MSDP configuration examples
PIM-SM Inter-domain multicast configuration
Network requirements
• As shown in Figure 62 , AS 100 and AS 200 run OSPF within each AS, and run BGP between each
other.
• 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.
• Loopback 0 is configured as the C-BSR and C-RP of the related PIM-SM domain on Switch B, Switch
C, and Switch E, respectively.
