But can you clarify who is dropping who (i.e. which end is timing out)? The message on LEGATO says "dropped by adjacent node" not "dropping adjacent node", which makes it sound as if MIM is timing out, not LEGATO (and then somehow telling LEGATO that, which is another mystery). Or is this just a poorly worded message? No, the message is very precise. If you see a message on LEGATO which reports adjacency MIM down for that reason, it means LEGATO received an Ethernet router hello message from MIM that no longer lists LEGATO as one of the routers that MIM can see. MIM will have a reason for not reporting LEGATO any longer. It should have logged a message stating that reason. paul
