R3303-HP HSR6800 Routers IP Multicast Configuration Guide

Use the display pim interface command to display the PIM information on each interface. For
example:
# Display PIM configuration information on Router A.
[RouterA] display pim interface
VPN-Instance: public net
Interface NbrCnt HelloInt DR-Pri DR-Address
GE2/1/0 0 30 1 10.110.1.1 (local)
GE2/1/3 1 30 1 192.168.1.2
GE2/1/1 1 30 1 192.168.9.2
Assume that Host A needs to receive the information a specific multicast source S
(10.110.5.100/24) sends to multicast group G (232.1.1.1). Router A builds an SPT toward the
multicast source. Routers on the SPT path (Router A and Router D) have generated (S, G) entry, but
Router E, which is not on the SPT path, does not have multicast routing entries. You can use the
display pim routing-table command to display the PIM routing table information on each router.
For example:
# Display PIM routing table information on Router A.
[RouterA] display pim routing-table
VPN-Instance: public net
Total 0 (*, G) entry; 1 (S, G) entry
(10.110.5.100, 232.1.1.1)
Protocol: pim-ssm, Flag:
UpTime: 00:13:25
Upstream interface: GigabitEthernet2/1/3
Upstream neighbor: 192.168.1.2
RPF prime neighbor: 192.168.1.2
Downstream interface(s) information:
Total number of downstreams: 1
1: GigabitEthernet2/1/0
Protocol: igmp, UpTime: 00:13:25, Expires: 00:03:25
The information on Router B and Router C is similar to that on Router A.
# Display PIM routing table information on Router D.
[RouterD] display pim routing-table
VPN-Instance: public net
Total 0 (*, G) entry; 1 (S, G) entry
(10.110.5.100, 232.1.1.1)
Protocol: pim-ssm, Flag: LOC
