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.

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 output-interface

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 ] [ service-chain path-id service-path-id [ path-index service-path-index ] ] } &<1-6>

undo apply next-hop [ [ vpn-instance vpn-instance-name ] ipv6-address&<1-6> ]

Default

No next hops are 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.

service-chain path-id service-path-id: Specifies a service chain by its path ID. A path ID uniquely identifies a service chain, and its value range is 1 to 16777215.

path-index service-path-index: Specifies a node in the service chain as a next hop by its index in the range of 1 to 255.

&<1-6>: Indicates that the argument before it can be entered up to six 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.

To set multiple next hops and specify their service chain parameters (service chain path ID and node index), follow these guidelines:

·     If the next hops are used in different service chains, use the apply next-hop command to specify the service chain parameters.

·     If the next hops are used in the same service chain, use the apply service-chain command to specify the service chain parameters as a best practice.

·     On an IPv6 policy node, you cannot configure both the apply next-hop command with the service chain parameters and the apply service-chain command.

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

Without any output interface specified, the undo apply output-interface command removes all output interfaces.

Examples

# Specify VLAN-interface 2 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 vlan-interface 2

apply service-chain

Use apply service-chain to set service chain information.

Use undo apply service-chain to restore the default.

Syntax

apply service-chain path-id service-path-id [ path-index service-path-index ]

Parameters

path-id service-path-id: Specifies a service chain by its path ID in the range of 1 to 16777215. The path ID uniquely identifies a service chain.

path-index service-path-index: Specifies the path index of the node to which you are sending the matching packets. The value range for path indexes is 1 to 255. Specify this option if the destination node might receive packets from different nodes in the service chain. If the destination node receives packets only from the device, you do not need to specify this option.

Examples

# Set service chain path ID 1 and node index 10.

<Sysname> system-view

[Sysname] ipv6 policy-based-route aa permit node 5

[Sysname-pbr6-aa-5] apply service-chain path-id 1 path-index 10

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

ipv6 policy-based-route

ipv6 ignore policy-based-route dest-local enable

Use ipv6 ignore policy-based-route dest-local enable to disable IPv6 PBR from processing packets destined for an IPv6 address of the interface.

Use undo ipv6 ignore policy-based-route dest-local enable to restore the default.

Syntax

ipv6 ignore policy-based-route dest-local enable

undo ipv6 ignore policy-based-route dest-local enable

Default

IPv6 PBR processes packets destined for an IPv6 address of the interface.

Views

Interface view

Predefined user roles

network-admin

Usage guidelines

This command is supported in Release 6530P01 and later.

When an interface receives a packet destined for an IPv6 address of itself, the interface matches the packet against the IPv6 PBR policies. If the packet matches a node in a policy, IPv6 PBR will execute the action specified by the node on the packet before sending the packet to the CPU. To enable the interface to directly send the packet to the CPU without executing the PBR action, execute this command on the interface. This command prevents IPv6 PBR from sending packets destined for the local device to other devices by mistake.

Examples

# On VLAN-interface 2, disable IPv6 PBR from processing packets destined for an IPv6 address of the interface.

<Sysname> system-view

[Sysname] interface vlan-interface 2

[Sysname-Vlan-interface2] ipv6 ignore policy-based-route dest-local enable

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 is 0 to 255.

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.
