Re: Internet Traffic load balancing

Yes each route is equal, but more point to one exit point vs. another. Try it, it works.

>> This will cause CEF to load balance in a ratio of 5:2 for gateways 10.0.0.1 and 20.0.0.2 respectively. The ratio won't be exact unless your traffic flows are evenly distributed. To get close to the result you want you can add or remove additional routes to adjust the ratio as you need.
