Hi Guys

I've been tasked to find out how failover can be accomplished for a
remote site.
The remote site has unstable lines, and therefore they have two lines
operating from different providers.
There are a site-to-site set up that only uses one of the lines, so if
that goes down, the vpn is down.
The thought was then, because of the two lines, that it would be nice to
have it switch between the two lines on the remote site.

Question is, how do we accomplish this?
It's also important to note, that the best solution is not a load
balancing thing, it's primarely a failover that's necessary.
