PIM-SM Inter-domain multicast configuration
Network requirements
As shown in Figure 54, the network has two OSPF ASs: AS 100 and AS 200. BGP runs between the two
ASs.
PIM-SM 1 belongs to AS 100, and PIM-SM 2 and PIM-SM 3 belong to AS 200. Each PIM-SM domain
has at least one multicast source or receiver.
