It's a Juniper so probably the upstream router.

Hello Martin,
the Infos you wanted:
176.9.157.65 78:fe:3d:46:ed:9d re0 4m54s
Which computer is that? IPv4 doesn't help. We're dealing with IPv6.
This MAC address is the one that ends up in your fe80::%re0 route on 6.0
and doesn't in current. The question is *why*?

net.inet6.icmp6.nd6_debug: 0 -> 1
Please use 8 or higher, put that in your sysctl.conf and look at which
error message you get in /var/log/messages
