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.
ipv6-address: Specifies the IPv6 address of the default next hop. If you do not specify the vpn-instance vpn-instance-name option, 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.
&<1-2>: Indicates that the argument before it can be entered up to two times.
Usage guidelines
You can specify multiple default next hops for backup 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.

apply fail-action-drop next-hop
Use apply fail-action-drop next-hop to set the action that drops matching packets when all next hops on an IPv6 policy node are invalid.
Use undo apply fail-action-drop next-hop to restore the default.
Syntax
apply fail-action-drop next-hop
undo apply fail-action-drop next-hop
Default
The drop action is not configured. The matching packets are forwarded based on the typical packet forwarding process if all next hops on the IPv6 policy node are invalid.
Views
IPv6 policy node view
Predefined user roles
network-admin
Usage guidelines
By default, the device uses the typical packet forwarding process to route matching packets when all next hops on the IPv6 policy node are unavailable. To drop all matching packets when all next hops on the IPv6 policy node are unavailable, use this command. This command is typically used in scenarios that require strict routing paths.
If no next hops are specified on the IPv6 policy node, this command drops all packets that match the node.
This command does not apply to software-forwarded packets.
Examples
# Set next hop 1::1 on IPv6 policy node 10 and configure the IPv6 policy node to drop matching packets when the next hop is invalid.
<Sysname> system-view
[Sysname] ipv6 policy-based-route policy1 permit node 10
[Sysname-pbr6-policy1-1] apply next-hop 1::1
[Sysname-pbr6-policy1-1] apply fail-action-drop next-hop
apply next-hop
Use apply next-hop to set next hops.
Use undo apply next-hop to remove next hops.
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 instance 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.
weight weight-value: Specifies a load sharing weight for the next hop, in the range of 1 to 100. The default is 10. If you specify weights 1, 1, and 2 for three next hops, they share 1/4, 1/4, and 1/2 of the whole traffic, respectively.
&<1-2>: Indicates that the argument before it can be entered up to two times.
Usage guidelines
You can specify multiple next hops for backup in one command line or by executing this command multiple times.
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.

Policy based routing information for interface XXXX (failed) |
IPv6 PBR configuration and statistics on the interface. This field displays failed in brackets if none of the nodes in the policy has been successfully issued to the driver. The failed status will persist even after the policy is successfully issued. To clear the failed status, you must remove the policy from the interface and then apply it on the interface again. NOTE: The failed status is available on a per-slot basis. To obtain this information, you must specify a slot number when you execute the command. · For a global interface (for example, a VLAN interface), which might have member physical interfaces on multiple slots, specify a slot that contains its member interfaces. · For a physical interface, specify its slot number. |
|
node 0 deny(not support) node 2 permit(no resource) |
Match mode of the node, permit or deny. If a node fails to be issued to the driver, the command displays the cause in brackets, which include: · not support—The device does not support the match criteria configured on the node. · no resource—No sufficient resources (for example, ACLs) are available for the node. NOTE: The cause is available only on a per-slot basis. To obtain this information, you must specify a slot number when you execute the command. · For a global interface (for example, a VLAN interface), which might have member physical interfaces on multiple slots, specify a slot that contains its member interfaces. · For a physical interface, specify its slot number. |

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 except the packets destined for the sender. This feature might affect local services. 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

Predefined user roles
network-admin
Parameters
policy-name: Specifies a policy by its name, a case-sensitive string of 1 to 19 characters. The specified policy must already exist.
share-mode: Applies the IPv6 policy in resource sharing mode. In this mode, all interfaces on a device with the same IPv6 policy applied share one hardware resource. If you do not specify this keyword, each interface occupies one independent hardware resource. You can apply only one ACL, QoS policy, or PBR policy with the share-mode keyword specified to one direction of an interface. For information about ACL and QoS policies, see ACL commands and QoS policy commands in ACL and QoS Command Reference.
Usage guidelines
You can set only one mode for the policy on an interface. Before you change the mode of the policy, you must first remove the current policy from the interface.
Examples
# Apply policy aaa to VLAN-interface 2.
<Sysname> system-view
[Sysname] interface vlan-interface 2
[Sysname-Vlan-interface2] ipv6 policy-based-route aaa

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. A smaller number has a higher priority. The value range for the node-number argument is 0 to 2047.
Usage guidelines
To delete an IPv6 policy that has already applied to an interface, you must delete the policy from the interface first.
If a policy node is specified, the undo ipv6 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 node is specified, the command deletes the whole policy.
Examples
# Create permit-mode Node 10 for IPv6 policy aaa and enter its view.

Predefined user roles
network-admin
Parameters
policy-name: Specifies an IPv6 policy by its name, a case-sensitive string of 1 to 19 characters. The IPv6 policy must already exist.
vlan-interface interface-list: Specifies a space-separated list of up to eight VLAN interface items. Each item specifies a VLAN interface or a range of VLAN interfaces in the form of interface-type interface-number1 to interface-type interface-number2. The value for interface-number2 must be greater than or equal to the value for interface-number1. The interface type is VLAN interface.
Usage guidelines
You cannot specify different policies for a VLAN interface. You can use either of the following commands to specify a policy for a VLAN interface:
· ipv6 policy-based-route apply
· ipv6 policy-based-route (interface view)
To specify an IPv6 policy for multiple VLAN interfaces, you can use either of the following methods:
· Method 1—Execute the ip policy-based-route apply command. The policy is issued to the driver for all interfaces at the same time. This method reduces hardware entries and saves system resources. You can use this method to specify an IPv6 policy for VLAN interfaces that do not exist.
· Method 2—Use the interface range command to create an interface range, and specify a policy for the interface range. The policy is issued to the driver for each interface. The system creates a hardware entry for each interface.
Examples
# Specify IPv6 policy aaa for VLAN-interface 100 through VLAN-interface 200.
<Sysname> system-view
[Sysname] ipv6 policy-based-route aaa apply vlan-interface 100 to 200
