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. This option does not take effect.

ip-address: Specifies the IP address of the default next hop.

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 twice at most.

Usage guidelines

This command is not supported on the following interface modules:

·     EA interface modules.

·     EB interface modules.

·     SE interface modules:

¡     LSU1GP24TXSE0.

¡     LSU1GT48SE0.

¡     LSU1GP48SE0.

You can specify a maximum of two default next hops for backup in one command line or by executing this command twice.

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

Table 2 Command output

Field	Description
Policy based routing information for interface GigabitEthernet1/0/1(failed)	PBR configuration and statistics on GigabitEthernet 1/0/1. failed indicates that the policy (including all its nodes) failed to be assigned to the driver. For a global interface (with only a 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 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 a 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 packets with the ACL.
apply next-hop	Specifies a next hop for permitted 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 a 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

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 locally. Before you apply a new policy, you must first remove the current policy.

Local PBR is used to route locally generated packets. This feature might affect local services, such as ping and Telnet. Do not configure local PBR unless doing so is required.

Examples

# Configure local PBR based on policy aaa.

<Sysname> system-view

[Sysname] ip local policy-based-route 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.

Usage guidelines

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

Examples

# Apply policy aaa to VLAN-interface 2.

Parameters

policy-name: Specifies a policy by its 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 a policy node by its number in the range of 0 to 255. A smaller number has a higher priority.

Usage guidelines

A policy that has been applied to an interface or locally cannot be removed. To remove it, you must first cancel the application.

·     If a policy node is specified, the undo 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 policy node or match mode is specified, the command removes the whole policy.
