MSDP configuration examples
This section describes details about MSDP configuration examples.
PIM-SM Inter-domain multicast configuration
Network requirements
As shown in
:
•
There are 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.
•
Configure Loopback 0 as the C-BSR and C-RP of the related PIM-SM domain on Switch B,
Switch C, and Switch E.
Set up MSDP peering relationship between the RPs of the PIM-SM domains to share multicast
source information among the PIM-SM domains.
