We have a setup with severals Bind in a row:
hidden master
customer
(software unknown)
|
|
V
our incoming nameserver
Bind 9.9.5
|
|
V
our distribution nameserver
Bind 9.9.5
|
|
V
our anycast nameserver
Bind 9.11.3+dfsg-1ubuntu1.8
According to our logs, the was no IXFR-style AXFR. The IXFR from the
customer to us was around 1.87GB (at least on the wire).
>From our "incoming" nameserver to our "distribution" nameserver, and
from there to our Anycast node it was around 2.37G.
See log details below.
Thanks
