[cisco-voip] Any Informacast Users? with MPLS?

[mthompson729 at gmail.com]

James,
Not necessarily. IP in GRE is a very good solution, but there are carriers  
that will support Multicast over MPLS. We just turned up Informacast /  
Relicast for a customer within the last few months. The carrier is AT&T and  
they definitely support it. There are a number of questions to answer, is  
it Sparse or Dense, what your ip / port ranges will be, etc. Once we  
completed that form, about 3 weeks later we were cleared to do our  
configuration.

I was anticipating a ton of troubleshooting, but didn't run into any issues.

That being said, this was the first and only Multicast over MPLS  
implementation that I've done.
