Hello Tony
From my understanding the ip pim nbma mode would only affect for groups that
are in sparse.
If you come to the situation that Rp Discovery messages are not reached
because the incoming interface and the outgoing interface are the same, then
you should think about using a Tunnel between these devices.
You can test your lab using the no ip mroute and deb ip mpa to see if there
is an oil to null or an RPF Failure for any group.
And from the PIM NBMA MODE Part: I've heard hear that extra configuration
does not makes a question wrong .-

Asunto: sparse-dense mode
Hi Group,
I have 3 routers connected in a triagle, Router A, B and C.Router A is hub
usinfg sub int . .I have to enable RP on router B for 1 group, another RP on
router B for different group.Router A is RP-discovery.We need to enable PIM
spares-Dense mode only on all 3 serial int running FR ( enable spare mode on
all int, and let Dense mode to discover all groups if RP fails)
.If i enable PIM nbma mode on all 3 serial interface,I get warning that nmba
mode is not recommended in this mode but interface still accept the command.
Will we loose the point in the lab if we still force PIM NBMA MODE on
sparse-dense mode, enabled interfaces ?.
Regards.
