Abstract
Embodiments of the present invention include systems and methods for preventing traffic loss of data directed to a destination in a network. A router in the network attempts to install a route prefix of a destination or an ARP entry in the router. If the attempt fails, the router determines whether the routing device originates the uninstalled route prefix or a set of route prefixes pointing the uninstalled ARP entry as next hop in an internet protocol (IP) reachability. If the determination is negative, the router sends a message to a neighboring router to add the router to the exclude route list of the neighboring router. When the neighboring router determines an optimal route involving the uninstalled route prefix or the set of route prefixes pointing the uninstalled ARP entry, it looks up the exclude route list so that the router is not included when determining the optimal route.
