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

[Ian J. Pitts]

Jeff,
The problem you have is related to multicast. Normally MPLS does not natively support multicast traffic. You will need to setup GRE tunnels to encapsulate the traffic over the MPLS network. This essentially turns your new MPLS network back into a hub and spoke network as it relates to multicast.

Cisco document that explains the configuration can be found here.

You can also look at other solutions in the market that do not require multicast over the MPLS network.  Since the puck mailing list is not a sales tool I will refrain from mentioning our notification product.

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
