Mpls lab help

adriansizemore

anyone have any idea why my ce links to each other's LBs would bounce for 30secs and restore?

I checked my MPLS cloud and OSPF has been stable for over 24hrs. My eBGP connections to the vrfs on the PEs have remained up and stable. I cannot figure out why my BGP sessions are going down. Here are the details of the alarm and ce configs:
