peer filter-policy import (BGP-VPN instance IPv4 address family view)

Function

The peer filter-policy import command configures an ACL-based policy for filtering BGP routes received from a specified peer.

The undo peer filter-policy import command cancels this configuration.

By default, no filtering policy is set for a peer.

Format

peer ipv4-address filter-policy acl-number import

peer ipv4-address filter-policy acl-name acl-name import

undo peer ipv4-address filter-policy acl-number import

undo peer ipv4-address filter-policy acl-name acl-name import

Parameters

Parameter	Description	Value
ipv4-address	Specifies the IPv4 address of a peer.	It is in dotted decimal notation.
acl-number	Specifies the number of a basic ACL.	The value is an integer ranging from 2000 to 2999.
import	Filters received routes.	-
acl-name acl-name	Specifies the name of a named basic ACL.	The value is a string of 1 to 64 case-sensitive characters without spaces. The value must start with a letter (a to z or A to Z, case sensitive).

Usage Guidelines

Usage Scenario

The peer filter-policy import command is used to configure an ACL-based policy for filtering routes to be received from peers.

A proper basic ACL needs to be selected based on the address family of a peer.

Configuration Impact

If the peer filter-policy import command is run multiple times, the latest configuration overwrites the previous one.

Precautions

When the rule command is run to configure rules for a named ACL, only the source address range specified by source and the time period specified by time-range take effect.

The peer route-filter import command is mutually exclusive with the peer route-filter import commands.

Example
