route traffic between different VPN networks

[usmanimuhammads]

Dear Members

I have arequirement in which i have to route traffic  between two VPN networks.First VPN is setup between Site A and Site B while another VPN is created between Site B and Site C. Now site A LAN has to access site C LAN while site C LAN has to access site A LAN but I am not able to configurev this.

  Due to some reasons VPN between Site A and Site C directly is not allowed. Both VPN's have been configured suuceesfully and working. Kindly help in creating the scenario. Two VPN's created between site A to Site B and Site B to site C are site to site GRE tunnels.

Thanks & Regards

How do you want to have the VPN tunnels: two tunnels  (A-B-C) or three tunnels (A-B + A-C + B-C)

We will be using two tunnels please see attached diagram.As per diagram 10.11.12.1 must be able to access 20.20.20.2 and 20.20.20.2 must be able to access 10.11.12.1.
