my topology is like this:
Source - R1 - R2 - R3 - Host
R1 has support for SSM and PIM-SM
R2 has support for SSM and PIM-SM
R3 has support for PIM-SM and IGMPv2 only
Host today uses IGMPv2, but IGMPv3 is coming soon
My focus is to have, as last step, a SSM-IGMPv3 infrastructure. But today I couldn't.
How to create a solution that could be simple to migrate from PIM-SM to SSM?
First of all, I think, I've to assign a 232.x.x.x range for multicast groups, is it? Then I've to implement a PIM-SM solution, whit RP, ... or maybe I could use SSM on R1-R2, and SM on R3?
Any advice will be appreciated
