Redundant T1s with two ISPs

[twdave]

Currently each of our two lines run into separate routers, which lead to separate firewalls. In looking to revamp this and create some failover/redundancy. Is it possible to create an environment where if one of the T1s goes down, the other automatically accepts the traffic?

At this point, we would have to manually change gateways and DNS to do this.

Thanks for your help and suggestions.

BGP will do this for you, but you will need to terminate the T1's on the same router. Using BGP, you can balance the traffic between the two, so that you are getting the value of both, rather than having one T1 dark waiting for the primary to go down. The effect would still be the same, should one T1 take a dump, the other will take over with the only noticable effect being a slowdown in traffic if you are normally exceeding T1 bandwidth limits.
