Step 2
show ip pim interface type number
Use this command to display information about interfaces configured for PIM.
The following is sample output from the show ip pim interface command:
Example:
Device# show ip pim interface GigabitEthernet 1/0/0
Address Interface Ver/ Nbr Query DR DR
Mode Count Intvl Prior
