Currently I have a network that is set-up with a simple star topology. 2 7500 routers that connect through about 90 T1 lines with cameras at the ends. On the end of one T1 line I have a router, an encoder, and a analog camera. The encoder supports multicast. How to do I configue my 2 central routers and each end router to support multicast?
In addtion do I assign each encoder with a specific multicast address with each one being different?
ie: 126.96.36.199/30 or do use the whole subnet 188.8.131.52/24
Any help with this would be great.
