In reply to Steven Wood.

@StevenWood - thank-you. So Cisco views Viptela as Cisco's premium/preferred SD-WAN solution going forward? I understand that iWAN/PfRv3 support and even development will not go away, but just wondering whether Viptela is viewed as a complementary solution that sits alongside iWAN going forward, or if Viptela is viewed as the evolution and long term replacement for PfRv3.

Also, will Viptela make use of the 4k service container resources? If yes, will a Cisco SSD be required to run Viptela in this service-container space, or will Viptela software run on the routers as they ship, given the appropriate licensing?

Thanks!
