Enable PIM-SM
You must enable PIM-SM on each participating interface.
1. Enable IPv4 multicast routing on the system.
CONFIGURATION mode
ip multicast-routing [vrf vrf-name]
2. Enable PIM-Sparse mode.
INTERFACE mode
ip pim sparse-mode
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 Tf 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
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
127.87.5.5 Tf 1/11 01:44:59/00:01:16 v2 1 / S

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
