Figure 204 Network diagram for inter-AS multicast configuration leveraging static RPF
peers
Configuration procedure
1 Configure the interface IP addresses and unicast routing protocol for each switch
Configure the IP address and subnet mask for each interface as per Figure 204.
Detailed configuration steps are omitted here.
Configure OSPF for interconnection between the switches. Ensure the
network-layer interoperation in each AS, and ensure the dynamic update of
routing information among the switches through a unicast routing protocol.
Detailed configuration steps are omitted here.
2 Enable IP multicast routing, enable PIM-SM and IGMP, and configure a PIM-SM
domain border
# Enable IP multicast routing on Switch A, enable PIM-SM on each interface, and
enable IGMP on the host-side interface VLAN-interface 200.
