VPN Failover within the same ASA

Hi Everyone,

I'm working out a concept here and want to know if this can be done. On an ASA I would like to have 2 different interfaces connect to 2 different ISP's - one primary, one backup. As well I will be running VPN tunnels across the links.

What I want to know is if I have a tunnel established over ISP A to our remote site, and it fails, is there a way to have the state information and tunnel moved over to ISP B, on the same ASA device?

Thanks!

Hi,

You need to go with tracking the primary ISP config.. someone posted the attached longtime back and I saved it..(so if this is helpful..say thanks to them..;-))

Also, I don't think 'state' information will moved over withouttearing down the existing connections..

Thanks MS,

Unfortunately I have the need of being able to send the state information over to the other port as well - if possible.

I know there is "juni***" gear that can do this, but I'm not sure if the ASA's can or cannont - currently we're running ASA's.

My goal is to not only have a backup link for the sites, but aslo the VPN tunnel moved over automatically as well - as the reestablishment of these sessions cause great issues with the customers...

Thanks!

This would actually require some functionality that I don't believe is in the client either. The client has to know to tunnel to a different IP address to meet this need. Correct? There is an option for backup servers, but I don't think that is stateful.

Hi Paul,

That is correct. The client needs to tunnel through a different ISP which would mean that there is a different ISP in use. I'm not sure if it's possible, but thought I would see if anyone has come across this before...
