   This document specifies use of the BFD (Bidirectional Forwarding
   Detection) protocol in RBridge campuses based on the Rbridge Channel
   extension to the TRILL (TRansparent Interconnection of Lots of Links)
   protocol.

   BFD is a widely deployed (Operations, Administration and Maintenance)
   OAM mechanism in IP and MPLS networks.  However, in the present form
   a BFD packet cannot be sent over a TRILL network as it is either IP/
   UDP encapsulated or encapsulated directly over Multi Protocol Label
   Switching (MPLS) or using Associated Channel Header (ACH)
   encapsulation.  This document defines BFD encapsulation over TRILL to
   address this shortcoming.
