Abstract
A method and apparatus for processing link down events associated with links between adjacent nodes is described. A node receives link down events associated with a link fault protocol for a link between the node and a neighboring node. In response to receiving the link down event, the node removes a data structure associated with the neighboring node from a forwarding table associated with a routing protocol running on the node. The node reserves the data structure for speedy adjacency recovery. In addition, the node places the neighboring node in the initialize state of the routing protocol.
