I would start with some BGP debugs and some tcp access lists as an audit
trail. Your two routers do not care that they are connected to the MPLS
L2 VPN and should be unaware of it completely. If the TCP keepalives
arent getting across the l2tunnel, then it is possible you have some
changing ldp/tdp topology causing you to drop labels.

Hi,all
