Cisco 886VA - Multiple PPPoE Line Load Balancing

Dear Cisco Community,

due to the need of increased bandwidth a customer ordered three ADSL6000/576Kbit lines from the same ISP. Dial-in is done with PPPoE and the IP is not static.

- Is it possible to load balance between the three ISP lines with this router as the Cisco 886VA-K9 (Advanced IP Services) doesnt support PFR/OER I want to load balance per session, meaning each TCP session takes the same path, the next TCP session takes second path, next TCP session takes third path, then first path again and so on.

- I did read the tutorials avaiable, but they don't discuss how the lines are used in round-robin fashion, just how to distribute different traffic on different lines. (https://supportforums.cisco.com/document/32186/dual-internet-links-nating-pbr-and-ip-sla?page=1) or (http://www.cisco.com/c/en/us/support/docs/ip/network-address-translation-nat/100658-ios-nat-load-balancing-2isp.html)

- How would you solve this challenge?

Hi lauresfrank,

Hi lauresfrank,

Did you ever manage to solve this challenge?

Hi, i used three default

Hi, i used three default routes, each point to a different gateway IP. Load balancing over those three lines is very equal.
