RFC 4610 describes how anycast-RP works using PIM, without MSDP.

How can you have anycast without MSDP? What will keep all of the RP's synchronised.

Hi Bandar,

 

            You must be looking for anycast RP. There are many ways how one group can have

multiple RP's like

1.       anycast rp with msdp

2.       anycast rp without msdp

3.       scoped multicast addressing

 

There is no way for Rp to know any details about DR's.

Hi,

It is me again. I am a P.h.D candidate at SMU and working with Dr. Suku Nair on IPTV project using PIM-SM.
We are exploring the possibility of having multiple RPs for a single group. As you know the RP has no knowledge about the exact structure of the tree.
We need for the RP to know the tree structure to calculate the tree cost.

Here is where my question comes, Is it possible for the RP to know the path and cost to all DR's and then use that to find its tree cost? and if so, is this path picked different for Unicast or Multicast since we know that PIM uses RPF to set up the path to the RP?

Its all related to the MRIB and how it chooses the path and I really did not find any information for that.

Thank you kindly for your assistance.
