RE: Multicast Traffic on Backbones
- From: Michael Whisenant

Most multicast backbone providers have links that show that they mBGP
with peers and offer MSDP as well. This allows for the customer on one
providers network to access a source on another providers network. Of course
there are issues with the 5 bit overlap in multicast address space, but it does
work. There are commercial companies that have registered/reserved particular
addresses for their applications as well. While I think that today the amount
of multicast traffic is low, it will continue to increase.
