Description
Set the length of time that a node considers a neighbor reachable until another reachability confirmation is received from that neighbor.
After receiving a reachability confirmation from a neighbor, a node considers that neighbor reachable for a certain amount of time without receiving another confirmation. This mechanism is used for neighbor unreachability detection, a mechanism for finding link failures to a target node.
Options
