MSDP Configuration Examples
Inter-AS Multicast Configuration Leveraging BGP Routes
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.
