Syntax

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

undo apply next-hop [ [ vpn-instance vpn-instance-name ] ip-address&<1-n> ]

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.

ip-address: Specifies the IP 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-n>: Indicates that the argument before it can be entered up to n times. The value of n is 2.

Usage guidelines

You can specify multiple next hops for backup by executing this command once or multiple times.

You can specify a maximum of two next hops for a node.

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 1.1.1.1.

<Sysname> system-view

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

[Sysname-pbr-aa-11] apply next-hop 1.1.1.1 direct

Table 2 Command output

Field	Description
Policy based routing information for interface Vlan-interface1(failed)	PBR configuration and statistics on VLAN-interface 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 1), failed can be displayed only when you specify the 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 1), not support and no resource can be displayed only when you specify the slot slot-number option for the command.
if-match acl	Matches packets against the ACL.
apply next-hop	Specify a next hop for permitted packets.
apply output-interface Vlan-interface2 track 1 (down)	Specify an output interface for permitted packets. The interface status includes the following: ·     up—The interface is up. ·     down—The interface is down at network layer. ·     inactive—The card that hosts the interface is not in position.
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 1), no statistics resource can be displayed only when you specify the 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

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.
