Using Primary & backup Internet Connection Real Time
Hi!
I have two internet connections, primary Radio Link while secondary Satellite connection. Both of the links from the same ISP and have same Real IP. Whenever the primary link goes down one have to manually turn on the backup connection and sometimes this downtime really impact the online application we are running.
Now the scenario is like this Internet connection is terminating from there Indoor unit / Modem into my Cisco 800 series router. There is a VPN connection established through that router on that particular real IP.
So the reason of having same IP on both Internet connection is simply enabling the backup link once the primary goes down and without making any change in the configuration at my end as well as site (where the VPN concentrator is risiding).
Now there is a limitation that i can have only 1 VPN connection from the reomote site.
=> How can i achieve real time backup connection (without manually changing the connection)? I have read about Tracking option in router but will it work in my case as i can have only 1 VPN connection!
I have seen this thing implemented in another scenario, where primary connection was terminating in E1 port of router and backup in FastEthernet ports with Internal network, using VLAN to isolate the internal traffic with that backup conection.
One machine can do the work of fifty ordinary men. No machine can do the work of one extraordinary man!
