IPv6 policy-based routing commands

apply next-hop

Use apply next-hop to set a next hop.

Use undo apply next-hop to remove the configuration.

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 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 twice at most.

Usage guidelines

You can specify two next hops for backup by executing this command twice.

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

display ipv6 policy-based-route

Table 2 Command output

Field	Description
Policy based routing information for interface GigabitEthernet1/0/1(failed)	IPv6 PBR configuration and statistics on GigabitEthernet 1/0/1. failed indicates the policy (including all its nodes) failed to be assigned to the driver. For a global interface (with only one-dimensional interface number, for example, VLAN-interface 10), failed can be displayed only when you specify the slot slot-number or chassis chassis-number slot slot-number option for the command.
node 0 deny(not support) node 2 permit(no resource)	Match mode of the node, permit or deny. not support means the device does not support the match criteria configured on the node. no resource means the device has insufficient ACL resources, and failed to assign ACL resources to the node. For a global interface (with only one-dimensional interface number, for example, VLAN-interface 10), not support and no resource can be displayed only when you specify the slot slot-number or chassis chassis-number slot slot-number option for the command.
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 (no statistics resource indicates insufficient statistics resources). For a global interface (with only one-dimensional interface number, for example, VLAN-interface 10), no statistics resource can be displayed only when you specify the slot slot-number or chassis chassis-number slot slot-number option for the command.
Total matched	Total number of successful matches on all nodes.

Parameters

acl6-number: Specifies an 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 acl6-name: Specifies an ACL by its name, a case-insensitive string of 1 to 63 characters starting with letter a to z or A to Z. The ACL name cannot be all.

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 remove the configuration.

Syntax

ipv6 local policy-based-route policy-name

undo ipv6 local policy-based-route

Default

No policy is referenced 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. This feature might affect local services, such as ping and Telnet. 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 remove the configuration.

Syntax

ipv6 policy-based-route policy-name

Default

No IPv6 is applied to an interface.

Parameters

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

Usage guidelines

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

Examples

# Apply policy aaa to VLAN-interface 2.

<Sysname> system-view

[Sysname] vlan 2

[Sysname-Vlan2] interface vlan-interface 2

[Sysname-Vlan-interface2] ipv6 policy-based-route aaa

ipv6 policy-based-route (system view)

Use ipv6 policy-based-route to create an IPv6 policy or policy node and enter IPv6 policy node view. If the specified IPv6 policy node already exists, the command directly places you into IPv6 policy node view.

Use undo ipv6 policy-based-route to remove an IPv6 policy or IPv6 policy node.

Syntax

ipv6 policy-based-route policy-name [ deny | permit ] node node-number

undo ipv6 policy-based-route policy-name [ deny | node node-number | permit ]

Default

No IPv6 policy node is created.

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, in the range of 0 to 255. A smaller number has a higher priority.

Usage guidelines

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

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

Examples

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

<Sysname> system-view

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

[Sysname-pbr6-aaa-10]
