Yes, this works just fine... I got two named listening on different
IP-alias, with using their own named.conf files.

The problem is that VIP interface (or alias) does not have named
listening-on. ie:
10.1.1.2:53 (VIP) ---> 10.1.1.3:53 (RIP, ip-alias)
---> 10.1.1.4:53 (second RIP, ip-alias)
If named is not listening on 10.1.1.2, packets are being rejected,
of course if I start another named instance on 10.1.1.2; it will respond
however it will not loadbalance on 10.1.1.3 and 10.1.1.4.
Any ideas?
