Hi Zhang Li, Perhaps I’m not understanding the problem that you’re trying to solve. It seems to me that what you’re suggesting is that we create a special encoding to handle the case where someone has multiple VLANs over one link between two routers. Is that correct? Why would anyone want to do that? I dislike adding hair to the protocol over a situation that should not exist.
