FIGURE 2 Basic controller and site communication
To add a DNS policy, you must also define the DNS real server and VIP on the ServerIron ADX as
shown in the following example.
!
server real <dns-rs-name> <dns-ip-addr>
port dns
port dns zone "<domain-name>"
port dns proxy
port http
port http url "HEAD /"
!
!
server virtual <dns-vs-name> <vip-ip-addr>
port dns
port http
bind dns dns-rs dns
bind http dns-rs http
!
gslb dns zone <domain-name>
host-info www http
Use server real <dns-rs-name> <dns-ip-addr> for a local DNS server. Use server remote-name
<dns-rs-name> <dns-ip-addr> for a remote DNS server. The host-info defines an enabled
application in the DNS zone. For example, you can also specify host-info ftp ftp.
