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 the OSPF protocol for interoperation among the switches in the PIM-SM domain. Ensure the
network-layer interoperation in the PIM-SM domain and enable dynamic update of routing information
among the switches through a unicast routing protocol. Detailed configuration steps are omitted here.
2) Enable IP multicast routing, and enable PIM-SM and IGMP
# Enable IP multicast routing on Switch A, enable PIM-SM on each interface, and run IGMPv3 on
VLAN-interface 100, which connects Switch A to the stub network.
