Re: [B.A.T.M.A.N.] Suggestion for routing improvement on poor links

The routing protocol is known to have problems when a node suddenly disappears. A received OGM is what triggers updates to the metric. If you stop receiving OGMs the metric is no longer updated until the node is purged as dead. This for example causes problems with nomadic/mobile nodes. They can go around a corner, loss line of sight, but still be considered the best route until purged as dead.

But if you keep receiving OGMs via another neighbour you will have a route switch *before* the old nexthop is considered as dead.
