   When route servers are used, the data plane is not congruent with the
   control plane.  Therefore, the peers on the Internet exchange can
   lose data connectivity without the control plane being aware of it,
   and packets are dropped on the floor.  This document proposes the use
   of BFD between the two peering routers to detect a data plane
   failure, and then uses a newly defined BGP SAFI to signal the state
   of the data link to the route server(s).
