Hi,
I just catched, that N7k is EoL announced. What a shade. I am using good old OTV to interconnect 3 DC sites, it is running, no outage for years... The OTV technology is simple to configure, it works, is stable so why to change it??
I know, that N9k is doing the similar job with BGP EVPN or with ACI, but I am not the fan of APIC = big central world brain machine. I like the simple things.
