Hi, We deployed SRv6 as part of our new mobile network in Italy (Iliad Italy). SRv6 with SRH is carrying commercial traffic of millions of subscribers for several months, with line-rate performance and on several platforms and operating systems. We also started to extend our deployment to our national network in France (Free & Free Mobile), we already have significant inter-AS SRv6 traffic.
