I suppose that would depend on the topology design. But if it's your hub,
I'd say yes.
The pim nbma mode is a sub-interface command, although its classification of
things will affect how the physical interface/hardware queues handle the
traffic.

Ok,
If I have the following scenario running multicast, should I enable "ip pim
nbma" on the main interface, on sub-interfaces or All interface?
interface Serial 0/0
encapsulation frame-relay
ip pim nbma <-?
!
interface Serial 0/0.1 multipoint
description Connect to RP
ip pim nbma <-?
!
interface Serial 0/0.2 multipoint
description Connect to Router running "ip igmp join-group"
ip pim nbma <-?
!
If there is only one hardware broadcast queue, only main interface should be
applied? I'm really in lose.
Thanks !
Ryan
