Ddns Configuration Example With Peanuthull Server - H3C MSR 2600 Configuration Manual

Configuration procedure
Before configuring DDNS on Router, register with username steven and password nevets at
http://www.3322.org/, add Router's host name-to-IP address mapping to the DNS server, and make
sure the devices can reach each other.
# Create a DDNS policy named 3322.org, and enter its view.
<Router> system-view
[Router] ddns policy 3322.org
# Specify for DDNS update requests the URL address with the login ID steven and plaintext password
nevets.
[Router-ddns-policy-3322.org] url
http://members.3322.org/dyndns/update?system=dyndns&hostname=<h>&myip=<a>
[Router-ddns-policy-3322.org] username steven
[Router-ddns-policy-3322.org] password simple nevets
# Set the interval for sending DDNS update requests to 15 minutes.
[Router-ddns-policy-3322.org] interval 0 0 15
[Router-ddns-policy-3322.org] quit
# Specify the IP address of the DNS server as 1.1.1.1.
[Router] dns server 1.1.1.1
# Apply DDNS policy 3322.org to Ethernet 1/1 to enable DDNS update and dynamically update the
mapping between domain name whatever.3322.org and the primary IP address of Ethernet 1/1.
[Router] interface ethernet 1/1
[Router-Ethernet1/1] ddns apply policy 3322.org fqdn whatever.3322.org
After the preceding configuration is completed, Router notifies the DNS server of its new domain
name-to-IP address mapping through the DDNS server provided by www.3322.org, whenever the IP
address of Router changes. Therefore, Router can always provide Web service at whatever.3322.org.

mapping between its domain name and IP address. Router uses the DNS server to translate www.oray.cn
into its IP address.
