To display which interfaces are enabled with PIM-SM, use the show ip pim interface command from EXEC Privilege mode.
Following is an example of show ip pim interface command output:
DellEMC#show ip pim interface
Address Interface Ver/ Nbr Query DR DR
Mode Count Intvl Prio
165.87.34.5 Te 1/10 v2/S 0 30 1 165.87.34.5
10.1.1.2 Vl 10 v2/S 1 30 1 10.1.1.2
20.1.1.5 Vl 20 v2/S 1 30 1 20.1.1.5
165.87.31.200 Vl 30 v2/S 1 30 1 165.87.31.201
DellEMC#show ipv6 pim interface

DR : this router
Te 1/3 v2/S 0 30 1

DR : this router
NOTE: You can influence the selection of the Rendezvous Point by enabling PIM-Sparse mode on a Loopback interface
and assigning a low IP address.
To display PIM neighbors for each interface, use the show ip pim neighbor [detail] command EXEC Privilege mode.
Following is an example of show ip pim neighbor command output:
DellEMC#show ip pim neighbor
Neighbor Interface Uptime/Expires Ver DR
Address Prio/Mode

To display the PIM routing table, use the show ip pim tib [group-address [source-address]] command from EXEC
privilege mode.
Following is an example of show ip pim tib command output:
DellEMC#show ip pim tib
