"Frame Relay devices connect with each other through virtual circuits. Each virtual circuit is uniquely identified by a Data Link Connection Identifier (DLCI). In environments in which permanent virtual circuits (PVCs) are used, information regarding added or deleted PVCs and information about availability or unavailability of PVCs is carried through a Local Management Interface (LMI) with the use of status bits.
The Frame Relay switch within the local PVC segment deduces the status of the remote PVC segment through a Network-to-Network interface (NNI) and reports the status to the local router. If local management support within the switch is not end-to-end, the keepalive feature is the only source of information about the remote router. Frame Relay end-to-end keepalives provide status to verify that end-to-end communications are working and that traffic is getting through."

Introduction The purpose of this document is to demonstrate the Open
Shortest Path First (OSPF) behavior when the V-bit (Virtual-link bit) is
present in a non-backbone area. The V-bit is signaled in Type-1 LSA only
if the router is the endpoint of one or ...
