I am relative newbie to routing & networking
I am trying to use a debian box for load balancing & failover. I found this guide which lays down the steps -

It seems to be a nice & simple guide, but I have a few questions.1)The failover seems to be accomplished by using the gc_timeout parameter - by setting it to a low value like 10. Won't this cause the route caches to be destroyed & reacreated every 10 seconds - i.e won't this be rather inefficient?
2) The guide has some stuff common to the guide published at lartc site.

there are significant differences. The lartc guide adds entries to the the rt_tables & routes based on those - is that not neccessary.3) I am a little confused about dns servers in the whole scenario. Many a times a DNS Server can be used only when you are connected through a particular ISP - i.e. it's the ISP's private DNS Server. So what do we do in the load balancing/failover case to ensure that the DNS query goes to the right DNS Server?
Not sure if this is the right forum for this question. If not, please advise as to what's a better place for this question. The lartc mailing list & IRC seem to be dead. And I didn't get any responses in comp.os.linux.networking.
