Bind forwarders

[Forrest Aldrich]

There doesn't seem to be much documentation on the use of Forwarders.

For example, in our situation, we have PoPs all over the US which are 
running their own full secondary DNS.

We've are regularly subjected to Visual Networks evaluations, etc., and we 
thought that our DNS performance would improve if we were to utilize 
forwarders within our own network cloud.  So, we have primary servers on 
east and west coasts that are rigged with lots of RAM, etc.

I wanted to get more of an idea about the forwarder algorithm.  I know it's 
supposed to be "better" in Bind-9.  And the ideal application of a 
forwarder setup.

For example, I thought that if we had different PoPs forward to other busy 
PoPs before our Primary DNS, that it might perform better.  But that 
becomes difficult to manage.

Any pointers would be appreciated.
