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.
