I have a couple of clients who have proposed a design where you put all internal and Internet VLANs in a single bond. One client has dual 10G interfaces which they want to bond and another wants to bond eth1 through eth8. The end result is the same. All VLANs, including Internet in the same logical interface.
I have my own concerns about this approach (resource allocation, availability and security etc) but wanted to hear what the combined knowledge of this community thinks about it. I'm no design architect and these designs were proposed by architects so I need more confidence before I oppose this design. If my concerns are at all valid of course.
