MBGP configuration example
IMPORTANT:
By default, Ethernet interfaces, VLAN interfaces, and aggregate interfaces are in the state of DOWN. To
configure such an interface, use the undo shutdown command to bring it up first.
Network requirements
As shown in Figure 63 , 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. The multicast source
belongs to PIM-SM 1, and the receiver belongs to PIM-SM 2. Configure the respective Loopback 0 of
Switch A and Switch B as the C-BSR and C-RP of the respective PIM-SM domains. Set up an MSDP peer
relationship between Router A and Router B through MBGP.
