Configuring The Dns Proxy - HP 3600 v2 Series Configuration Manual

Configuration restrictions and guidelines
You can configure up to six DNS servers, including those with IPv6 addresses, in system view, and
•
up to six DNS servers on all interfaces of a device.
A DNS server configured in system view has a higher priority than one configured in interface view.
•
A DNS server configured earlier has a higher priority than one configured later in the same view.
A DNS server manually configured has a higher priority than one dynamically obtained through
DHCP. A name query request is first sent to the DNS server that has the highest priority. If no reply
is received, it is sent to the DNS server that has the second highest priority, and thus in turn.
• You can specify up to ten DNS suffixes.
Configuration procedure
To configure dynamic domain name resolution:
Step
1. Enter system view.
2. Enable dynamic domain
name resolution.
3. Specify a DNS server.
4. Configure a DNS suffix.

Configuring the DNS proxy

You can specify multiple DNS servers by using the dns server command repeatedly. Upon receiving a
name query request from a client, the DNS proxy forwards the request to the DNS server that has the
highest priority. If having not received a reply, it forwards the request to a DNS server that has the second
highest priority, and thus in turn.
To configure the DNS proxy:
Step
1. Enter system view.
2. Enable DNS proxy.
