MBGP Configuration Example
Network requirements
As shown in the following figure:
z PIM-SM 1 is in AS 100 and PIM-SM 2 is in AS 200. OSPF is the IGP in the two ASs, and MBGP
runs between the two ASs to exchange multicast route information.
z The multicast source belongs to PIM-SM 1, and the receiver belongs to PIM-SM 2.
z It is required that the respective Loopback 0 of Switch A and Switch B be configured as the
C-BSR and C-RP of the respective PIM-SM domains.
z Router A and Router B establishes an MSDP peer relationship through MBGP.

Configuration procedure
1) Configure IP addresses for interfaces as shown in the above figure (omitted).
2) Configure OSPF (omitted).
3) Enable IP multicast routing, PIM-SM and IGMP, and configure a PIM-SM domain border.
# Enable IP multicast routing on Switch A, and enable PIM-SM on each interface.
