the challenge is that when you tout your vm mobility play as “zero touch” after move (i.e. you don’t have to re-ip your vm/application/etc to ensure 100% business continuity) — you need to have stretched layer-2 between locations to ensure proper functionality. things like bgp host-route

The only reason for this is because some vendors do not want learn tcp/ip just so they can force their own customer support on others. So they don't want to deal with it and sell you on layer 2. Mario On Feb 1, 2018 2:02 PM, "Aaron Gould" wrote: > As my teenage son would

So I think (I could be wrong as I'm not a server guy) that all this L2 network emulation is because of server virtualization and moving vm's or vmotion or something like that, and that they need to be in same ip subnet (aka bcast domain) correct ? *if* that's true, and *if* all this layer 2

This has been standard n7k operations since the platform supported contexts. Much like ASA — interfaces need to be dedicated to a context from the management-plane perspective. OTV requires a separate context due to inability to have SVI and OTV in same context. OTV essentially becomes a part
