I was looking for some information on bonding interfaces in Linux and ran into this fantastic post by @packetsar that both summarizes the options, and introduces us to an interesting troubleshooting scenario with LLDP.
Fantastic work!

Want to determine the maturity/stability of a networking product? Find out how much of its feature-set has #IPv6 parity with legacy IP.
If it has limited IPv6 support, then it likely has major bugs you will encounter, even if you aren't using IPv6 at all.

I don't understand how people hate on VTP and still embrace dynamic routing and automation in general. Especially since VTPv3 fixes the old issues cited when hating on it.
VTP or no VTP? And why if no VTP?
