Parameters

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance to which the default next hop belongs. The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. If the default next hop belongs to the public network, do not specify this option.

ipv6-address: Specifies the IPv6 address of the default next hop.

track track-entry-number: Specifies a track entry by its number in the range of 1 to 1024.

&<1-2>: Indicates that you can specify up to two default next hops.

Usage guidelines

You can specify multiple default next hops for backup or load sharing in one command line or by executing this command multiple times.

With a default next hop specified, the undo apply default-next-hop command removes the default next hop.

Without any default next hop specified, the undo apply default-next-hop command removes all default next hops.

Examples

# Set a directly-connected default next hop of 1:1::1:1.

<Sysname> system-view

[Sysname] ipv6 policy-based-route aa permit node 11

[Sysname-pbr6-aa-11] apply default-next-hop 1:1::1:1 direct

apply default-srv6-be

Use apply default-srv6-be to configure packet forwarding in default SRv6 BE mode.

Use undo apply default-srv6-be to remove the configuration.

Syntax

apply default-srv6-be remote-sid { remote-sid locator-prefix-len }&<1-2>

undo apply default-srv6-be remote-sid [ { remote-sid locator-prefix-len }&<1-2> ]

Default

network-admin

Parameters

remote-sid remote-sid: Specifies the default SRv6 BE destination node SID.

locator-prefix-len: Specifies the locator length for the destination node SID, in the range of 32 to 120.

&<1-2>: Indicates that the argument before it can be entered up to two times.

Usage guidelines

You can use the remote-sid and locator-prefix-len arguments to uniquely identify a locator. The device performs SRv6 encapsulation for matching packets (encapsulates an IPv6 header with the default SRv6 BE destination node SID used as the destination address), and forwards them through the IGP route associated with the locator. You can specify up to two destination node SIDs for the default SRv6 BE mode for backup in one command line or by executing this command multiple times. When you specify up to two SIDs, you cannot specify new SIDs.

With a default SRv6 BE destination node SID specified, the undo form of the command removes the specified default SRv6 BE destination node SID. Without any default SRv6 BE destination node SIDs specified, the undo form of the command removes all configured default SRv6 BE destination node SIDs.

Examples

# Configure packet forwarding in default SRv6 BE mode. Specify the default SRv6 BE destination node SID as 1000::1 and the locator length as 32.

<Sysname> system-view

[Sysname] ipv6 policy-based-route aa permit node 1

[Sysname-pbr6-aa-1] apply default-srv6-be remote-sid 1000::1 32

apply default-srv6-policy

Use apply default-srv6-policy to set default SRv6 TE policies.

Use undo apply default-srv6-policy to remove default SRv6 TE policies.

Syntax

apply default-srv6-policy { endpoint color [ { sid | vpnsid } sid ] }&<1-2>

undo apply default-srv6-policy [ { endpoint color }&<1-2> ]

Default

No default SRv6 TE policies are set.

Parameters

endpoint: Specifies a default SRv6 TE policy by its endpoint IPv6 address.

color: Specifies a default SRv6 TE policy by its color attribute value in the range of 0 to 4294967295.

sid: Indicates that the SRv6 SID of the destination node is a public network SID.

vpnsid: Indicates that the SRv6 SID of the destination node is a VPN SID.

sid: Specifies the SRv6 SID of the destination node in IPv6 address format.

&<1-2>: Indicates that you can specify up to two default SRv6 TE policies.

Usage guidelines

You can specify multiple default SRv6 TE policies for backup in one command line or by executing this command multiple times. The first available default SRv6 TE policy selected according to configuration order will be used to forward matching packets.

Without any default SRv6 TE policy specified, the undo apply default-srv6-policy command removes all default SRv6 TE policies.

Use the { sid | vpnsid } sid option on the source node to specify the SRv6 SID of the destination node and its attribute information (public network SID or VPN SID). The attribute information is not encapsulated in packets and does not affect packet forwarding.

When encapsulating packets matching the default SRv6 TE policy, the source node adds the SRv6 SID of the destination node to the SRH header of the packets. The SRv6 SID is added after the SID list of the default SRv6 TE policy. Upon receiving the packets forwarded based on the default SRv6 TE policy, the destination node uses the specified SRv6 SID to perform an SRv6 local SID forwarding table lookup to forward the packets.

Examples

# Specify a default SRv6 TE policy with destination node IPv6 address 1000::1, color attribute value 10, and destination node SRv6 SID 2000::2.

<Sysname> system-view

[Sysname] ipv6 policy-based-route aa permit node 1

[Sysname-pbr6-aa-1] apply default-srv6-policy 1000::1 10 sid 2000::2

apply next-hop

Use apply next-hop to set next hops.

Use undo apply next-hop to remove next hops.

Syntax

apply next-hop [ vpn-instance vpn-instance-name ] { ipv6-address [ direct ] [ track track-entry-number ] } &<1-2>

undo apply next-hop [ [ vpn-instance vpn-instance-name ] ipv6-address&<1-2> ]

Default

No next hops are set.

Parameters

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance to which the next hop belongs. The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. If the next hop belongs to the public network, do not specify this option.

ipv6-address: Specifies the IPv6 address of the next hop.

direct: Specifies that the next hop must be directly connected to take effect.

track track-entry-number: Specifies a track entry by its number in the range of 1 to 1024.

&<1-2>: Indicates that you can specify up to two next hops.

Usage guidelines

You can specify multiple next hops for backup or load sharing in one command line or by executing this command multiple times.

With a next hop specified, the undo apply next-hop command removes the next hop.

Without any next hop specified, the undo apply next-hop command removes all next hops.

Examples

# Set a directly-connected next hop of 1::1.

<Sysname> system-view

[Sysname] ipv6 policy-based-route aa permit node 11

[Sysname-pbr6-aa-11] apply next-hop 1::1

apply output-interface

Use apply output-interface to set output interfaces.

Use undo apply output-interface to remove output interfaces.

Syntax

apply output-interface { interface-type interface-number [ track track-entry-number ] }

undo apply output-interface [ { interface-type interface-number } ]

Default

network-admin

Parameters

interface-type interface-number: Specifies an interface by its type and number.

track track-entry-number: Specifies a track entry by its number in the range of 1 to 1024.

Usage guidelines

The output interface must be P2P type. Using a non-P2P output interface can result in forwarding failures when the interface has multiple next hops. Non-P2P interfaces include broadcast and NBMA interfaces such as Ethernet and virtual-template interfaces.

With an output interface specified, the undo apply output-interface command removes the output interface.

Without any output interface specified, the undo apply output-interface command removes all output interfaces.

Examples

# Specify Ten-GigabitEthernet 3/0/1 as the output interface for IPv6 packets.

<Sysname> system-view

[Sysname] ipv6 policy-based-route aa permit node 11

[Sysname-pbr6-aa-11] apply output-interface ten-gigabitethernet 3/0/1

apply precedence

Use apply precedence to set a precedence for IPv6 packets.

Use undo apply precedence to restore the default.

Syntax

apply precedence { type | value }

Parameters

remote-sid remote-sid: Specifies the SRv6 BE destination node SID.

locator-prefix-len: Specifies the locator length for the destination node SID, in the range of 32 to 120.

&<1-2>: Indicates that the argument before it can be entered up to two times.

Usage guidelines

You can use the remote-sid and locator-prefix-len arguments to uniquely identify a locator. The device performs SRv6 encapsulation for matching packets (encapsulates an IPv6 header with the SRv6 BE destination node SID used as the destination address), and forwards them through the IGP route associated with the locator. You can specify up to two destination node SIDs for the SRv6 BE mode for backup in one command line or by executing this command multiple times. When you specify up to two SIDs, you cannot specify new SIDs.

With an SRv6 BE destination node SID specified, the undo form of the command removes the specified SRv6 BE destination node SID. Without any SRv6 BE destination node SIDs specified, the undo form of the command removes all configured SRv6 BE destination node SIDs.

Examples

# Configure packet forwarding in SRv6 BE mode. Specify the SRv6 BE destination node SID as 1000::1 and the locator length as 32.

<Sysname> system-view

[Sysname] ipv6 policy-based-route aa permit node 1

Parameters

endpoint: Specifies an SRv6 TE policy by its endpoint IPv6 address.

color: Specifies an SRv6 TE policy by its color attribute value in the range of 0 to 4294967295.

sid: Indicates that the SRv6 SID of the destination node is a public network SID.

vpnsid: Indicates that the SRv6 SID of the destination node is a VPN SID.

sid: Specifies the SRv6 SID of the destination node in IPv6 address format.

&<1-2>: Indicates that you can specify up to two SRv6 TE policies.

Usage guidelines

You can specify multiple SRv6 TE policies for backup in one command line or by executing this command multiple times. The first available SRv6 TE policy selected according to configuration order will be used to forward matching packets.

Without any SRv6 TE policy specified, the undo apply srv6-policy command removes all SRv6 TE policies.

Use the { sid | vpnsid } sid option on the source node to specify the SRv6 SID of the destination node and its attribute information (public network SID or VPN SID). The attribute information is not encapsulated in packets and does not affect packet forwarding.

When encapsulating packets matching the SRv6 TE policy, the source node adds the SRv6 SID of the destination node to the SRH header of the packets. The SRv6 SID is added after the SID list of the SRv6 TE policy. Upon receiving the packets forwarded based on the SRv6 TE policy, the destination node uses the specified SRv6 SID to perform an SRv6 local SID forwarding table lookup to forward the packets.

if-match acl

Use if-match acl to set an ACL match criterion.

Use undo if-match acl to restore the default.

Syntax

if-match acl { ipv6-acl-number | name ipv6-acl-name }

undo if-match acl

Default

No ACL match criterion is set.

Parameters

ipv6-acl-number: Specifies an IPv6 ACL by its number in the range of 2000 to 3999. The value range of a basic ACL is 2000 to 2999 and that of an advanced ACL is 3000 to 3999.

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

Usage guidelines

If the specified ACL does not exist or has no rules configured, no packets will match the ACL.

If the vpn-instance keyword is specified for an ACL rule, the rule applies to only VPN packets. If the vpn-instance keyword is not specified, the rule applies to only public network packets.

Examples

# Configure Node 10 of policy aa to permit the packets matching ACL 2000.

<Sysname> system-view

[Sysname] ipv6 policy-based-route aa permit node 10

[Sysname-pbr6-aa-10] if-match acl 2000

# Configure Node 10 of policy aa to permit the packets matching ACL aaa.

ipv6 local policy-based-route

Use ipv6 local policy-based-route to configure IPv6 local PBR based on a specified policy.

Use undo ipv6 local policy-based-route to restore the default.

Syntax

ipv6 local policy-based-route policy-name

undo ipv6 local policy-based-route

Default

No policy is specified for IPv6 local PBR.

Parameters

policy-name: Specifies a policy by its name, a case-sensitive string of 1 to 19 characters. The specified IPv6 policy must already exist.

Usage guidelines

You can apply only one policy locally. Before you apply a new policy, you must first remove the current policy.

IPv6 local PBR is used to route locally generated packets except the packets destined for the sender. This feature might affect local services. Do not configure IPv6 local PBR unless doing so is required.

Examples

# Configure IPv6 local PBR based on policy aaa.

<Sysname> system-view

[Sysname] ipv6 local policy-based-route aaa

ipv6 policy-based-route (interface view)

Use ipv6 policy-based-route to configure IPv6 interface PBR by applying an IPv6 policy to an interface.

Use undo ipv6 policy-based-route to restore the default.

Syntax

ipv6 policy-based-route policy-name [ share-mode ]

undo ipv6 policy-based-route

Default

No IPv6 is applied to an interface.

Views

Interface view

Predefined user roles

network-admin

Parameters

policy-name: Specifies a policy by its name, a case-sensitive string of 1 to 19 characters. The specified policy must already exist.

share-mode: Applies the IPv6 policy in resource sharing mode. In this mode, all interfaces on an interface card with the same IPv6 policy applied share one hardware resource. If you do not specify this keyword, each interface occupies one independent hardware resource. You can apply only one ACL, QoS policy, or PBR policy with the share-mode keyword specified to one direction of an interface. For information about ACL and QoS policies, see ACL commands and QoS policy commands in ACL and QoS Command Reference.

Usage guidelines

Typically, an IPv6 policy on different interfaces of a card uses different hardware resources. To avoid resource usage overhead, you can set the resource sharing mode when applying the policy to each interface. This mode allows the policy on different interfaces of the card to use the same hardware resources.

You can apply only one policy to an interface. Before you apply a new policy, remove the current policy from the interface.

You can set only one mode for the policy on an interface. Before you change the mode of the policy, you must first remove the current policy from the interface.

Examples

# Apply policy aaa to Ten-GigabitEthernet 3/0/1.

<Sysname> system-view

[Sysname] interface ten-gigabitethernet 3/0/1

[Sysname-Ten-GigabitEthernet3/0/1] ipv6 policy-based-route aaa

Parameters

policy-name: Specifies a policy name, a case-sensitive string of 1 to 19 characters.

deny: Specifies the match mode for the policy node as deny.

permit: Specifies the match mode for the policy node as permit (default mode).

node node-number: Specifies the number of the IPv6 policy node. A smaller number has a higher priority. The value range for the node-number argument is 0 to 255.

Usage guidelines

To delete an IPv6 policy that has already applied to an interface, you must delete the policy from the interface first.

If a policy node is specified, the undo ipv6 policy-based-route command deletes the specified policy node. If a match mode is specified, the command deletes all nodes configured with the match mode. If no node is specified, the command deletes the whole policy.

Examples

# Create permit-mode Node 10 for IPv6 policy aaa and enter its view.

<Sysname> system-view

[Sysname] ipv6 policy-based-route aaa permit node 10

Usage guidelines

The IPv6 PBR logging feature helps the administrator locate and fix faults. The feature logs IPv6 PBR events and sends the logs to the information center. The information center processes the logs according to output rules. For more information about the information center, see Network Management and Monitoring Configuration Guide.

Excessive IPv6 PBR log messages degrade the performance of the device. To avoid this problem, disable the IPv6 PBR logging feature.
