Hi,
I need help in understanding IP multicasting specially sparse mode.... bit
confused
In sparse mode (Auto RP Scenario) we have a RP and Maping Agent (MA) . RP
announces its self to MA and MA receives the request from clients to join a
specific multicast group for which RP is configured or MA announcing. Source
send the source active message to the RP for multicast group it has. Now my
question is that whats the function of PIM DR how it works. I just know that
PIM DR is elected on the bases of higher priority or the higher IP Address.
how PIM DR works in relation with RP or MA
If I am not wrong Source sends unicast packets to PIM DR for specific group
then DR sends those packets to RP and then RP register itself with DR. if its
right then its mean Source dosent communicate with RP ??
Please someone help
Thanks
