Trying to see how this might be possible (or how it "should" be done) on a Ciena platform. We have MEF services (simple E-Line) that we offer clients. We also carry a management VLAN to manage our CPE (not Ciena) over a different VC. We now have a partner that we have an NNI with, and we pass along the S-Tag to them, but how do we get the mgmt VLAN down to them too? The problem seems to be that our CPE that we need the mgmt. VLAN on is CPE of ours AFTER their CPE. Just looking for some direction or others who have certain best practices they are willing with share! Thanks in advance.
