yes, an IPv4 BFD down event will tear down the whole adjacency. Note that when running MT, you'll also have to enable IS-IS IPv4 topology on the interface the same time, otherwise IS-IS won't register as a client to BFD. --Daniel. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
