Usage Guidelines

Usage Scenario

After the peer as-path-filter import command is used to apply a route filtering policy based on an AS_Path list to BGP routes to be received from a specified peer, the routers that do not match the policy are filtered out.

Prerequisites

The ip as-path-filter command has been run to define an AS-Path filter.

Precautions

Only one AS_Path filter can be used to filter routes to be received from the same peer.

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

Example

# Configure an AS_Path filter for a peer.

<HUAWEI> system-view
[~HUAWEI] ip as-path-filter 3 permit 100
[*HUAWEI] bgp 100
[*HUAWEI-bgp] peer 10.1.1.1 as-number 100
[*HUAWEI-bgp] ipv6-family vpnv6
[*HUAWEI-bgp-af-vpnv6] peer 10.1.1.1 enable
[*HUAWEI-bgp-af-vpnv6] peer 10.1.1.1 as-path-filter 3 import
