Associating an interface with PIM doesn't necessarily enable PIM on that interface. To enable PIM over an interface, you must configure a PIM query interval (see Configuring PIM Query Intervals).
This example associates VLAN 5 to PIM 1.
SEFOS# configure terminal SEFOS(config)# set ip pim enable
SEFOS(config)# interface vlan 5
SEFOS(config-if)# ip pim componentId 1 SEFOS(config-if)# end
SEFOS# show ip pim interface detail Vlan5 33 is up Internet Address is 10.1.0.1 Muticast Switching : Enabled PIM : Enabled PIMv6 : Disabled PIM version : 2, mode: Sparse PIM DR : 10.1.0.1 PIM DR Priority : 1 PIM Neighbour Count : 0 PIM Hello/Query Interval : 30 PIM Message Interval : 60 PIM Override Interval : 0 PIM Lan Delay : 0 PIM Lan-Prune-Delay : Disabled PIM Component Id : 1 PIM domain border : enabled
