IPv6 policy-based routing commands

apply default-next-hop

Use apply default-next-hop to set default next hops.

Use undo apply default-next-hop to remove default next hops.

Syntax

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

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

Default

No default next hops are 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 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 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-output-interface

Use apply default-output-interface to set default output interfaces.

Use undo apply default-output-interface to remove default output interfaces.

Syntax

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

undo apply default-output-interface [ interface-type interface-number ]

Default

No default output interfaces are set.

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 default output interface must be P2P type. Using a non-P2P default output interface can result in forwarding failures when the interface has multiple next hops. Non-P2P interfaces include broadcast and non-broadcast multi-access (NBMA) interfaces such as Ethernet and virtual-template interfaces. In NBMA networks, packets are sent in unicast.

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

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

As a best practice, do not specify the interface of a VXLAN tunnel automatically created by EVPN for this command.

Examples

# Specify HundredGigE 1/0/1 as the default output interface for IPv6 packets.

<Sysname> system-view

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

[Sysname-pbr6-aa-11] apply default-output-interface hundredgige 1/0/1

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 | inbound-vpn ] ipv6-address&<1-2> ]

Default

No next hops are 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 the 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 the argument before it can be entered up to two times.

Usage guidelines

You can specify multiple next hops for backup 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

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

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 to use the same hardware resources on different interfaces of the card.

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.

You can apply only one ACL, QoS policy, or IPv6 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.

You cannot specify the share-mode keyword for the command if you have configured the apply statistics command for the IPv6 policy.

Examples

# Configure IPv6 local PBR based on policy aaa.

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: Sets the resource sharing mode for the policy. An IPv6 policy in this mode uses the same hardware resources on different interfaces of a card. If you do not specify this keyword, the policy uses different hardware resources.

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.

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 System Management Configuration Guide.

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