MSDP configuration examples
This section provides examples of configuring MSDP on routers.
PIM-SM inter-domain multicast configuration
Network requirements
As shown in Figure 53:
OSPF runs within AS 100 and AS 200. BGP runs between the two ASs.
Each PIM-SM domain has a minimum of one multicast source or receiver.
Set up MSDP peering relationships between the RPs in the PIM-SM domains to share multicast
source information among the PIM-SM domains.
