Configuration procedure
Before configuring DDNS on Router, perform the following tasks:
• Register with username steven and password nevets at http://www.oray.cn/.
• Configure a DDNS policy to update the mapping between the router's FQDN and IP address.
• 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 the URL address, username, and password for DDNS update requests.
[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 1/0/1 to enable DDNS update. The mapping between
whatever.gicp.cn and the primary IP address of GigabitEthernet 1/0/1 will be dynamically updated.
[Router] interface gigabitethernet 1/0/1
[Router-GigabitEthernet1/0/1] ddns apply policy oray.cn fqdn whatever.gicp.cn
