can two default gateway load balance ?

Dear All,

I have a costumer that have 2 ADSL line to the internet, and they want to either load balance the line or combine the bandwidth of the 2 ADSL line. Somebody once tell me that if you put 2 default GW with the same metric in your router, it supposed to be able to load balance it. Anyone can tell me whether this is true or not ?.

Thanks and best regards

Re: can two default gateway load balance ?

You cannot load balance two ADSL lines unless you run BGP -of which I am sure that is not available.

Another option: install a router that has three ethernet ports. One to the LAN and the other x-connected to the ADSL modems. Set a default route on the router to each ethernet port (for example):

ip route e1

ip route e2

The router will do per-destination routing in a round-robin fashion and the max throughput will be one ADSL link.

Good luck
