Configuring 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.
BigIron RX(config)# interface ethernet 3/1
BigIron RX(config-if-e1000-3/1)# ip address 2.2.2.98/24
BigIron RX(config-if-e1000-3/1)# exit
The following commands configure a loopback interface. The device will use this interface as the
source address for communicating with the MSDP neighbors.
BigIron RX(config)# interface loopback 1
BigIron RX(config-lbif-1)# ip address 9.9.9.8/32
BigIron RX(config-lbif-1)# exit
The following commands configure extended ACLs. The ACLs will be used in route maps, which will
be used by the Source-Active filters.
BigIron RX(config)# access-list 124 permit ip 10.0.0.0 0.255.255.255 any
BigIron RX(config)# access-list 124 permit ip host 2.2.2.2 any
BigIron RX(config)# access-list 125 permit ip any any
The following commands configure the route maps.
BigIron RX(config)# route-map msdp_map deny 1
BigIron RX(config-routemap msdp_map)# match ip address 123
BigIron RX(config-routemap msdp_map)# exit
BigIron RX(config)# route-map msdp2_map permit 1
BigIron RX(config-routemap msdp2_map)# match ip address 125
BigIron RX(config-routemap msdp2_map)# exit
BigIron RX(config)# route-map msdp2_rp_map deny 1
BigIron RX(config-routemap msdp2_rp_map)# match ip route-source 124
BigIron RX(config-routemap msdp2_rp_map)# exit
The following commands enable MSDP and configure the MSDP neighbors on port 3/1.
BigIron RX(config)# router msdp
BigIron RX(config-msdp-router)# msdp-peer 2.2.2.99 connect-source loopback 1
BigIron RX(config-msdp-router)# msdp-peer 2.2.2.97 connect-source loopback 1
BigIron RX(config-msdp-router)# msdp-peer 2.2.2.96 connect-source loopback 1
BigIron RX(config-msdp-router)# exit
The following commands configure the Source-Active filters.
BigIron RX(config)# router msdp
BigIron RX(config-msdp-router)# sa-filter in 2.2.2.99
BigIron RX(config-msdp-router)# sa-filter in 2.2.2.97 route-map msdp_map
BigIron RX(config-msdp-router)# sa-filter in 2.2.2.96 route-map msdp2_map
rp-route-map msdp2_rp_map
The sa-filter commands configure the following filters:
•
626
sa-filter in 2.2.2.99 – This command filters the DUT from local processing and 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.
