Figure 48-3 Network Topology for MSDP Entry
Configuration tasks are listed as below:
Prerequisites:
Enable the single cast routing protocol and PIM protocol on every router, and make sure that the inter-domain
routing works well and multicasting inside the domain works well.
Suppose the multicast server S in Domain A offers multicast programs at 224.1.1.1. A host in Domain C
named R subscribes this program. Before MSDP is configured C cannot subscribe the multicast program.
However, with the following configuration, R is able to receive programs offered by S.
RP1 in Domain A:
Switch#config
Switch(config)#interface vlan 1
Switch(Config-if-Vlan1)#ip address 10.1.1.1 255.255.255.0
Switch(Config-if-Vlan1)#exit
Switch(config)#router msdp
Switch(router-msdp)#peer 10.1.1.2
Router A in Domain A:
Switch#config
Switch(config)#interface vlan 1
Switch(Config-if-Vlan1)#ip address 10.1.1.2 255.255.255.0
Switch(Config-if-Vlan1)#exit
Switch(config)#interface vlan 2
Switch(Config-if-Vlan2)#ip address 20.1.1.2 255.255.255.0
Switch(Config-if-Vlan2)#exit
Switch(config)#router msdp
Switch(router-msdp)#peer 10.1.1.1
Switch(msdp-peer)#exit
