import route-policy

import route-policy

Function

The import route-policy command associates the current VPN instance address family with an import Route-Policy.

The undo import route-policy command disassociates the current VPN instance address family from an import Route-Policy.

By default, the current VPN instance address family is not associated with any import Route-Policy.

NOTE:

CE6810LI series do not support this command.

Format

import route-policy policy-name

VPN instance view:

undo import route-policy

VPN instance IPv4 address family view:

undo import route-policy [ policy-name ]

Parameters

Parameter Description Value
policy-name Specifies the name of the import Route-Policy to be associated with the VPN instance address family. The name is a string of 1 to 200 case-sensitive characters except spaces. When double quotation marks are used to include the string, spaces are allowed in the string.

Views

VPN instance view, VPN instance IPv4 address family view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

When no import Route-Policy is configured, routes that match the export VPN target attribute of the received routes and the import VPN target attribute of the local VPN instance address family are added to the VPN instance address family. To control the import of the routes into the VPN instance address family more accurately, you can use the import Route-Policy. The import Route-Policy is used to filter the imported routing information and to set the routing attributes of the routes that pass the filtering.

The import route-policy command controls the VPN routes that are cross added to the VPN instance address family. The peer route-policy command or the filter-policy command run in the BGP VPN instance address family view filters routes of the VPN instance address family advertised to or received from CE neighbors.

Prerequisites

The route-distinguisher command has been executed to set the RD of the VPN instance.

Precautions

The current VPN instance address family can be associated with only one import Route-Policy. If the import route-policy command is run several times, the latest configuration overrides the previous configurations.

If the route policy to be associated with the VPN instance address family does not exist, you need to configure the route policy.

Example

# Apply an import Route-Policy named poly-1 to the IPv4 address family of the VPN instance named vrf1.

<HUAWEI> system-view
[~HUAWEI] ip vpn-instance vrf1
[*HUAWEI-vpn-instance-vrf1] ipv4-family
[*HUAWEI-vpn-instance-vrf1-af-ipv4] route-distinguisher 100:1
[*HUAWEI-vpn-instance-vrf1-af-ipv4] import route-policy poly-1
