IPv6 policy-based routing commands
apply loadshare
Use apply loadshare to enable load sharing among multiple next hops.
Use undo apply loadshare to restore the default.
Syntax
apply loadshare next-hop
undo apply loadshare next-hop
Default
Multiple next hops operate in primary/backup mode.
Views
IPv6 policy node view
Predefined user roles
network-admin
Parameters
next-hop: Enables load sharing among multiple next hops.
Usage guidelines
Multiple next hop options operate in either primary/backup or load sharing mode. The following description uses multiple next hops as an example:
· Primary/backup mode—A next hop is selected from all next hops in configuration order for packet forwarding, with all remaining next hops as backups. When the selected next hop fails, the next available next hop takes over.
· Load sharing mode—Matching traffic is distributed across the available next hops. If the traffic does not match any fast forwarding entries, per-packet load sharing is performed. If the traffic matches a fast forwarding entry, per-flow load sharing is performed.
Examples
# Enable load sharing among multiple next hops.
<Sysname> system-view
[Sysname] ipv6 policy-based-route aa permit node 11
[Sysname-pbr6-aa-11] apply next-hop 1::1 2::2
[Sysname-pbr6-aa-11] apply loadshare next-hop
Related commands
apply 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 hops are set.

network-admin
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 or the inbound-vpn keyword, 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.
&<1-2>: Indicates that you can repeat the previous group of parameters to configure up to two next hops.
Usage guidelines
You can specify multiple next hops for backup or load sharing 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.
<Sysname> system-view
[Sysname] ipv6 policy-based-route aa permit node 11
[Sysname-pbr6-aa-11] apply next-hop 1::1

apply output-interface
Use apply output-interface to set output interfaces.
Use undo apply output-interface to remove output interfaces.
Syntax

Default
No output interfaces are set.

Parameters
NULL 0: Specifies interface Null 0.
Usage guidelines
You can specify only interface Null 0 as the output interface.
Examples
# Specify Null 0 as the output interface for IPv6 packets.
<Sysname> system-view
[Sysname] ipv6 policy-based-route aa permit node 11
[Sysname-pbr6-aa-11] apply output-interface NULL 0
apply statistics
Use apply statistics to enable match counting on an IPv6 policy node.
Use undo apply statistics to restore the default.
Syntax

Usage guidelines
To include the number of successful matches and matching bytes on an IPv6 policy node in the statistics displayed by a display command, execute this command. As a best practice to conserve hardware resources, disable this counting function.
This apply clause is always executed for the IPv6 policy node.
Examples
# Enable match counting on IPv6 policy node 1.
<Sysname> system-view
[Sysname] ipv6 policy-based-route 1 permit node 1
[Sysname-pbr6-1-1] apply statistics
description

Predefined user roles
network-admin
Parameters
ipv6-acl-number: Specifies an IPv6 ACL by its number in the range of 2000 to 3999. The value range of a basic ACL is 2000 to 2999 and that of an advanced ACL is 3000 to 3999.
name ipv6-acl-name: Specifies an IPv6 ACL by its name, a case-insensitive string of 1 to 63 characters starting with a letter. The ACL name cannot be all. For the command to take effect, make sure the specified IPv6 ACL is a basic or advanced ACL.
Usage guidelines
If the specified ACL does not exist or has no rules configured, no packets will match the ACL.
If the vpn-instance keyword is specified for an ACL rule, the ACL does not take effect. If the vpn-instance keyword is not specified, the rule applies to both public and private network packets.
Examples
# Configure Node 10 of policy aa to permit the packets matching ACL 2000.
<Sysname> system-view
[Sysname] ipv6 policy-based-route aa permit node 10
[Sysname-pbr6-aa-10] if-match acl 2000
# Configure Node 10 of policy aa to permit the packets matching ACL aaa.
[Sysname] ipv6 policy-based-route aa permit node 10
[Sysname-pbr6-aa-10] if-match acl name aaa
ipv6 global policy-based-route
Use ipv6 global policy-based-route to specify a PBR policy as the IPv6 global PBR policy.
Use undo ipv6 global policy-based-route to restore the default.
Syntax
ipv6 global policy-based-route policy-name
undo ipv6 global policy-based-route
Default
No policy is specified for IPv6 global PBR.
Views

Predefined user roles
network-admin
Parameters
policy-name: Specifies a PBR policy by its name, a case-sensitive string of 1 to 19 characters. The specified policy must already exist.
Usage guidelines
IPv6 global PBR guides the forwarding of packets on all interfaces of the device.
You can specify only one policy for IPv6 global PBR on the device. Before you apply a new policy, you must first remove the current policy.
IPv6 interface PBR takes precedence over IPv6 global PBR on an interface. When they are both configured and packets fail to match the IPv6 interface PBR policy, IPv6 global PBR applies.
Examples
# Specify PBR policy aaa for IPv6 global PBR.
<Sysname> system-view
[Sysname] ipv6 global policy-based-route aaa
Related commands
display ipv6 policy-based-route global

Use undo ipv6 local policy-based-route to restore the default.
Syntax

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

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 varies by device model.
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.

Usage guidelines
The IPv6 PBR logging feature helps the administrator locate and fix faults. The feature logs IPv6 PBR events and sends the logs to the information center. The information center processes the logs according to output rules. For more information about the information center, see System Management Configuration Guide.
Excessive IPv6 PBR log messages degrade the performance of the device. To avoid this problem, disable the IPv6 PBR logging feature.
Examples
# Enable the IPv6 PBR logging feature.
