I will check that out, but I think that as long as both ends are the
same (both with rewrite, or both without) it will work correctly.
I did solve this problem, though I'm not sure exactly what the true
nature of the issue really is. As you noted, everything looks right, but
I can't get any actual traffic across the VC. Upgrading to 16.7.1,
without any other changes, makes it work.

Can I omit the "rewrite ..." on both sides?
Why would you want to? I think that if you do that, a VLAN tagged
frame coming into one end with VLAN 95, will be send over the
pseudoiwre with the VLAN tag still present, at the other end it will
have VLAN 95 push on egress, so it will leave the other end double
tagged with an inner and outer VLAN tag of 95.
Here's the status on both sides:

^ everything looks fine here. Is this still not working? If not, did
you have it configured with the "rewrite" statement?
Cheers,
James.
