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.

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.<HUAWEI> system-view [~HUAWEI] acl ipv6 2001 [*HUAWEI-acl6-basic-2001] rule permit [*HUAWEI-acl6-basic-2001] quit [*HUAWEI] bgp 100 [*HUAWEI-bgp] peer 10.1.1.1 as-number 200 [*HUAWEI-bgp] ipv6-family unicast [*HUAWEI-bgp-af-ipv6] peer 10.1.1.1 enable [*HUAWEI-bgp-af-ipv6] peer 10.1.1.1 filter-policy 2001 export
