Abstract
In one embodiment, a router generates a notification message that indicates the router is to be gracefully removed from service. The router sends the notification message to peers of the router in a network. The router then continues to forward packets for a grace period after sending the notification message, to permit backup paths to be propagated to peers, and to be put into service, prior to withdrawal from service of paths through the router. Thereafter, the router is removed from service at the expiration of the grace period.
