R2511-HP MSR Router Series Layer 3 - IP Services Configuration Guide(V5)

91
Configuration prerequisites
Visit the website of a DDNS service provider, register an account, and apply for a domain name for the
DDNS client. When the DDNS client updates the mapping between the domain name and the IP address
through the DDNS server, the DDNS server checks whether the account information is correct and
whether the domain name to be updated belongs to the account.
Configuration procedure
To configure a DDNS policy:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Create a DDNS policy and
enter its view.
ddns policy policy-name By default, no DDNS policy is created.
3. Specify a URL address for
DDNS update requests.
url request-url
By default, no URL address is specified for
DDNS update requests.
4. Associate an SSL client policy
with the DDNS policy.
ssl client policy
policy-name
Optional.
By default, no SSL client policy is
associated with the DDNS policy.
This step is only effective and a must
for HTTP-based DDNS update
requests. For SSL client policy
configuration, see Security
Configuration Guide.
5. Specify the interval for sending
update requests.
interval days [ hours
[ minutes ] ]
Optional.
By default, the time interval is one hour.
The URL address for an update request can start with http://, https://, or oray://.
• http:// indicates the HTTP-based DDNS server.
• https:// indicates the HTTPS-based DDNS server.
• oray:// indicates the TCP-based PeanutHull server.
Applying the DDNS policy to an interface
After you apply the DDNS policy to an interface and specify the FQDN for update, the DDNS client
sends requests to the DDNS server to update the mapping between the domain name and the primary
IP address of the interface at the specified interval.
Configuration prerequisites
• Specify the primary IP address of the interface and make sure the DDNS server and the interface
can reach each other.
