All of our Calix gear is on ERPS.

We used ERPS with great results. Sub millisecond caliber with no precepts
packet loss even for voice. But, you can't see anything past the shut down
ports. We used it with planet switches. We had to manually shut down ports to
test the alternate paths which in most cases didn't happen often enough.
We did have a failure because we didn't test the alternate path often enough.
If there was a way to automated that it would be better.
I would listen to Hinojosa this. He has been where you are going.

"You also loose a great deal of bandwidth If one side is blocking an fully
modulated link and the active path is no running full rate."
Strong reason not to use a ring in general. In this case, I have two 10G
legs. One is only 550 meters. If is is gone, then something is really wrong
and the other will be out as well since it is much longer. Good argument for
running G.8032v2 so I can put the owner on one side of the long link with the
neighbor on the other. This way the unused link will be the long link.
Thinking about it, another reason to do G8032v2 is at least with Calix, all
the links with ERPS need to be the same speed, ie 10g, but with G.8032v2, at
least according to the docs, You can run different interface speeds on
different legs so I could leave an older 1G Siklu on the backup path for now.
We would obviously run the Siklus out of band. I have existing management
networks at each of these locations, but you could just connect the management
interface on the radio to another port on the E7 and run a management VLAN on
the ring.
We are currently running Juniper MPLS on routers (MX and M7i). Could look at
replacing the M7i routers with Juniper switches but they don't do well outside
of a data center environment IMHO. That is the path I was going down but doing
it on the E7s is much easier from a cost, power, and cooling perspective. The
E7-2 on the other hand, is designed to run in a cabinet by the side of the road
and half of them are already in place.

I am not too familiar with the Calix G8032 but some of the things I could
see being issues would be pulling management out of the ring so that you don't
loose connectivity to the radios on the blocked port. You also loose a great
deal of bandwidth If one side is blocking an fully modulated link and the
active path is no running full rate. If it uses CFM/OAM for link monitoring you
could have issues configuring this over the radio links. You pretty much are
forced to do this or run out of band management and force the ports down on
link failure.
Personally I would look in to Juniper Nokia 7210 or ciena 3928. The Nokia
does full MPLS ciena does MPLS-TP and would possibly be abetter solution.

After moving most of our network over to VPLS, I'm working on pushing 10G
further into the network. It doesn't make a lot of sense to do this with
routers (cost & power) and since we use a lot of Calix gear for our GPON and
already have some of it in place it makes sense to me to just set up a 10G ring
and hang routers off of that where we need them. A couple of the legs are
going to be wireless 10G links for now so I'm looking for feedback on G.8032v2
vs ERPS rings with wireless paths.
Going to be running ~20-30 Service VLANs with multiple CVLANS and 20-30
other single tagged VLANs over the ring (router to router, dedicated links,
etc). The only drawback I see is the inability to do traffic engineering the
way we an with MPLS VPLS but I'll still have that with the transport to the
core ring.
Any gotchas I should look for? Issues with wireless? benefits of one vs
the other?
