For clarity, we should define VN in some draft (framework?), state that VN and CUG are the same, but stick to using one term, preferably VN. Note that Wikipedia defines CUG as follows: Closed User Groups are groups of GSM mobile telephone subscribers who can only make calls and receive calls from members within the group. Any other calls would be rejected. The definition is pretty close, but it goes to show that CUG comes with overtones that may confuse people. One refinement might be to define L2 and L3 VNs off the base definition of VN. > Yakov Rekhter <[email protected]> writes: > >> There is a definition of L2-based CUG in >> draft-rekhter-nvo3-vm-mobility-issues Thomas, the reference I gave below about where L2-CUG is defined is wrong -- not the EVPN draft, but the one above. <rest snipped> Kireeti
