A method for reducing fault detection time in a network includes routers configured to exchange messages via at least one switch to check mutual reachability, each message including a list of routers reachable from the sending router. The method includes snooping, by the switch, a message from a router to extract the list of routers reachable from the router; and, when a network fault occurs that prevents the router from being reachable via the switch, sending, by the switch and to all the other routers connected to the switch, a network fault message including an empty list of routers, so that the receiving routers, not seeing their own identifier in the list, declare the adjacency with the sending router closed, and proceed to reroute traffic on a new route. |
