Re: multicasting issue - strange

Hi All,

I have done one more test :-

Topology :-
                    R4(reciever)
                          |
R3 ------------ R5(MA) -------R2-------R1(RP)
(Source)

Now all the interfaces in all the routers are configured in spare-mode
only.listner command is not configured.

And I am seeing RP mapping on all the routers except RP (R1) it self. Also
able to ping from R3 ro R4.

Regards,
Shekhar
