Hi all,

I wounder if somebody could point me in the right direction for info on
setting up Split Horizons? Not sure if I have the terms correct.
Basicly I have two ISP lines and would like to use both for internet
traffic either load-balanced or by IP.

Thanks in advance.

Split Horizon as I know it is a technique used by some routing
protocols to prevent routing loops. I'm not sure it can be applied to
load balancing two ISPs.
Maybe you should look into specialized hardware to solve this issue.
Link load balancers like http://www.xrio.co.uk/qbalancer_range.aspx or
http://www.f5.com/products/bigip/isptm/
Another way to use different ISPs for Internet traffic is by applying
for a dedicated AS and IP-range and use BGP to route the traffic over
the different ISPs but this is very difficult to set up so unless
you're system is highly mission critical I'd go for dedicated hardware
solution.

Thanks for the replies.
I had thought about the F5 route but was trying to save costs.
This other way is a good thought jerker.
