Static routes as failover

We have a site that has a router and frame connection. There is a Cisco vpn 3002 client with a dsl connection.

In case the frame goes down, we want to forward traffic through that 3002, but want the frame to be the primary connection if it comes back up.

A.) Do I need to do a routing protocol like RIP (it doesn't support any)

B.) Will static routes on the router be sufficient like:

ip route 0.0.0.0 0.0.0.0 10.50.1.1

ip route 0.0.0.0 0.0.0.0 10.50.1.2 20

If the static routes will work, will the router always try to send traffic out of the first and then the next? In other words, if the frame comes back up will the traffic automatically go out of that?

Thanks!

Re: Static routes as failover

As long as the 2 static routes are comparable, as they are now, then yes, the primary will be used when the next hop (10.50.1.1) comes back online.

Just to add to Victor's post. Generally a floating static such as

ip route 0.0.0.0 0.0.0.0 10.50.1.2 20

you would tend to set the AD to 250 or thereabouts ie.

ip route 0.0.0.0 0.0.0.0 10.50.1.2 250

this is just to ensure that any dynamic routing protocol traffic would be used before this kicks in which is generally what you want. Not a bad habit to get into.
