The following commands configure the Source-Active filters.

To specify VRF information, enter the following commands at the MSDP VRF configuration level.

device(config)# router msdp vrf blue device(config-msdp-router-vrf blue)# sa-filter in 2.2.2.99 device(config-msdp-router-vrf blue)# sa-filter in 2.2.2.97 route-map msdp_map device(config-msdp-router-vrf blue)# sa-filter in 2.2.2.96 route-map msdp2_map rp- route-map msdp2_rp_map

The sa-filtercommands configure the following filters:

•sa-filter in 2.2.2.99 - This command drops all source-group pairs received from neighbor 2.2.2.99.

NOTE

The default action is to deny all source-group pairs from the specified neighbor. If you want to permit some pairs, use route maps.

•sa-filter in 2.2.2.97 route-map msdp_map - This command drops source-group pairs received from neighbor 2.2.2.97 if the pairs have source addresses matching 10.x.x.x and group address 235.10.10.1.

•sa-filter in 2.2.2.96 route-map msdp2_map rp-route-map msdp2_rp_map - This command accepts all source-group pairs except those associated with RP 2.2.42.3.

Syntax: [no] sa-filter in originate out ip-addr[route-map map-tag] [rp-route-map rp-map-tag]

Selecting the in option applies the filter to incoming Source-Active messages.

Selecting the originate option applies the filter to self-originated outbound Source-Active messages.

Selecting the out option applies the filter to self-originated and forwarded outbound Source-Active messages.

The ip-addrparameter specifies the IP address of the MSDP neighbor. The filters apply to Source- Active messages received from or sent to this neighbor.

The route-mapmap-tagparameter specifies a route map. The device applies the filter to source-group pairs that match the route map. Use the match ip addressacl-idcommand in the route map to specify an extended ACL that contains the source addresses.

The rp-route-maprp-map-tagparameter specifies a route map to use for filtering based on Rendezvous Point (RP) address. Use this parameter if you want to filter Source-Active messages based on their originating RP. Use the match ip route-sourceacl-idcommand in the route map to specify an extended ACL that contains the RP address.

NOTE

The default filter action is deny. If you want to permit some source-group pairs, use a route map.
