The configuration on Firewall B and Firewall C is similar to that on Firewall A.
# Enable IP multicast routing on Firewall D, and enable PIM-DM on each interface.

3. 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 Firewall D.
[FirewallD] display pim interface
VPN-Instance: public net
Interface NbrCnt HelloInt DR-Pri DR-Address
GE0/0 0 30 1 10.110.5.1 (local)
GE0/3 1 30 1 192.168.1.2 (local)
GE0/1 1 30 1 192.168.2.2 (local)
GE0/2 1 30 1 192.168.3.2 (local)
Carry out the display pim neighbor command to view the PIM neighboring relationships among the
firewalls. For example:
# Verify the PIM neighboring relationships on Firewall D.
[FirewallD] display pim neighbor
VPN-Instance: public net
Total Number of Neighbors = 3

Assume that Host A needs to receive the information addressed to multicast group G (225.1.1.1). After the
multicast source S (10.110.5.100/24) sends multicast packets to the multicast group G, an SPT is
established through traffic flooding. Firewalls on the SPT path (Firewall A and Firewall D) have their (S,
G) entries. Host A sends an IGMP report to Firewall A to join the multicast group G, and a (*, G) entry
is generated on Firewall A. You can use the display pim routing-table command to view the PIM routing
table information on each firewall. For example:
