Configuration procedure
1) Configure
IP
addresses and unicast routing
Configure the IP address and subnet mask for each interface as per
. 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.
