apply access-vpn vpn-instance

Use apply access-vpn vpn-instance to set a VPN instance.

Use undo apply access-vpn vpn-instance to remove the specified VPN instance.

Syntax

apply access-vpn vpn-instance vpn-instance-name

undo apply access-vpn vpn-instance [ vpn-instance-name ]

Default

No VPN instance is specified for a node.

Parameters

vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. The specified VPN must already exist.

Usage guidelines

With a VPN instance specified, the undo apply access-vpn vpn-instance command removes the VPN instance.

Without any VPN instance specified, the undo apply access-vpn vpn-instance command removes all VPN instances.

Examples

# Set VPN 1 for node 10. (VPN 1 already exists.)

<Sysname> system-view

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

[Sysname-pbr-policy1-10] apply access-vpn vpn-instance vpn1

apply next-hop

Use apply next-hop to set a next hop.

Use undo apply next-hop to remove the configuration.

Syntax

apply next-hop [ vpn-instance vpn-instance-name ] { ip-address [ direct ] [ track track-entry-number ] }&<1-2>

undo apply next-hop [ [ vpn-instance vpn-instance-name ] ip-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 must already exist.

ip-address: Specifies the IP 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.

&<1-2>: Indicates that the argument before it can be entered twice at most.

Usage guidelines

You can specify at most two next hops for backup in one command line or by executing this command twice. The first next hop configured is the active next hop and the second is the standby next hop.

With two next hops specified, only the active next hop takes effect. When the active next hop is not available, the standby next hop takes effect. When neither next hop is available, packets are forwarded according to the routing table.

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 1.1.1.1.

<Sysname> system-view

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

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

apply output-interface

Use apply output-interface to set an output interface.

Use undo apply output-interface to remove the configuration.

Syntax

apply output-interface { interface-type interface-number [ track track-entry-number ] }

undo apply output-interface [ { interface-type interface-number } ]

Default

No output interface is set.

Parameters

interface-type interface-number: Specifies an interface by its type and number. Only null interfaces are supported.

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

Usage guidelines

With an output interface specified, the undo apply output-interface command removes the output interface.

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

Examples

# Specify NULL 0 as the output interface for IP packets.

<Sysname> system-view

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

[Sysname-pbr-aa-11] apply output-interface null 0

apply precedence

Use apply precedence to set a precedence for IP packets.

Use undo apply precedence to restore the default.

Syntax

apply precedence { type | value }

undo apply precedence

Default

No precedence is set for IP packets.

Field	Description
Policy based routing information for interface Vlan-interface100	PBR configuration and statistics on VLAN-interface 100. failed indicates that the policy (including all its nodes) failed to be assigned to the driver. For a global interface (with only a one-dimensional interface number, for example, VLAN-interface 10), failed can be displayed only when you specify the slot slot-number or chassis chassis-number slot slot-number option for the command.
node 0 permit	Match mode of the node, permit or deny. not support means the device does not support match criteria configured on the node; no resource means the device has insufficient ACL resources, and failed to assign ACL resources to the node. For a global interface (with only a one-dimensional interface number, for example, VLAN-interface 10), not support and no resource can be displayed only when you specify the slot slot-number or chassis chassis-number slot slot-number option for the command.
if-match acl	Matches packets against the ACL.
apply next-hop	Specify a next hop for permitted packets.
apply output-interface NULL 0	Specify an output interface for permitted packets.
Matched: 0	Number of successful matches on the node (no statistics resource indicates insufficient statistics resources). For a global interface (with only a one-dimensional interface number, for example, VLAN-interface 10), no statistics resource can be displayed only when you specify the slot slot-number or chassis chassis-number slot slot-number option for the command.
Total matched	Total number of successful matches on all nodes.

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 is used to route locally generated packets. This feature might affect local services, such as ping and Telnet. Do not configure local PBR unless doing so is required.

Examples

# Configure local PBR based on policy aaa.

<Sysname> system-view

[Sysname] ip local policy-based-route aaa
