The switch operates in IRF or standalone (the default) mode. For more information about IRF, see IRF Configuration Guide.
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 ] { ip-address [ direct ] [ track track-entry-number ] }&<1-2>
undo apply next-hop [ [ vpn-instance vpn-instance-name ] { ip-address }&<1-2> ]
Default
No next hop is set.

Parameters
vpn-instance vpn-instance-name: Specifies an MPLS L3VPN by its name, a case-sensitive string of 1 to 31 characters. The specified VPN must already exist. If no VPN is specified, the next hop belongs to the public network.
ip-address: Specifies the next-hop IP address.
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
To configure two next hops for a policy node, you can enter two next hops in one command line or execute the command twice. The first next hop configured is the active next hop and the second is the standby next hop. With two next hops specified, only the active next hop takes effect. When the active next hop is not available, the standby next hop takes effect. When neither next hop is available, packets are forwarded according to the routing table.
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

Parameters
interface-type interface-number: Specifies an interface by its type and number.
slot slot-number: Displays the PBR configuration and statistics on a card. The slot-number argument is the number of the slot that holds the card. (In standalone mode.)

Total matched: 0
Table 2 Command output
Field |
Description |
Policy based routing information for interface GigabitEthernet3/0/1(failed) |
PBR configuration and statistics on GigabitEthernet 3/0/1. 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 |
Matches packets against the ACL. |
apply next-hop |
Specify 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
acl-number: Specifies an ACL by its number in the range of 2000 to 3999 for a basic ACL and in the range of 3000 to 3999 for an advanced ACL.
Examples
# Configure Node 11 of policy aa to permit the packets matching ACL 2011.

ip policy-based-route
Use ip policy-based-route to configure interface PBR by applying a policy on an interface.
Use undo ip policy-based-route to remove the configuration.
Syntax

Default
No policy is applied on 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 on an interface. Before you apply a new policy, you must first remove the current policy from the interface.
Examples
# Apply policy aaa on VLAN-interface 2.
<Sysname> system-view
[Sysname] vlan 2
[Sysname-Vlan2] interface vlan-interface 2
[Sysname-Vlan-interface2] ip policy-based-route aaa

policy-based-route
Use policy-based-route to create a policy node and enter policy node view.
Use undo policy-based-route to remove a policy or policy node.
Syntax
policy-based-route policy-name [ deny | permit ] node node-number
undo policy-based-route policy-name [ deny | node node-number | permit ]
Default
No policy node is created.

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 65535. A smaller number has a higher priority.
Usage guidelines
If the specified policy node already exists, the command directly places you into policy node view.
A policy that has been applied on an interface 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.
Examples
# Create permit-mode of Node 10 for policy policy1 and enter policy node view.
<Sysname> system-view
[Sysname] policy-based-route policy1 permit node 10
[Sysname-pbr-policy1-10]
