IOS SLB dns probe

dario.didio · ‎12-04-2008

Hi,

I'm trying to configure a DNS probe using IOS SLB, but it's not working.

I followed the manual on how to configure a DNS probe, but it just doesn't make any sense.

When using DNS probes on an ACE, you give a hostname which the DNS server should resolve to a configured IP Address.and configure an ip address, which makes sense.

On the IOS SLB, it is not the case. Two variables can be configured:

Router(config-slb-probe)# address ip-address]

(Optional) Configures an IP address to which to send the Domain Name System (DNS) probe.

Router(config-slb-probe)# lookup [ip-address]

(Optional) Configures an IP address of a real server that a Domain Name System (DNS) server should supply in response to a domain name resolve request.

What am I missing. Could someone please clearify??

Tnx!

To verify that a probe is configured correctly, use the show ip slb probe command:

Router# show ip slb probe
