Imal,
Autorp Listener permits the groups 224.0.1.40 and 224.0.1.39 to be distributed
in dense mode, even if you have "sparse-mode" configured on the interfaces.
BSR does not require this command. BSR routers announce themselves using the
PIM neighborship on link-local multicast address 224.0.0.13. BSR
RP-candidates unicast to the BSR. So BSR does not need to create any
multicast distribution trees in order to inform routers of RPs.
HTH,

Hi Group,
I need to clarify the following..
if we are only allowed to use sparse-mode, we need to use 'ip pim auto rp
listner"
in case we use auto rp for rp election..{Pls correct me if I am wrong}
Do we have to use the same command, if we have to use BSR instead of
Auto-rp?
Cheers,
Imal
