Multicast Source Discovery Protocol (MSDP)

Example

The following commands configure an IP address on port 3/1. This is the port on which the MSDP
neighbors will be configured.

TurboIron(config)#interface ethernet 3/1

TurboIron(config-if-3/1)#ip address 2.2.2.98/24

TurboIron(config-if-3/1)#exit

The following commands configure a loopback interface. The Layer 3 Switch will use this interface
as the source address for communicating with the MSDP neighbors.

TurboIron(config)#interface loopback 1

TurboIron(config-lbif-1)#ip address 9.9.9.8/32

TurboIron(config-lbif-1)#exit

The following command configures an extended ACL to specify the source and group addresses you
want to filter.

TurboIron(config)#access-list 123 permit 10.0.0.0 0.255.255.255 any

The following commands configure a route map. The map matches on source address 10.x.x.x and
any group address. Since the action is deny, the Source-Active filter that uses this route map will
remove the source-group pairs that match this route map from the Source-Active messages to the
neighbor.

TurboIron(config)#route-map msdp_map deny 1

TurboIron(config-routemap msdp_map)#match ip address 123

TurboIron(config-routemap msdp_map)#exit

The following commands enable MSDP and configure MSDP neighbors.

TurboIron(config)#router msdp

TurboIron(config-msdp-router)#msdp-peer 2.2.2.99 connect-source loopback 1

TurboIron(config-msdp-router)#msdp-peer 2.2.2.97 connect-source loopback 1

TurboIron(config-msdp-router)#exit

The following commands configure the Source-Active filter.

TurboIron(config)#router msdp

TurboIron(config-msdp-router)#sa-filter originate route-map msdp_map

This filter removes source-group pairs that match route map msdp_map from Source-Active
messages before sending them to MSDP neighbors.

CLI syntax
Syntax: [no] sa-filter originate [route-map ]

The route-map parameter specifies a route map. The Layer 3 Switch applies the filter to
source-group pairs that match the route map. Use the match ip address acl-id command in the
route map to specify an extended ACL that contains the source and group addresses.

NOTE

The default filter action is deny. If you want to permit some source-group pairs, use a route map. A
permit action in the route map allows the Layer 3 Switch to receive the matching source-group pairs.
A deny action in the route map drops the matching source-group pairs.
