> (Q1)Guys do we have to use ip pim nbma command on multicast over frame cloud.
yes, but only on the hub router of the frame-relay cloud, not on the spokes

not really necessary to use it for sparse-dense mode
> (Q3)If you use auto-rp, you need a dense mode component(sparse dense mode) for rp candidate to talk to mapping agent. When mapping agent is configured on the hub router(of NBMA) and if RP candidates are configured on the spokes what is the pim mode to configure on the frame cloud(Do we have to create a loopback on the rp candidate and enable sparse-dense mode)
if you are using auto-rp, you will need to use sparse-dense mode over the frame-cloud. You do not have to create a loopback, you can use an Ethernet interface, but you must enable sparse-dense mode on the Ethernet interface. If you do create a loopback interface, you should enable sparse-dense mode on that interface
> (Q4.)What is the easiest way do determine that we need static mroute command on the multicast routers.
Watch for the RPF check, make sure that the multicast traffic is flowing in the direction that you want it to.If it is not, then you should use an mroute
HTH! :-)
