peer filter-policy export (BGP-IPv4 unicast address family view)

Function

The peer filter-policy export command configures an ACL-based policy for filtering BGP routes to be advertised to a specified peer.

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

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

Format

peer ipv4-address filter-policy acl-number export

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

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

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

Parameters

Parameter Description Value
ipv4-address

Specifies the IPv4 address of a peer.

It is in dotted decimal notation.

export

Filters routes to be advertised.

Usage Guidelines

Usage Scenario

The peer filter-policy export command is used to configure an ACL-based policy for filtering routes to be advertised to peers.

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

Configuration Impact

If the peer filter-policy export 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 export command is mutually exclusive with the peer route-filter export commands.

Example

# Set the filtering policy for peers.
<HUAWEI> system-view
[~HUAWEI] acl 2001
[*HUAWEI-acl4-basic-2001] rule permit
[*HUAWEI-acl4-basic-2001] quit
[*HUAWEI] bgp 100
[*HUAWEI-bgp] peer 10.1.1.1 as-number 200
[*HUAWEI-bgp] peer 10.1.1.1 filter-policy 2001 export
