Configuring MSDP
Controlling Source Information that Your Switch Forwards
By default, the switch forwards all SA messages it receives to all its MSDP peers. However, you can prevent outgoing
messages from being forwarded to a peer by using a filter or by setting a time-to-live (TTL) value. These methods are
described in the next sections.
Using a Filter
By creating a filter, you can perform one of these actions:
Filter all source/group pairs
Specify an IP extended access list to pass only certain source/group pairs
Filter based on match criteria in a route map
Follow this procedure to apply a filter. This procedure is optional.
