Color attribute.

· If the Priority-Color attributes do not contain device IDs, the device generates a backup route based on each SDWAN device in the site identified by the site ID in each Priority-Color attribute.

The primary and backup routes use the same prefix. When a backup route is added to the VPN instance IP routing table, the next hop is the system IP of the device identified by the site ID and device ID in the Priority-Color attribute.

When the primary route is reachable, the primary route is added to the VPN instance IP routing table. When the primary route fails, the optimal backup route is added to the VPN instance IP routing table. The optimal backup route is determined as follows:

1. The backup route with the highest priority is the optimal backup route. The priority of a backup route is determined by the priority value in the Priority-Color attribute that generated the backup route. A smaller priority value indicates a higher priority.

2. If multiple backup routes have the same priority, the backup route with the lowest next hop IP address is the optimal route.

In BGP-VPN IPv4 or IPv6 unicast address family, you can enable BGP load balancing by using the balance command. All optimal backup routes with the same priority are then added to the VPN instance IP routing table for load balancing, regardless of the primary route's state.

In BGP load balancing, the priority value of the primary route is regarded as 0. The primary route and the backup routes with priority value of 0 are all added to the VPN instance IP routing table for load balancing. When the primary route fails, the primary route does not participate in load balancing any longer. If no backup routes with priority value of 0 exist, only the primary route is added to the VPN instance IP routing table and no load balancing can be performed. After the primary route fails, all backup routes with the same, smallest priority value are added to the VPN instance IP routing table for load balancing.

For more information about BGP load balancing, see BGP configuration in Layer 3—IP Routing Configuration Guide.

When you specify a Priority-Color extended community attribute in Priority:Site ID:Device ID format, the attribute cannot take effect if it has the same site ID as an existing Priority-Color extended community attribute in Priority:Site ID format.

Parameters

site-of-origin&<1-32>: Sets the SoO extended community attribute, a string of 3 to 24 characters. &<1-32> indicates that you can specify a maximum of 32 SoO extended community attributes.

An SoO attribute has the following forms:

· 16-bit AS number:32-bit self-defined number, for example, 101:3. The AS number is in the range of 0 to 65535, and the self-defined number is in the range of 0 to 4294967295.

· 32-bit IP address:16-bit self-defined number, for example, 192.168.122.15:1. The self-defined number is in the range of 0 to 65535.

· 32-bit AS number:16-bit self-defined number, for example, 70000:3. The AS number is in the range of 65536 to 4294967295, and the self-defined number is in the range of 0 to 65535.

· 32-bit IP address/IPv4 address mask length:16-bit user-defined number, for example, 192.168.122.15/24:1.

· 32-bit AS number in dotted format:16-bit user-defined number, for example, 65535.65535:1.

Parameters

flex-algo-id: Specifies a flexible algorithm ID in the range of 128 to 255.

Usage guidelines

Application scenarios

Flexible algorithms enable users to define separate topologies for path calculation. They are mainly used in SR networks.

Restrictions and guidelines

NOTE:

In the current software version, f lexible algorithm ID configuration is supported only for redistributed IPv6 IS-IS and BGP routes.

‌

When you apply flexible algorithms to an SRv6 network, each flexible algorithm calculates routes independently. To redistribute the routes calculated in a flexible algorithm topology (topology k2) to another (topology k1), perform the following task:

1. Configure a routing policy that contains an apply flex-algo clause. The flexible algorithm ID specified in that apply clause is the flexible algorithm ID of topology k1.

2. Enter the IS-IS IPv6 unicast view of the edge nodes in topologies k1 and k2, and then specify the routing policy above in the import-route command to filter redistributed routes.

In this example, you need to configure route redistribution for the IS-IS process that participates in the route calculation of topology k1.

The task above can redistribute only the IPv6 IS-IS routes calculated by topology k2 to topology k1. The IPv6 IS-IS routes not calculated by flexible algorithm will not be redistributed. The algorithm ID range for a flexible algorithm route is 128 to 255. The algorithm ID of a non-flexible algorithm route is fixed at 0.

· The routing policy sets the algorithm ID of an IPv6 IS-IS route to the flexible algorithm ID of topology k1 if the following conditions exist:

¡ The route passes the routing policy specified in the import-route command.

¡ The algorithm ID of the route is in the range of 128 to 255.

· If the algorithm ID of an IPv6 IS-IS route is 0, the routing policy does not set the algorithm ID of the route to the flexible algorithm ID of topology k1. As a result, the route cannot be redistributed to topology k1.

When the edge node redistributes the IPv6 BGP routes of topology k2 to topology k1, the routing policy specified in the import-route command filters those routes. The routing policy will add the flexible algorithm ID of topology k1 to the IPv6 BGP routes that pass the routing policy.

For information about flexible algorithms, see IS-IS configuration in Layer 3—IP Routing Configuration Guide.

Parameters

mpls-exp-value: Specifies an MPLS EXP value in the range of 0 to 7.

Usage guidelines

MPLS determines the transmission priority of a packet based on the EXP value carried in its label. By default, an ingress node uses the IP preference of a packet as the EXP value in the MPLS label added to the packet.

Use this command to set an MPLS EXP value for routes on an ingress node. The routes will carry the EXP value when they are added to the FIB table. To enable the ingress node to encapsulate the specified EXP value in MPLS packets, you must also configure the ip forwarding apply mpls-exp enable command. For more information about the ip forwarding apply mpls-exp enable command, see IP forwarding basics commands in Layer 3—IP Services Command Reference.

Parameters

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

Usage guidelines

When you use a routing policy as the if-match clause criterion for another routing policy, the if-match clause works as follows:

· When the match mode of a node is deny, a route is rejected if the route meets all the if-match clauses of the node. The route is not compared with the next node. If the route does not meet all the if-match clauses of the node, it is compared with the next node.

· When the match mode of a node is permit, a route is handled by the apply clauses of the node if the route meets all the if-match clauses of the node. If the route does not meet all the if-match clauses of the node, it is compared with the next node.

Follow these restrictions and guidelines when you configure a routing policy if-match clause criterion:

· If the specified routing policy does not exist, all routes match the criterion.

· If a routing policy has been used as an if-match clause criterion, you cannot specify a routing policy match criterion for the routing policy. For example, if routing policy A uses routing policy B as a match criterion, you cannot specify any routing policy match criterion for routing policy B. In addition, you cannot specify routing policy A as a match criterion for any another routing policies.

· Reference loops are not allowed. For example, if routing policy A is used as a match criterion of routing policy B, you cannot configure routing policy B as a match criterion of routing policy A any more.

If you execute this command multiple times for a routing policy, the most recent configuration takes effect.

For more information about regular expressions, see Layer 3—IP Routing Configuration Guide.

Examples

# Configure AS path list 1 to permit routes whose AS_PATH attribute starts with 10.

not-match-priority: Ignores the Priority field of Priority-Color extended community attributes. If you specify this keyword, the specified extended community list matches against only the Site ID and Device ID fields of Priority-Color extended community attributes. If you do not specify this keyword, a route can match the specified extended community list only when its Priority-Color extended community attribute exactly matches the specified extended community list.

advanced regular-expression: Specifies a regular expression to filter Priority-Color extended community attributes. The value for the regular-expression argument is a string of 1 to 63 characters. If the Priority-Color extended community attribute of a route matches the specified regular expression, the route can match the specified extended community list.

Predefined user roles

network-admin

Parameters

rd-list-number: Specifies an RD list by its number in the range of 1 to 65535.

index index-number: Specifies an index number for an RD list item, in the range of 1 to 4294967295. An item with a smaller index number is matched first. If you do not specify this option, the index number starts from 10 and increases by 10 for each of the consecutive RD list items.

deny: Specifies the deny mode. If a route matches the item, the route is denied without being compared with the next item. If a route does not match the item, the route is compared with the next item.

permit: Specifies the permit mode. If a route matches the item, it passes the RD list. If a route does not match the item, the route is compared with the next item.

route-distinguisher&<1-10>: Specifies a list of up to 10 RD list items. Each item is a string of 3 to 21 characters.

An RD has the following forms:

· 16-bit AS number:32-bit self-defined number. For example, 101:3.

· 16-bit AS number:wildcard character. For example, 101:*.

· 32-bit IP address:16-bit self-defined number. For example, 192.168.122.15:1.

· 32-bit IP address:wildcard character. For example, 192.168.122.15:*.

· 32-bit AS number:16-bit self-defined number. For example, 65536:1. The minimum AS number is 65536.

· 32-bit AS number:wildcard character. For example, 65536:*. The minimum AS number is 65536.

Usage guidelines

An RD list matches the RDs of BGP routes. An RD list is identified by an RD list number and can contain multiple items that specify RD ranges. The relationship between the items is logical OR. A route matches the RD list if it matches one item in the list. A route does not match the RD list if it does not match any items in the list.

To filter routes by RD, use the ip rd-list command together with the if-match rd-list command. If you specify a nonexistent RD list for the if-match rd-list command, all routes pass the RD match criterion.

Examples

# Configure RD list 1 to permit routes with RD 100: 1.

<Sysname> system-view

[Sysname] ip rd-list 1 permit 100:1

Parameters

tag-list-number: Specifies a tag list by its number in the range of 1 to 65535.

index index-number: Specifies an index for the tag list entry, in the range of 1 to 4294967295. A tag list entry with a smaller index number is matched first. If you do not specify this option, the index number starts from 1 and increases by 1 for each of the consecutive tag list entries.

deny: Specifies the match mode for the tag list as deny.

permit: Specifies the match mode for the tag list as permit.

tag-value: Specifies a tag value in the range of 0 to 4294967295. &<1-32> indicates that the argument before it can be entered up to 32 times.

Usage guidelines

If you execute this command multiple times for a tag list entry, all tag values take effect. A tag list entry can contain up to 32 tag values.

Examples

Views

System view

Predefined user roles

network-admin

Parameters

route-policy-name: Specifies a routing policy name, a case-sensitive string of 1 to 63 characters.

deny: Specifies the deny match mode for the routing policy node. If a route matches all the if-match clauses of the node, it is denied without being compared with the next node. If a route does not match any if-match clauses of the node, the route is compared with the next node.

permit: Specifies the permit match mode for the routing policy node. If a route matches all the if-match clauses of the node, it is handled by the apply clauses of the node. If a route does not match any if-match clauses of the node, the route is compared with the next node.

node node-number: Specifies a node number in the range of 0 to 65535. A node with a smaller number is matched first.

Usage guidelines

Use a routing policy to filter routing information. A routing policy can contain several nodes and each node contains a set of if-match and apply clauses. The if-match clauses define the match criteria of the node and the apply clauses define the actions to be taken on packets matching the criteria. The relation between the if-match clauses of different types is logical AND and the relation between the if-match clauses of the same type is logical OR. if-match clauses of all types must be met. The relation between nodes is logical OR. A packet passing a node passes the routing policy. If a packet does not pass any nodes, the packet does not pass the routing policy.

Examples

# Create node 10 in permit mode for routing policy policy1 and enter routing policy node view.

Views

System view

Predefined user roles

network-admin

Parameters

time-value: Specifies the routing policy change delay timer in the range of 60 to 3600 seconds. When this delay timer expires, the routing protocol waits five seconds before processing routes from the new routing policy.

unlimited: Sets an infinite delay timer.

Usage guidelines

This command makes a routing policy take effect after a delayed time interval, which prevents incomplete routing policy configuration from being issued to cause incorrect route advertisement. The system automatically starts the timer when a routing policy changes. The changes will not take effect on the routing policy until the change delay timer expires.

A routing policy changes when one of the following events occurs:

· A routing policy is created.

· A routing policy node, if-match clause, or apply clause is added, modified, or deleted for a routing policy.

· An IPv4 prefix list, IPv6 prefix list, AS path list, community list, extended community list, or MAC list is added, modified, or deleted.

· The ACL used by an if-match clause changes.

To have enough time to complete routing policy configuration, you can specify the unlimited keyword for the command. Then, execute the undo form of the command after you complete the configuration.

If you modify the routing policy change delay timer before it expires, the timer will be reset.

Examples

# Set the routing policy change delay timer to 60 seconds.

<Sysname> system-view

[Sysname] route-policy-change delay-time 60

route-policy prefix-protocol-check

Use undo route-policy prefix-protocol-check to restore the default.

Syntax

route-policy prefix-protocol-check

undo route-policy prefix-protocol-check

Default

The routing policy does not check the IP protocol consistency between routes and the prefix list specified in an if-match clause:

· If the if-match clause uses an IPv6 address prefix list, all IPv4 routes can match the clause.

· If the if-match clause uses an IPv4 address prefix list, all IPv6 routes can match the clause.

Parameters

prefix-list-name: Specifies an IPv4 prefix list name, a case-sensitive string of 1 to 63 characters.

index index-number: Specifies an index number for an IPv4 prefix list item, in the range of 1 to 65535. An item with a smaller index number is matched first. If you do not specify this option, the index number starts from 10 and increases by 10 for each of the consecutive prefix list items. This option is required for target configuration. For more information about target configuration, see Fundamentals Configuration Guide.

permit: Specifies the permit mode. If a route matches the item, it passes the IPv4 prefix list. If a route does not match the item, the route is compared with the next item.

ip-address mask-length: Specifies an IPv4 prefix and mask length. The value range for the mask-length argument is 0 to 32.

greater-equal min-mask-length, less-equal max-mask-length: Specifies a prefix length range. The greater-equal keyword means "greater than or equal to" and the less-equal keyword means "less than or equal to." The prefix length range relation is mask-length <= min-mask-length <= max-mask-length <= 32.

· If only the min-mask-length argument is specified, the prefix length range is [ min-mask-length, 32 ].

· If only the max-mask-length argument is specified, the prefix length range is [ mask-length, max-mask-length ].

· If both the min-mask-length and max-mask-length arguments are specified, the prefix length range is [ min-mask-length, max-mask-length ].

Usage guidelines

An IPv4 prefix list is used to filter IPv4 addresses. It can contain multiple items, each of which specifies a range of IPv4 prefixes. The relation between the items is logical OR. If an item is passed, the IPv4 prefix list is passed. If no item is passed, the IP prefix list cannot be passed.

If both the ip-address and mask-length arguments are specified as 0.0.0.0 0, only the default route will be matched.

To match all routes, use 0.0.0.0 0 less-equal 32.

Examples

# Configure IP prefix list p1 to permit routes destined for network 10.0.0.0/8 and with mask length 17 or 18.

Parameters

ipv6-address: Specifies the next hop IPv6 address.

Usage guidelines

If you use this command to set a next hop for redistributed routes, the configuration does not take effect.

Examples

# Configure node 10 for routing policy policy1 to set next hop 3ffe:506::1 for IPv6 routes matching AS path list 1.

<Sysname> system-view

[Sysname] route-policy policy1 permit node 10

[Sysname-route-policy-policy1-10] if-match as-path 1

[Sysname-route-policy-policy1-10] apply ipv6 next-hop 3ffe:506::1

display ipv6 prefix-list

Use display ipv6 prefix-list to display IPv6 prefix list statistics.

Parameters

name prefix-list-name: Specifies an IPv6 prefix list by its name, a case-sensitive string of 1 to 63 characters. If you do not specify this option, the command displays statistics for all IPv6 prefix lists.

Examples

# Display the statistics for all IPv6 prefix lists.

<Sysname> display ipv6 prefix-list

if-match ipv6

Use if-match ipv6 to match IPv6 routes whose destination, next hop, or source address matches an ACL or IPv6 prefix list.

Use undo if-match ipv6 to remove the specified ACL or IPv6 prefix list match criterion.

Syntax

if-match ipv6 { address | next-hop | route-source } { acl { ipv6-acl-number | name ipv6-acl-name } | prefix-list prefix-list-name }

undo if-match ipv6 { address | next-hop | route-source } [ acl | prefix-list ]

Default

No ACL or IPv6 prefix list match criterion is configured.

Parameters

address: Matches the destination address of IPv6 routes.

next-hop: Matches the next hop of IPv6 routes.

route-source: Matches the source address of IPv6 routes.

acl ipv6-acl-number: Specifies an IPv6 ACL by its number. The value range for the ipv6-acl-number argument is 2000 to 3999 for the address keyword, and 2000 to 2999 for the next-hop and route-source keywords.

acl name ipv6-acl-name: Specifies an IPv6 ACL by its name, a case-insensitive string of 1 to 63 characters. The ACL name must start with a letter and cannot be all.

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

Usage guidelines

When you specify an IPv6 ACL, follow these guidelines:

· If the specified ACL does not exist or does not have any rules, all IPv6 routes can match the ACL.

· If a rule in the specified ACL is applied to a VPN instance, the rule does not take effect.

Examples

# Configure node 10 of routing policy policy1 to permit routes whose next hop matches IPv6 prefix list p1.

<Sysname> system-view

[Sysname] route-policy policy1 permit node 10

[Sysname-route-policy-policy1-10] if-match ipv6 next-hop prefix-list p1

ipv6 prefix-list

Use ipv6 prefix-list to configure an IPv6 prefix list or an item for it.

Use undo ipv6 prefix-list to remove an IPv6 prefix list or an item.

Syntax

ipv6 prefix-list prefix-list-name [ index index-number ] { deny | permit } ipv6-address { prefix-length [ greater-equal min-prefix-length ] [ less-equal max-prefix-length ] | inverse inverse-prefix-length }

undo ipv6 prefix-list prefix-list-name [ index index-number ]

Default

No IPv6 prefix lists exist.

Parameters

prefix-list-name: Specifies an IPv6 prefix list name, a case-sensitive string of 1 to 63 characters.

index index-number: Specifies an index number for an IPv6 prefix list item, in the range of 1 to 65535. An item with a smaller index number is matched first. If you do not specify this option, the index number starts from 10 and increases by 10 for each of the consecutive IPv6 prefix list items. This option is required for target configuration. For more information about target configuration, see Fundamentals Configuration Guide.

permit: Specifies the permit mode. If a route matches the item, it passes the IPv6 prefix list. If a route does not match the item, the route is compared with the next item.

ipv6-address: Specifies an IPv6 address.

prefix-length: Specifies the IPv6 prefix length. The value range for the prefix-length argument is 0 to 128.

The prefix length range relation is mask-length <= min-mask-length <= max-mask-length <= 128.

· If only the min-prefix-length argument is specified, the prefix length range is [ min-prefix-length, 128 ].

· If only the max-prefix-length argument is specified, the prefix length range is [ prefix-length, max-prefix-length ].

· If both the min-prefix-length and max-prefix-length arguments are specified, the prefix length range is [ min-prefix-length, max-prefix-length ].

inverse inverse-prefix-length: Matches IPv6 addresses from the least significant bit to the specified length. The value range for the inverse-prefix-length argument is 1 to 128.

Usage guidelines

An IPv6 prefix list is used to filter IPv6 addresses. An IPv6 prefix list can have multiple items, and each of them specifies a range of IPv6 prefixes. The relation between the items is logical OR. A route passing an item passes the IPv6 prefix list. A route passing no item does not pass the IPv6 prefix list.

If the ipv6-address prefix-length argument is specified as :: 0, only the default route matches.

To match all routes, configure :: 0 less-equal 128.

Examples

# Permit IPv6 addresses with a mask length between 32 bits and 64 bits.

<Sysname> system-view

[Sysname] ipv6 prefix-list abc permit :: 0 greater-equal 32 less-equal 64

# Deny IPv6 addresses with a prefix 3FFE:D00::/32 and a prefix length greater than or equal to 32 bits.

<Sysname> system-view

[Sysname] ipv6 prefix-list abc deny 3FFE:D00:: 32 less-equal 128
