We are trialling a video conferencing deployment. Our WAN topology is via BGP connections to a carrier's MPLS cloud.
We have configured a Communications Manager 6 server. When we connect our 2 test routers via a local test router using EIGRP, we initiate a call and are able to see a single RSVP reservation establish and hold up indefinitely. When we attempt a second video call, it is correctly refused as per our intended policy. However, when we connect the 2 test routers to the carrier's IP cloud via BGP, we cannot get the RSVP reservation to hold up, it drops after 60 seconds (as per the CM6 setting) and we note Path Tear messages in our RSVP debug.
Could anyone provide advice on why this would be happening. Configs attached.
