There are several ways to achieve some form of load balancing....
1. Get another router to sit directly behind the 2 T1 routers and act as the default gateway for your LAN. Use this router to policy-route traffic across the two T1s. You won't achieve true load-balancing, but you can at least segment your "junk" traffic to one T1 and your "business critical" traffic to another. Plus, you have an automated failover solution in that if one T1 goes down, the router can automatically redirect traffic to the still active T1 router. 2. You'll have to use BGP to create a peering between you and your provider. Then, use BGP to "influence" which T1 will receive traffic. I doubt your provider will do this for you though as it's a lot of work for a "small" customer J. 3. Combine the circuits into one router and ask your provider to run MLPPP with you (this is probably the best solution). 4. Buy a load balancer like Radware or the like and let it manage the load balancing for you. Hope this helps, Aaron T.

We moved a T1 from our remote office to our main office and now have the two T1's running. What we would like to do is load balance or combine the two T1's to create a bigger internet pipe for our main office. At the moment we have two different routers, Adtran NetVanta 3200 and a Cisco 1841 T1, can we take the two different routers and create the bigger pipe or will we need to purchase a router that will allow us to do this? ---_______________________________ Cameron Cooper IT Director - CompTIA A+ Certified Aurico Reports, Inc Phone: 847-890-4021 Fax: 847-255-1896 ccoo...@aurico.com ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
