- might be just a problem of connexion time.
- I would try traceroute -w with some higher number than the default and see if it is still the same issue.
might be not the problem.

Hello,
First, sorry for cross-post but the problem is related to a lot of mailing-lists.
I have a strange problem on one of my router: lacr1.us.ndsoftwarenet.net.
I get "connect: Network is unreachable", when i try a traceroute or a connection from the router to a host on 6bone. The problem is random, because a destination www.kame.net can work but not www.6bone.net (for exemple) and after restart zebra www.6bone.net can work but not www.kame.net. Often, all destinations don't work.
OS: Debian 3.0 (sid/unstable) with last update Kernel: 2.4.18 (i have try kernel 2.4.18 USAGI (last snapshot) and standard (from kernel.org) but same problem Zebra: 0.93 CVS (i have try 0.92a too but same problem)
It's not the zebra configuration (zebra.conf, bgpd.conf), because all my routers have the same configuration.
How i can fix this problem ?
Any help are welcome.

When a user, connected on router try traceroute:
wireless:/etc/zebra# /usr/sbin/traceroute6 phenix.rootshell.be traceroute to phenix.rootshell.be (3ffe:8100:200:1fff::25) from 3ffe:81f1:3:2006::2, 30 hops max, 16 byte packets 1 tun6-0-lacr1.us.ndsoftwarenet.net (3ffe:81f1:3:2006::1) 118.109 ms !H 125.594 ms !H 119.42 ms !H wireless:/etc/zebra#

When i try a traceroute from router:
# traceroute6 www.6bone.net connect: Network is unreachable

Kernel routing table, good route on the good interface:
