I have great hopes for Schprokits. The idea behind it is outstanding - an Ansible for networking. It must be tough though, integrating all major vendor APIs seamlessly into a product. I have faith in Jeremy and his team...hopefully they are close to shipping code =) *Pablo Lucena* On Fri, Mar 13

DMVPN is very flexible, and is designed for this type of scenario. Cisco definitely supports it. Not sure about Juniper, but its essentially mGRE + NHRP. You can use IPSec to encrypt the tunnels, and if you require spoke-to-spoke connectivity, there are some optimizations in Phase-3 DMVPN that make
