Hello,
All my cisco core switches multicast interfaces are enabled with PIM version 2.
My understanding of the RP reachable message is that it is relayed down the shared tree to other PIM routers so they know the RP is still up.
If they don't receive that message then they assume they need to find a new RP (if they can).
What is the purpose of "RP-Reachable" and why is this packet PIMv1 format rather than PIMv2? format should have been with PIMv2 ..no?
I have attached the details. could you please check & help me to understand this.
Thanks & Regards,
Shibu
