6.7 MSDP Configuration Examples
6.7.1 Inter-AS Multicast Configuration Leveraging BGP Routes
I. Network requirements
z There are two ASs in the network, AS 100 and AS 200 respectively. OSPF is
running within each AS, and BGP is running between the two ASs.
z PIM-SM 1 belongs to AS 100, while PIM-SM 2 and PIM-SM 3 belong to AS 200.
z Each PIM-SM domain has zero or one multicast source and receiver. OSPF runs
within each domain to provide unicast routes.
z It is required that the respective Loopback 0 of Switch B, Switch C and Switch E be
configured as the C-BSR and C-RP of the respective PIM-SM domains.
z It is required that an MSDP peering relationship be set up between Switch B and
Switch C through EBGP, and between Switch C and Switch E through IBGP.
