To view if a PIM router interface is the DR for the LAN segment, enter the following command:

-> show ip pimsm neighbor

Neighbor Address  Vlan     Uptime      Expires     Mode
-----------------+--------+-----------+-----------+---------
192.168.11.2      2        17h:49m:48s 00h:01m:28s Sparse (DR)
192.168.12.2      2        17h:19m:34s 00h:01m:15s Sparse (DR)

If (DR) is not present it means the interface has not DR role on the segment.
