I would recommend that before addi
That answer seems to imply that when load is high enough on existing
caching servers the traffic will go to the others. Is that the case?
At what point does this occur?

Load balancing can also be used just to provide high availability for
your caching/resolver servers. Often times, even though a resolver
client will allow you to provide multiple resolving servers, if the
primary resolver goes down the delay until the next resolver is tried
often cripples applicat
Load-balancers are used for redundancy as well as performance management. In
the case of DNS, one way it might be used is to shunt client requests to the
servers that are up, thus side-stepping client-side resolve timeouts.

Hi Sasa,
For load balancing caching DNSs, you should try using anycast. When using
loadbalancers you may(I did) run into capacity issues.
Take a look at the quagga software package. It works great for load
balancing.
I have used both switches and anycast, and anycast is the way to go. Using

Right - I was just playing Devil's advocate with my question. I wasn't
the OP.
We don't use load balancing for DNS here. However, we do use the F5
BigIP for other load balancing purposes so I know they're good for load
balancing purposes and fairly stable.
Of course as Alan points out the an

Use LVS as freeware load balancer it's good enough.

Unless you're willing to spend a lot of money, load balancers are general
Yes, we've been using the ip sla feature for some time now, works well. Bgp/
ospf via quagga also are great solutions .
