the second choice is not an option to aggregate links. Actually, it may even prevent load sharing to happen and bring serious problebms because routing will be done over the external address only.

The choice is between MLPPP and regular CEF load sharing algorithm. The first is more CPU intensive, add a small delays makes load balancing perfect without unwanted consequences. However, for simplicty, unless you have a good reason not to use, I would suggest the default CEF load sharing.

Hope this helps, please rate post if it does!
