This document proposes a lightweight mechanism that the LDP protocol may use to help minimize the impact introduced by transient interruptions to an LDP session's TCP connection, with a focus on connection preservation for signaled Layer 2 circuits. A new LDP Cork message request/response mechanism is specified. New message types are defined for the delivery of graceful restart events. Finally, procedures for utilizing this mechanism are detailed.
