I currently have a 1600 router for Internet connectivity.
My company is considering another T1 from a different carrier, as a backup in case the primary T1 goes down.
If I wish to provide load balancing and especially an alternative failover route for traffic should my primary line go down (e.g. a line cut), what model would I need to upgrade to?
I'm assuming a 2600 or so, but would I need any special modules or IOS versions to accomplish this?
Thanks
