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 ] { ip-address [ direct ] [ track track-entry-number ] }&<1-2>

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

Default

No default 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.

ip-address: Specifies the IP 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-n>: Indicates that the argument before it can be entered up to n times. In Release 6607, you can specify a maximum of two default next hops. In Release 6616 and later, you can specify a maximum of 16 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.

·     In Release 6607, you can specify a maximum of two default next hops.

·     In Release 6616 and later, you can repeat this command to specify a maximum of 16 default next hops.

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.

If you have specified the apply service-chain clause for the policy node, you cannot specify multiple default ECMP next hops for recursive lookup in this command.

Examples

# Set 1.1.1.1 to be a directly connected default next hop.

<Sysname> system-view

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

[Sysname-pbr-aa-11] apply default-next-hop 1.1.1.1 direct

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 a 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 policy node are invalid.

Views

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 policy node are unavailable. To drop all matching packets when all next hops on the 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 policy node, this command drops all packets that match the node.

This command does not apply to software-forwarded packets.

Examples

# Set next hop 1.1.1.1 on policy node 10 and configure the policy node to drop matching packets when the next hop is invalid.

<Sysname> system-view

[Sysname] policy-based-route policy1 permit node 10

[Sysname-pbr-policy1-10] apply next-hop 1.1.1.1

[Sysname-pbr-policy1-10] apply fail-action-drop next-hop

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.

 

 

NOTE:

This command is supported only in Release 6616 and later.

 

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

Policy node view

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—One option is selected from among all options in configuration order for packet forwarding, with all remaining options as backups. If multiple next hops are configured, the first configured next hop is selected. When the selected next hop fails, the next available next hop takes over.

·     Load sharing mode—Multiple options load share traffic in proportion to their weight. By default, all next hops have the same weight and traffic is evenly distributed among them.

Examples

# Enable load sharing among multiple next hops.

<Sysname> system-view

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

[Sysname-pbr-aa-11] apply next-hop 1.1.1.1 2.2.2.2

[Sysname-pbr-aa-11] apply loadshare next-hop

# Enable load sharing among multiple default next hops.

<Sysname> system-view

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

[Sysname-pbr-aa-11] apply default-next-hop 1.1.1.1 2.2.2.2

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.

track track-entry-number: Specifies a track entry by its number in the range of 1 to 1024.

&<1-n>: Indicates that the argument before it can be entered up to n times. In Release 6607, you can specify a maximum of two next hops. In Release 6616 and later, you can specify a maximum of 16 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.

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.

Parameters

policy-name: Specifies a policy by its name, a case-sensitive string of 1 to 19 characters. The specified policy must already exist.

Usage guidelines

Local PBR guides the forwarding of locally generated packets, such as ICMP packets generated by using the ping command.

Local PBR might affect local services, such as ping and Telnet. When you use local PBR, make sure you fully understand its impact on local services of the device.

You can specify only one policy for local PBR and must make sure the specified policy already exists.

Before you apply a new policy, you must first remove the current policy.

Examples

# Configure local PBR based on policy aaa.

<Sysname> system-view

[Sysname] ip local policy-based-route aaa
