I have a 3 network setup for MIP6 (aka Kame snap of a few weeks ago). consider one section of the network. CN (host) <-> fec0:200:: <-> HN (router) <-> fec0:10:: <-> MN (host) the fec0:10:: network is an 802.11b network. I can either set it up as an AP based connection e.g. HN - wi0 - - - - AP - - - - an0 - MN or as an adhoc connection HN - wi0 - - - - - - an0 - MN for some reason, every now and again, the connectivity between the two ends drops off, with either a No route to host or ping rejection, depending which side of the remote host I am pinging... this is independant of adhoc or AP sometimes I can get the network connected by doing wicontrol -c 1 or some such - starting tcpdump on the an0 interface after starting the pings seems guarenteed to kill connectivity. but starting tcpdump ahead of time mostly doesn't. the hosts are accepting rtadv and the routers are forwarding ipv6 traffic. the same behaviour if I set up IPv4...
