Parameters

Parameter	Description	Value
ipv6-address	Specifies the IPv6 address of a peer.	The prefix is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X.
acl6-number	Specifies the number of a basic ACL.	The value is an integer ranging from 2000 to 2999.
acl6-name acl6-name	Specifies the name of a named basic ACL6.	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).

Parameter

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 IPv6 filtering policy for peers.

<HUAWEI> system-view
[~HUAWEI] acl ipv6 2001
[*HUAWEI-acl6-basic-2001] rule permit
[*HUAWEI-acl6-basic-2001] quit
[*HUAWEI] bgp 100
[*HUAWEI-bgp] peer 2001:db8::3:4 as-number 200
[*HUAWEI-bgp] ipv6-family unicast
[*HUAWEI-bgp-af-ipv6] peer 2001:db8::3:4 enable
[*HUAWEI-bgp-af-ipv6] peer 2001:db8::3:4 filter-policy 2001 export
