I know that the RP at it current state does
not know any details about DR’s. My question is, is it possible to modify
PIM-SM and make it learn.
Our research is about relocating the RP
depending on the shared tree cost, so it is very important for us to know the total
cost of tree (link cost metric, or delay metric).
With my best regards.

multiple RP's
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.

Subject: [pim] MRIB and multiple
RP'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.
