516 CHAPTER 38: IPV6 BASICS CONFIGURATION
Configuring Dynamic
IPv6 Domain Name
Resolution
If you want to use the dynamic domain name function, you can use the following
command to enable the dynamic domain name resolution function. In addition,
you should configure a DNS server so that a query request message can be sent to
the correct server for resolution. The system can support at most six DNS servers.
You can configure a DNS suffix so that you only need to enter some fields of a
domain name and the system can automatically add the preset suffix for address
resolution. The system can support at most 10 DNS suffixes.
Follow these steps to configure dynamic IPv6 domain name resolution:
n
The dns resolve and dns domain commands are the same as those of IPv4 DNS.
For details about the commands, refer to “DNS Configuration” on page 971.
