Step 3 Configure the interfaces connected to hosts to be PIM silent and configure IGMP on the interface.
# On Switch A, configure the vlanif interfaces connected to hosts to be PIM silent, and configure
IGMP on the interface. The configurations of Switch B, Switch C, and Switch D are similar to
configuration of Switch A, and are not provided here.
[SwitchA] interface vlanif 101
[SwitchA-Vlanif101] pim silent
[SwitchA-Vlanif101] igmp enable
[SwitchA-Vlanif101] quit
Step 4 Verify the configuration.
# Run the display pim interface command to view the configuration and operating of PIM on
the router interface. The display of the PIM configuration on Switch D is as follows:
[SwitchD] display pim interface
VPN-Instance: public net

# Run the display pim neighbor command to check the PIM neighbor relationship between the
switches. The display of the PIM neighbor relationship on Switch D is as follows:
[SwitchD] display pim neighbor

# Run the display pim routing-table command to view the PIM multicast routing table on the
switch. Assume that HostA needs to receive the information about multicast group G
225.1.1.1/24. When sending multicast packets to multicast group G, multicast source S
10.110.5.100/24 generates an SPT through flooding and the (S, G) entries exist on Switch A and
Switch D that are in the SPT. When HostA joins multicast group G, an (*, G) entry is generated
on Switch A. The information displayed on Switch B and Switch C is similar to the information
displayed on Switch A. The displayed information is as follows:
[SwitchA] display pim routing-table
VPN-Instance: public net
Total 1 (*, G) entry; 1 (S, G) entry
(*, 225.1.1.1)
(10.110.5.100, 225.1.1.1)
