peer ip-prefix export (BGP-IPv4 multicast address family view)

Usage Scenario

The peer ip-prefix export command can be used to configure a route filtering policy that is based on an IP prefix list for filtering BGP routes to be advertised to a specified peer, implementing route control.

Prerequisites

If the peer ip-prefix command specifies an IP prefix list that does not exist for a peer, use the ip ip-prefix command to create an IP prefix list.

Configuration Impact

If an IP prefix list is specified for a peer group, all the members of the peer group inherit the configuration.

After an IP prefix list is specified for a peer, the peer filter the routes to be advertised to other peers based on the IP prefix list. Only the routes that pass the filtering of the IP prefix list can be advertised.

Precautions

If both this command and the peer route-filter export command are run, the latest configuration overrides the previous one.

If the length of the filter name is less than or equal to six characters and the name matches the first six characters of export or import, When you run the undo command, the filter name cannot be entered. You only need to enter the keyword import or export.
