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
