How to Configure the CSS to Load Balance DNS Servers


For example,Basically we need to enter the following commands:

Configure the DNS server zone for zone-based DNS. Specify the zone, tier number, and an optional text description:

- CSS (config)# dns-server zone 0 tier1 ""

Configure the CSS to act as a DNS server:

- CSS (config)# dns-server

Add the DNS records as needed:

- CSS (config)# dns-record a www.home.com 192.x.1.1 15 single kal-ap 172.x.25.1 50


Configure DNS as primary to point to itself:

CSS (config)# dns primary 172.x.1.90

(circuit VLAN1 - ip address 172.3x.1.90 / 24)

This is just an example but it is basically all you need to configure DNS on the box.

A different use on the box for DNS would be basically to load balance the DNS traffic

between DNS servers. This is however something different to configure on the box and more
