Hi Darren,

 

You in luck that I had a similar situation with a client of mine about several years ago. What I decided to do is create BGP peering points between the 2 seperate ISPs. Such that the second ISP picks up the address block we are using on first ISP (The primary link). When a failure would occurs BGP would fail over the re-advertise the link out to the second ISP. As you can imagine this worked outwell because we didn't need to add additional addresses. Of course this all works if your ISP offers that type of service for the circuit you may have.

 

 

I hope this helps
