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

[Buchanan, James]

The MPLS provider does not support multicast routing across the WAN.

I have worked around this in the past by using a GRE tunnel. Basically, you create a multicast route (ip mroute) to route the multicast traffic through the GRE tunnel, which is essentially a simulated layer 2 connection through the MPLS network.

It is possible Singlewire has a relay of some sort for this situation as well that would allow you to avoid a GRE tunnel.

Greetings,

We're changing out some point to point circuits with MPLS circuits.  The audio on a page via Informacast no longer makes it through.  The phones beep, so the connection is made, but audio is silent.  The point to point circuits are working just fine.

Long shot, I know, but any ideas out there?

Thanks
jeff
