i've stumbled into a question whether it is possible to configure BIND
in a way that it responds to DNS SRV requests with the priority flag
changed depending on the IP address of the requesting party.
For example,
there are two SRV records for _foobar._tcp. One points to 10.0.1.2 and
the other to 10.0.2.2. The requesting party has the ip address
10.0.1.53. I would want to have the first one with the priority higher
than the second, which would allow me to split up the network by zones
each one having their own server with the rest of servers used only in
case of the prevalent zone server failure.
As variant:
Two views, fist with record
srv 10.0.1.2
srv 10.0.2.2
second:
srv 10.0.2.2
srv 10.0.1.2
Then set RRSET to FIXED.
Using two views is right, but the rest of this is very much not so.
No SRV-using application is going to treat the RR order in the answer
as significant. They will use the priority and weight fields as
described in RFC 2782 (or so one hopes). Those should be adjusted
appropriately in the two views.
