Using the configuration of the previous post we will configure R1 external interface as a Dynamic Virtual Tunnel Interface that will allow the dynamic creation of Virtual-Accesses one per connection. We will also add a new Router R3 to the mix as another peer in the flexVPN topology to get a hub and spoke topology. … Continue reading FlexVPN – DVTI – Dymanic Virtual Tunnel Interface
