[j-nsp] PFE-forwarded IPv6

Can you post the relevant configuration from the box? I expect that the host is directly connect to the MX-960; and the interface that is facing the host is running RA; furthermore if you look at the routing table on the host, you will see a default route to the MX's link-local address?

Now is the 6in4 tunnel configured on the MX or is this further upstream? Does the other end of the 6in4 tunnel know how to reach your prefixes?

Kind regards,
Truman
