[j-nsp] Interconnecting spines in spine & leaf networks [ was Re: Opinions on fusion provider edge ]

[Aaron1]

Well, I’m a data center rookie, so I appreciate your patience

I do understand that layer 2 emulation is needed between data centers, if I do it with traditional mechanisms like VPLS or l2circuit martini, I’m just afraid if I make too many connections between spine and leaves that I might create a loop

However, I’m beginning to think that EVPN may take care of all that stuff, again, still learning some of the stuff that data centers due
