IXFR under bind 8.2.1

[James Hall-Kenney]

Hi y'all,

I think I've missed the point somewhere on ixfr under bind 8.2.1.  I can't
seem to find any references to how to put it together other than the syntax
for the various named.conf options.  I have a master and a slave configured
as per below.

The way I read the slaves log indicates that it is trying an ixfr but the
master always shows axfr.

On master server ns1.myzone.org.nz (10.184.0.29)

options {
         directory "/var/opt/dns";
         maintain-ixfr-base yes; // not sure if this is required on the
                                 // master??
         notify yes;
};


server 10.184.0.29 {
        support-ixfr yes;   // is this required on both slave and master?
};



On slave server ns2.myzone.org.nz (10.184.0.29)

options {
         directory "/var/opt/dns";
         maintain-ixfr-base yes;
};

server 10.184.0.28 {
         support-ixfr yes;      
};

zone "myzone.org.nz" in {
                      type slave;
                      file "db.myzone.org.nz";
                      ixfr-base  "db.myzone.org.nz.ixfr";
                      masters { 10.184.0.28; };
};
