Parameters
public: Specifies the forwarding table for the public network.
vpn-instance: Specifies the forwarding table for the specified MPLS L3VPN instances.
vpn-instance-name&<1-4>: Specifies a space-separated list of up to four VPN instance names. A VPN instance name is a case-sensitive string of 1 to 31 characters. The specified VPN instance must already exist.
Usage guidelines
Use this command only in special scenarios that require sending packets received from one network to another network, for example, from a VPN to the public network, or from one VPN to another VPN.
You can repeat this command to specify the forwarding tables for the public network and VPN instances. The device forwards the matching packets by using the first available forwarding table selected in the order in which they are specified.
If you specify the vpn-instance keyword without specifying any VPN instances when you execute the undo form of this command, all the VPN instances are removed from the policy node.
After all the forwarding tables on the policy node are removed, the default forwarding behavior restores.
Examples
# Specify the VPN 1 and VPN 2 forwarding tables on node 10. In this example, VPN 1 and VPN 2 already exist.
<Sysname> system-view
[Sysname] policy-based-route policy1 permit node 10
[Sysname-pbr-policy1-10] apply access-vpn vpn-instance vpn1 vpn2
# Specify the public network forwarding table on node 10.
<Sysname> system-view
[Sysname] policy-based-route policy1 permit node 10

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.
inbound-vpn: Specifies the VPN instance where the inbound interface belongs.
ip-address: Specifies the IP address of a default next hop. If you do not specify the vpn-instance vpn-instance-name option or the inbound-vpn keyword, 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.
&<1-4>: Indicates that you can specify up to four default next hops, each of which can be associated with a track entry.
Usage guidelines
You can specify multiple default next hops for backup or load sharing 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.

Parameters
interface-type interface-number: Specifies an interface by its type and number.
track track-entry-number: Specifies a track entry by its number in the range of 1 to 1024.
&<1-4>: Indicates that you can specify up to four interfaces, each of which can be associated with a track entry.
Usage guidelines
You can specify multiple default output interfaces for backup or load sharing in one command line or by executing this command multiple times.
The default output interface must be P2P type. Using a non-P2P default output interface can result in forwarding failures when the interface has multiple next hops. Non-P2P interfaces include broadcast and non-broadcast multi-access (NBMA) interfaces such as Ethernet and virtual-template interfaces. In NBMA networks, packets are sent in unicast.
With a default output interface specified, the undo apply default-output-interface command removes the default output interface.
Without any default output interface specified, the undo apply default-output-interface command removes all default output interfaces.
Examples
# Specify GigabitEthernet 1/2/5/1 as the default output interface for IP packets.
<Sysname> system-view
[Sysname] policy-based-route aa permit node 11
[Sysname-pbr-aa-11] apply default-output-interface gigabitethernet 1/2/5/1

Parameters
default-next-hop: Enables load sharing among multiple default next hops.
default-output-interface: Enables load sharing among multiple default output interfaces.
next-hop: Enables load sharing among multiple next hops.
output-interface: Enables load sharing among multiple output interfaces.
Usage guidelines
Multiple next hops, output interfaces, default next hops, or default output interfaces operate in either primary/backup or load sharing mode. For example:
· Primary/backup mode—The first configured output interface is used. When the primary output interface fails, the first configured backup output interface takes over.
· Load sharing mode—Multiple output interfaces load share traffic on a per-packet basis in turn, according to the configuration order.
|
NOTE: Multiple next hops load share traffic according to their weights. By default, all next hops have the same weight and traffic is load balanced among them. |

Usage guidelines
VPN remark action marks the matching packets as belonging to the VPN instance to which they are forwarded based on the apply access-vpn vpn-instance command. All subsequent service modules of PBR handle the packets as belonging to the re-marked VPN instance.
If the VPN remark action is not enabled, the forwarded matching packets are marked as belonging to the VPN instance or the public network from which they were received.
VPN remark action applies only to packets that have been successfully forwarded based on the apply access-vpn vpn-instance command.
Examples
# Forward packets that match ACL 3000 based on the forwarding table of VPN instance vpn1 and perform VPN remark action on the successfully forwarded packets.
<Sysname> system-view
[Sysname] policy-based-route aaa permit node 10
[Sysname-pbr-aaa-10] if-match acl 3000

Usage guidelines
A policy that has been applied to an interface or locally cannot be deleted. To delete it, you must first cancel the application.
· If a policy node is specified, the undo 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 policy node or match mode is specified, the command deletes the whole policy.

# Create permit-mode of Node 10 for policy policy1 and enter its view.
<Sysname> system-view
