Network diagram
Figure 203 Network diagram for inter-AS multicast configuration leveraging BGP routes
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 203.
Detailed configuration steps are omitted here.
Configure OSPF for interconnection between switches in each AS. Ensure the
network-layer interoperation among each AS, and ensure the dynamic update of
routing information between the switches through a unicast routing protocol.
Detailed configuration steps are omitted here.
2 Enable IP multicast routing, enable PIM-SM on each interface, 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.
