Abstract:
LDP label switching may be discontinued gracefully on one or more selected ones of multiple links interconnecting a pair of label switched routers (LSRs) while leaving label switching in operation on the remaining LDP-enabled links. Mechanisms for graceful shutdown of LDP on a selected link are added by way of modification to one or more of: e.g., LDP discovery Hello messages, LDP Label Withdraw/Label Release messages, LDP Notification messages.
