That is strange terminology. "Equal-cost load balancing" is a better description. Basically if multiple routes exist for the same destination, traffic is distributed over them. There is a patch for equal-cost load balancing. See list archives. > 1 Layer 2 aggregation. The interface driver round robins all packets > for the destination among the available interfaces.

The kernel routing table still needs to be able to able to hold multiple routes for the same destination. You forgot some options: #3 Round-robin DNS. Works well for many application. Very simple and well understood. #4 Use a single faster interface. Throw those 100BT cards away and get a gigabit card. > Thank you, > > Yours sincerely. > > > Stanley Hopcroft > IP Australia > > +61 2 6283 3189 > +61 2 6281 1353 FAX > Tom To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
