Configuration procedure
1 Configure interface IP addresses and unicast routing protocol on the switches.
In each PIM-SM domain, configure the interface IP addresses on the switches and
interconnect the switches through OSPF. Make sure that Switch A, Switch B and
Switch C in the PIM-SM 1 domain are interoperable on the network layer, Switch
D and Switch E in the PIM-SM 2 domain are interoperable on the network layer,
and Switch F and Switch G in the PIM-SM 3 domain are interoperable on the
network layer. On the other hand, switches in each PIM-SM domain can update
routes dynamically by using unicast routing protocols. Configure the IP address
and mask of each interface according to Figure 124. The details are omitted here.
2 Enable multicast and enable PIM-SM on each interface.
# Enable multicast on SwitchC and enable PIM-SM on all interfaces. Switch C is
taken for example. The configuration procedures on other switches are similar to
that on Switch C. The details are omitted here.
