Dynamic Routing Through IPSec Without GRE – Using VTI’s

Dynamic Routing Through IPSec Without GRE – Using VTI’s

On a previous post, we created a GRE tunnel to permit routing protocol through an insecure (Internet) network and protected it with IPSec. As you all should know GRE adds another layer of encapsulation (at least 4 bytes), which means more overhead. One major advantage compared with the traditional method of IPSec is that, since … Continue reading Dynamic Routing Through IPSec Without GRE – Using VTI’s

DMVPN – Dynamic Multipoint Virtual Private Network (Part-3)

Continuing the previous configuration left from Part 1 and Part 2 we will finally enter the dynamic creation of tunnels between the SPOKES. To achieve this we will need to change the configuration in the tunnel interfaces of both the HUB and the SPOKES. Starting a clean sheet with the same initial configuration as before. … Continue reading DMVPN – Dynamic Multipoint Virtual Private Network (Part-3)
