This also happens whenever I change the MTU on eth0 - it will alter the MTU on routes *I* have added too. While this is valid behaviour for a new MTU that is too low for the route it is not for an MTU above the route. Changing the MTU also allows the "next RA with MTU set changes non-kernel routes too" problem to occur again. -- Simon Arlott - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
