Hi Lothar, 2017-09-30 19:42 GMT+08:00, Reith, Lothar <[email protected]>: > Hi Gang, > > Let me rephrase your question as follows: Is it possible that a L3 VNI > instance uses the same identifier as a L2 VNI instance,
Yes. That is my question. > and if yes Most important thing to me is to validate the statement. I noticed that there is a clear restraint that L3 VNI should be different with L2 VNI in the current implementation. If the statement is valid, those restraints should be removed. I guess it will give additional benefits to the operations. > would it be a recommended practice or not (why not?). Sure.
