• Add the domain name whatever.gicp.cn at http://www.oray.cn/.
• Add the router's host name-to-IP address mapping to the DNS server.
• 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 GigabitEthernet 2/0/1 to enable DDNS update. The mapping between
whatever.gicp.cn and the primary IP address of GigabitEthernet 2/0/1 will be dynamically updated.
[Router] interface gigabitethernet 2/0/1
[Router-GigabitEthernet2/0/1] ddns apply policy oray.cn fqdn whatever.gicp.cn
After the configuration is completed, the router notifies the DNS server of its new domain name-to-IP
address mapping through the PeanutHull server, whenever its IP address changes. Therefore, the
router can always provide Web service at whatever.gicp.cn.
