add another 3mbps dsl connection

our company has 4mbps adsl connection using a cisco 1721 router, we want to add another 3mbps adsl connection. we want to integrate the new connection by buying another wic or buying another cisco router for load balancing ? what would be a better option ? how to do it ?

Re: add another 3mbps dsl connection

Getting a WIC card would be better and cost effective also.

Then you can use "ip per packet load balancing".

Re: add another 3mbps dsl connection

per packet loadbalancing would congest the 3mb dsl line while the 4mb dsl would still have room left. Further, per-packet load balancing can become quite cpu intensive.

If you want to load-balance you could inquire with your ISP's about setting up BGP sessions for load-balancing purposes. In that case they'd probably advertise their own networks and a default route to you spreading some of the load. Since it's not for advertising your routes to the internet they can assign you a private ASN to use, which fits into their policy unless you already have a public ASN you can use.

Another option is to use PBR to prefer one of the DSL links as long as it's available.
