shared secret key

[CHAMPAGNE Eric TPC-SRD]

Hi

I have 2 DNS servers: ns1 and ns2

On ns2 there is a primary zone ( pft ) which is secondary on ns1.
To do this, i  don't need declare a secret key. It maches very well.

On ns1 i declare a primary zone ( bind9.pft ) which is secondary on ns2.
But now there isn't any zones transfert for bind9.pft between ns1 and ns2.
Then i declare a shared secret key on ns1 and ns2 and now, it maches very well.

??
I think i misunderstood something ..
Can anyone explain it ??

cheers
