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.
3) Configure a C-BSR and a C-RP
# On Switch D, configure the service scope of RP, specify a C-BSR and a C-RP, and set the
hash mask length to 32 and the priority of the C-BSR to 10.
<SwitchD> system-view
[SwitchD] acl number 2005
[SwitchD-acl-basic-2005] rule permit source 225.1.1.0 0.0.0.255
[SwitchD-acl-basic-2005] quit

[SwitchD-pim] quit
# On Switch E, configure the service scope of RP advertisements, specify a C-BSR and a C-RP;
and set the hash mask length to 32 and the priority of the C-BSR to 20.
<SwitchE> system-view

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
