I recently spend a few days debugging what in the end was user error on my part.

Here are my notes in hope they help someone else.

First, 'ip -6 route show vrf vrfX' will not show some of the
routes (like local routes) that will show up with
'ip -6 route show table X', where X == vrfX's table-id

If you run 'ip -6 route flush table X', then you will loose all of the auto
generated routes, including anycast, ff00::/8, and local routes.

ff00::/8 is needed for neigh discovery to work (probably among other things)

local route is needed or packets won't actually be accepted up the stack
(I think that is the symptom at least)

Not sure exactly what anycast does, but I'm guessing it is required for
something useful.

You must manually re-add those to the table unless you for certain know that
you do not need them for whatever reason.

Thanks,
Ben
