The configuration on Switch B and Switch C is similar to that on Switch A. The
configuration on Switch D and Switch E is also similar to that on Switch A except
that it is not necessary to enable IGMP on the corresponding interfaces on these
two switches.

# Configure the service scope of RP advertisements and the positions of the C-BSR
and C-RP on Switch E.

4 Verify the configuration
Carry out the display pim interface command to view the PIM configuration and
running status on each interface. For example:
# View the PIM configuration information on Switch A.
[SwitchA] display pim interface
Interface NbrCnt HelloInt DR-Pri DR-Address
Vlan100 0 30 1 10.110.1.1 (local)
Vlan101 1 30 1 192.168.1.2
Vlan102 1 30 1 192.168.9.2
To view the BSR election information and the locally configured C-RP information
in effect on a switch, use the display pim bsr-info command. For example:
# View the BSR information and the locally configured C-RP information in effect
on Switch A.
[SwitchA] display pim bsr-info
