Configuration procedure
1 Configure the interface IP addresses and unicast routing protocols for each switch
Configure interface IP addresses for each switch, and configure OSPF for
interconnection between switches in each PIM-SM domain. Ensure the
network-layer interoperation among switches in PIM-SM1, the network-layer
interoperation between switches in PIM-SM2, and the network-layer
interoperation between switches in PIM-SM3, and ensure the dynamic update of
routing information between the switches in each PIM-SM domain is implemented
through a unicast routing protocol. Configure the IP address and subnet mask for
each interface as shown in Figure 126. The detailed configuration steps are
omitted.
2 Enable multicast and enable PIM-SM on each interface.
# Enable multicast on all the switches, and enable PIM-SM on each interface. The
configuration procedures on the other switches are similar to the configuration
procedure on Switch C. So the configuration procedures on the other switches are
omitted.
