IPv6 policy-based routing commands

apply default-next-hop

Use apply default-next-hop to set default next hops.

Use undo apply default-next-hop to remove default next hops.

Syntax

apply default-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 ] ] }&<1-2>

undo apply default-next-hop [ [ vpn-instance vpn-instance-name ] ipv6-address&<1-2> ]

Default

No default next hops are set.

Views

IPv6 policy node view

Predefined user roles

network-admin

Parameters

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance to which the default next hop belongs. The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. If the default next hop belongs to the public network, do not specify this option.

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.

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 default next hop by its index in the range of 1 to 255.

&<1-2>: Indicates that you can specify up to two default next hops.

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.

To set multiple default 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 default-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 default-next-hop command with the service chain parameters and the apply service-chain command.

Examples

# Set a directly-connected default next hop of 1:1::1:1.

<Sysname> system-view

[Sysname] ipv6 policy-based-route aa permit node 11

[Sysname-pbr6-aa-11] apply default-next-hop 1:1::1:1 direct

Related commands

apply loadshare

apply service-chain

apply loadshare

Use apply loadshare to enable load sharing among multiple next hops or default next hops.

Use undo apply loadshare to restore the default.

Syntax

apply loadshare { default-next-hop | next-hop }

undo apply loadshare { default-next-hop | next-hop }

Default

Multiple next hops or default next hops operate in primary/backup mode.

Views

Predefined user roles

network-admin

Parameters

default-next-hop: Enables load sharing among multiple default next hops.

next-hop: Enables load sharing among multiple next hops.

Usage guidelines

Multiple next hop or default next hop options operate in either primary/backup or load sharing mode.

· 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

# Enable load sharing among multiple default next hops.

<Sysname> system-view

[Sysname] ipv6 policy-based-route aa permit node 11

[Sysname-pbr6-aa-11] apply default-next-hop 1::1 2::2

[Sysname-pbr6-aa-11] apply loadshare default-next-hop

Related commands

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.

&<1-8>: Indicates that you can repeat the previous group of parameters to configure up to eight 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.

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.

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 a node in the service chain by its index to match packets sent from that node. The value range for path indexes is 1 to 255. Specify this option if the device might receive packets from different nodes in the service chain. If only one node in the service chain sends packets to the device, you do not need to specify this option.

Examples

# Set a service chain match criterion to match packets with service chain path ID 1 and node index 10.

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

System view

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 ignore policy-based-route dest-local enable

Use ipv6 ignore policy-based-route dest-local enable to enable IPv6 PBR to ignore IPv6 packets destined to the local 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 does not ignore IPv6 packets destined to the local interface.

Views

Interface view

Predefined user roles

network-admin

Usage guidelines

If the device performs forwarding in hardware and a packet destined for it matches an IPv6 PBR policy, IPv6 PBR will execute the apply clauses in the policy, including the clause for forwarding. To prevent IPv6 PBR from mistakenly forwarding the packet to another device, you can configure this command in interface view. Upon receiving a packet destined to any IPv6 addresses of the interface, the device will ignore IPv6 PBR settings and deliver the packet to the CPU.

Examples

# Enable IPv6 PBR to ignore IPv6 packets destined to local interface VLAN-interface 2.

<Sysname> system-view

[Sysname] interface vlan-interface 2

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

ipv6 local policy-based-route

Use ipv6 local policy-based-route to configure IPv6 local PBR based on a specified policy.

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

Syntax

ipv6 local policy-based-route policy-name

undo ipv6 local policy-based-route

Default

No policy is referenced for IPv6 local PBR.

Views

System view

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 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

Related commands

display ipv6 policy-based-route local

ipv6 policy-based-route (interface 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 65535. You can configure a maximum of 256 nodes for a single IPv6 policy.

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.

<Sysname> system-view
