[Olsr-dev] I had a persistent loop in laboratory network
Wed Oct 20 10:19:49 CEST 2010
it looks as if both .179.155.133 and .179.196.113 think the other one is
closer to .195.228.128 (is this a hostroute or a network?)
check with txtinfo, if they have wrong/different topology
if yes: find out why the have wrong topology
if no: find out why they have wrong routes with correct topology
but hmm you already restartet your malfunctioning olsr nodes, so you will
have to wait for the next loop,..
or do you have more data than just this one dot-draw output?
