SA Request Processing
    
        
            You can configure the router to accept or reject SA request
                messages from a specified MSDP (Multicast Source Discovery Protocol) peer or all peers. If an
                SA request filter is specified, only SA request messages from those groups permitted
                are accepted. All others are ignored.

enable msdp [{peer} remoteaddr | peer
                        all] process-sa-request {sa-request-filter
                        filter-name } {vr
                        vr_name}
