Backup with VPN LAN-TO-LAN?

hdoramane · ‎04-04-2008

Hi,

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?

THANKS FOR HELP

REGARDS,

Hi Hassan,

As I know, a VPN connection can not act like/be/backup a trunk link. You can open up a question as "Backup trunk link over S2S VPN" in "Network Infrastructure" in "WAN Routing & Switching" section to make sure.

A workaround would be configuring Dynamic routing protocols with high costs, but that would not work if you have same VLANs at both sites.
