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 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 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 fail-action-drop next-hop

Use apply fail-action-drop next-hop to set the action that drops matching packets when all next hops on an IPv6 policy node are invalid.

Use undo apply fail-action-drop next-hop to restore the default.

Syntax

apply fail-action-drop next-hop

undo apply fail-action-drop next-hop

Default

The drop action is not configured. The matching packets are forwarded based on the typical packet forwarding process if all next hops on the IPv6 policy node are invalid.

Usage guidelines

By default, the device uses the typical packet forwarding process to route matching packets when all next hops on the IPv6 policy node are unavailable. To drop all matching packets when all next hops on the IPv6 policy node are unavailable, use this command. This command is typically used in scenarios that require strict routing paths.

If no next hops are specified on the IPv6 policy node, this command drops all packets that match the node.

This command does not apply to software-forwarded packets.

Examples

# Set next hop 1::1 on IPv6 policy node 10 and configure the IPv6 policy node to drop matching packets when the next hop is invalid.

<Sysname> system-view

[Sysname] ipv6 policy-based-route policy1 permit node 10

[Sysname-pbr6-policy1-1] apply next-hop 1::1

[Sysname-pbr6-policy1-1] apply fail-action-drop next-hop

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 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

apply precedence

Table 3 Command output

Field

Description

Policy based routing information for interface XXXX (failed)

IPv6 PBR configuration and statistics on the interface.

This field displays failed in brackets if none of the nodes in the policy has been successfully issued to the driver. The failed status will persist even after the policy is successfully issued. To clear the failed status, you must remove the policy from the interface and then apply it on the interface again.

NOTE:

The failed status is available on a per-slot basis. To obtain this information, you must specify a slot number when you execute the command.

·     For a global interface (for example, a VLAN interface), which might have member physical interfaces on multiple slots, specify a slot that contains its member interfaces.

·     For a physical interface, specify its slot number.

node 0 deny(not support)

node 2 permit(no resource)

Match mode of the node, permit or deny.

If a node fails to be issued to the driver, the command displays the cause in brackets, which include:

·     not support—The device does not support the match criteria configured on the node.

·     no resource—No sufficient resources (for example, ACLs) are available for the node.

NOTE:

The cause is available only on a per-slot basis. To obtain this information, you must specify a slot number when you execute the command.

·     For a global interface (for example, a VLAN interface), which might have member physical interfaces on multiple slots, specify a slot that contains its member interfaces.

·     For a physical interface, specify its slot number.

if-match acl

Compares IPv6 packets with the IPv6 ACL.

apply next-hop

Specifies a next hop for permitted IPv6 packets.

Matched: 0 (no statistics resource)

Number of successful matches on the node. If the device does not have sufficient resources to count matches, this field displays no statistics resource in brackets.

NOTE:

The statistics collection failure cause is available only on a per-slot basis. To obtain this information, you must specify a slot number when you execute the command.

·     For a global interface (for example, a VLAN interface), which might have member physical interfaces on multiple slots, specify a slot that contains its member interfaces.

·     For a physical interface, specify its slot number.

Total matched

Total number of successful matches on all nodes.

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

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.
