Thanks. We'll let you know when a new response is added.

Router 1 sees router 2

Router 3 sees that router 2 can be reached through router 1
Router 4 sees that router 2 can be reached through router 1
Router 2 goes down.

Router 4 cannot get through to router 2
Router 4 asks for a new path to router 2
Router 3 replies that the route is through router 1
Router 4 sends a packet to router 2 through router 1
Router 1, in the meantime, asks for a route to router 2
Router 1 gets the expected replies from routers 3 and 4 – go through router 1
– now, why should router 1 believe routers 3 and 4 when router 2 is down?
