@mjk Pretty sure there is an Enterprise Cloud setup out there that is matching all of it at once ​:anko_giggle:​

@mjk #l2tp is also probably in the stack somewhere.

@mjk It misses the old gods IPX and SPX.

@mjk For those unfamiliar, there are myriad networking protocols that operate over Ethernet that are not IP.

That includes DECnet of course, and MOP traffic including periodic MOP SYSIDs, and DEC thoughtfully reserved Ethernet type 0x6006 for their customers, so who knows what that type contains.

Random Ethernet type thought: does VSI or HPE “own” 0x6006 now?
