I have 2 sites interconnected via Fiber ( 1km) which trunk 4 vlans, the both site are on the same subnet.
the fiber is connected on catalyst 3550 on the central site and the catalyst 2960 on the branch site.
i need to configure VPN IPSEC lan-To-LAN using ADSL connection between 2 sites to backup my fiber connection when its down.
please advice if you have a solution to backup my fiber connection with VPN TUNNEL?
