G.8032 Ring ID Question

Hello everyone

I am working on turning up a G.8032 ring with a mixture of Cisco ASR9K and ASR920 routers in addition to a few Calix E7 shelves. 

The Calix gear confirms strictly to the standard and expects/sends R-APS messages to the multicast address of 01-19-A7-00-00-[Ring ID]

It looks like the ASR9K and ASR920's are sending the frames to the G.8032 ver 1 standard address of 01-19-A7-00-00-01

This, of course, prevents the ring from working properly. 

A few questions:

Is there any way to manipulate the R-APS destination MAC so it confirms to the standard?

I noticed under a Cisco G.8032 config, you must specify the APS Message Level. Is this the Ring ID as it pertains to the G.8032 standard?

I looked through the G.8032 standards document and cannot find a reference to an APS Message Level so not real sure if changing that value will accomplish my goal or not. 

Thanks for the feedback.

Hello,  We are going to use a few NCS540s to build a 100 gig ring and drop off lags to our Calix Gear.   Did you ever get your 8032 issue resolved?
