loadbalancing two t1 lines and failover

Hi

We have a cisco 2610 Router with dual wic's.

Is there any sample config which supports Loadbalancing with two t1's.

and support failover between these two t1s.

Thanks

The link below explains the alternatives for parallel T1/E1 connections which might help you decide which one should you use. You can find the configuration guidelines for these alternatives on a separate documentation.

Will both links terminate on the same routers on the A & B side ?

What routing protocol are you using ?

Re: loadbalancing two t1 lines and failover

both the T1 connections terminate to the same router (Cisco 2610) .

Re: loadbalancing two t1 lines and failover

what routing protocol are you running ? and what version of IOS. ?

Re: loadbalancing two t1 lines and failover

If your routers are not stressed for CPU cycles, the cleanest and easiest load sharing solution is to configure multilink PPP. Just be careful because MLPPP does consume more CPU cycles than other approaches. You will also find varying levels of support in different IOS releases, so you'll want to test thoroughly before going into production (but, of course, you would do that regardless of the approach taken, right ?? :-)

Good luck and have fun!
