Configuration procedure
Before configuring DDNS on Router, register with username steven and password nevets at
http://www.oray.cn/, 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 oray.cn and enter its view.
<Router> system-view
[Router] ddns policy oray.cn
# Specify for DDNS update requests the URL address with the login ID steven and plaintext password
nevets .
[Router-ddns-policy-oray.cn] url oray://phservice2.oray.net
[Router-ddns-policy-oray.cn] username steven
[Router-ddns-policy-oray.cn] password simple nevets
# Set the DDNS update request interval to 12 minutes.
[Router-ddns-policy-oray.cn] interval 0 0 12
[Router-ddns-policy-oray.cn] quit
# Specify the IP address of the DNS server as 1.1.1.1.
[Router] dns server 1.1.1.1
# Apply the DDNS policy to Ethernet 1/1 to enable DDNS update and dynamically update the mapping
between whatever.gicp.cn and the primary IP address of Ethernet 1/1.
[Router] interface ethernet 1/1
[Router-Ethernet1/1] ddns apply policy oray.cn fqdn whatever.gicp.cn
After the configuration is completed, Router notifies the DNS server of its new domain name-to-IP address
mapping through the PeanutHull server, whenever the IP address of Router changes. Therefore, Router
can always provide Web service at whatever.gicp.cn.
