Lee,
I thought you have to use tunnel as well as static mroute. Do you have any sample configs.
=============================================
eg:
on RC:
int tu 0
ip unnumbered s 0
tu source s 0
tu destination 133.13.13.1
ip pim sparse-dense-mode
ip mroute 225.25.25.25 255.255.255.255 tu 0
==================================
thanks
Mani

Mani,
Ip pim nbma-mode only functions with sparse, although you can configure it
with sparse-dense.
Both spokes have a direct connection with the mapping agent, so I suppose
you have a split horizon problem in force. You could either use static
mroutes or a tunnel.

Lee.

Mani,
You can announce any multicast enabled interface as the RP,
although I would normally enable it on a centrally located router it
does not have to be. I will assume you are using sparse-dense mode
since you are using auto-RP. The hub router will not send packets out
of ports it received the traffic on so you could do a static mroute
since your configuration is all on the same subnet and will not allow
for separate P2P sub interfaces. My question would be do you need the
ip pim nbma-mode with running in sparse-dense mode. I know you need it
with sparse mode to track individual join and leaves, but not sure if
you need it if you are running sparse dense.
Regards,
George

Subject: multicast doubt of frame-relay hub and spoke
Guys please look at the scenario below any help is appreciated.
Frame relay hub and spoke: RB hub and RA/RC spokes
e0(RA)s0--------------------s0(RB)HUB-----------s0(RC)e0 spoke
s0 =133.13.13.1 s0 133.13.13.2 s0=133.13.13.3
e0 =133.13.10.1 e0 133.13.20.1 e0=133.13.30.1
lo0 =133.13.1.1 lo0 133.13.2.2 lo0=133.13.3.3
scenario:
make RB mapping agent
make RA e0 Join mcast group 225.25.25.25 make RA announce it as RP.for
multicast group 225.25.25.25
questions:
-If not asked to enable mcast on lo 0, is it ok to put lo 0 in pim and
announce RA lo 0(ip pim send-rp-announce lo 0) or should we announce e0
-once this is configured, unable to ping the mcast 225.25.25.25 group
from FR other spoke router(RC), so how we solve, even if a question
doesnt asks for static mcast routes and introduction of tunnel
interfaces, can we use it, how
thanks
Mani
