Hey Sabri, Eventually they have implemented everything ;-) Arista was a really special case, routing stack they acquired (NextHop) had no mpls (quite some time ago), 90% of their revenue was coming from IP only networks.
Life is good, MS is treating me well :). Kids are growing, Marina’ business doing ok. How’s life on your side? Would love to meet, lunch or so?
