Configuration procedure
1. Configure IP addresses and unicast routing:
Configure the IP address and subnet mask for each interface as per
Figure 349 . (Details not
shown.)
Configure OSPF on routers and firewalls in each AS to make sure the network-layer in each AS is
interoperable and routing information among the routers and firewalls can be dynamically
updated. (Details not shown.)
2. Enable IP multicast routing, enable PIM-SM and IGMP, and configure a PIM-SM domain border:
# Enable IP multicast routing on Router A, enable PIM-SM on each interface, and enable IGMP on
the host-side interface GigabitEthernet 0/3.
