[Xorp-users] No more than 25 OSPFv3 neighbors fully adjacent?

Thanks a lot for the guidance. I will do it ASAP. Indeed the OSPFv3
process seems to "partially" exit 
and no longer functioning. What puzzled me was somehow "ps -ef" show
xorp_ospfv3 still exists...

Hi,

The OSPF process seems to have exited, typically the XORP processes
will
print a message before exiting, it would be useful to see this message.

Could you run the router manager in the background and capture the
output, the following works for me with /bin/sh:
# ./xorp_rtrmgr -b ./ipv6ospf.boot > log 2>&1 &

If you are not already could you also try building from CVS so that you
have all of the fixes.
