vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. The specified VPN instance must already exist.

ipv6-address: Specifies the IPv6 address of the default next hop. If you do not specify the vpn-instance vpn-instance-name option, the default next hop belongs to the public network.

direct: Specifies a directly connected 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 the argument before it can be entered up to two times.

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 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 hop is set.

Parameters

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. The specified VPN instance must already exist.

ipv6-address: Specifies the IPv6 address of a next hop. If you do not specify the vpn-instance vpn-instance-name option, the next hop belongs to the public network.

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, each of which can be associated with a track entry.

Usage guidelines

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

If you do not specify a default next hop when you execute the undo form of this command, all next hops on the node are removed.

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

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 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

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 policy in resource sharing mode. All interfaces applied with the policy on a card use the same hardware resources. If you do not specify this keyword, the interfaces use different hardware resources. On an interface, you can configure only one application in QoS and ACL resource sharing mode for traffic in one direction. The device supports only the packet filtering, QoS policy, and PBR applications. For information about packet filtering and QoS policies, see ACL commands and QoS policy commands in ACL and QoS Command Reference.

Usage guidelines

Typically, each interface on a card uses different hardware resources for a policy. To avoid resource usage overhead, you can specify the resource sharing mode when applying the policy to each interface. The interfaces will use the same hardware resources.

You can specify only one mode for the IPv6 policy on an interface. Before you change the mode of the IPv6 policy, you must first remove the current IPv6 policy from the interface.

The resource sharing mode is supported only on CSPEX (excluding CSPEX-1204 and CSPEX-1104-E) or CEPC cards.

Examples

# Apply policy aaa to GigabitEthernet 3/1/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 3/1/1

[Sysname-GigabitEthernet3/1/1] 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.

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.
