I would expect the Routers not to fallback to dense mode.
Ip pim auto-rp listener temporarily allow flooding via the 224.0.1.39
and 224.0.1.40 group (someone should correct me if I'm wrong). That is,
it enables the routers to use dense mode (flood) only for those 2 groups
no ip pim dm-fallback ensures your Routers don't flood for every other
group other than the 2 groups (224.0.1.39 and 224.0.140)
So even with no ip pim dm-fallback, your mapping agent still need to
push out the RP information using the 224.0.1.XX group towards the other
pim routers. Or in other words, if you have sparse mode configured and
no ip pim dm-fallback, the routers can still obtain RP information from
the MA, provided you have the ip pim auto-rp listener configured.
Many Thanks

Hi
In multicast, if I have the below configuration
ip pim auto-rp listener (On every Router)
no ip pim dm-fallback (On every Router)
ip pim send-rp-announce loopback0 scope 16
ip pim send-rp-discovery loopback0 scope 16
int lo0
ip pim sparse-dense-mode
In the above configuration all the routers will work in sparse mode
or dense mode?
Does the command " ip pim sparse-dense-mode" takes precedence over
the command " ip pim auto-rp-listener" ?
Thanks
Amit
