Configuration procedure
Before doing the following configuration, make sure that:
The routes between the DNS server, Switch, and Host are reachable.
Necessary configurations are done on the devices. For the IP addresses of the interfaces, see the
figure above.
There is a mapping between domain name host and IP address 3.1.1.1/16 on the DNS server.
The DNS server works normally.
# Enable dynamic domain name resolution.
<device> system-view
[device] dns resolve
# Configure the IP address 2.1.1.2 for the DNS server.
[device] dns server 2.1.1.2
# Configure com as the DNS suffix
[device] dns domain com
Execute the ping host command on Switch to verify that the communication between Switch and Host
is normal and that the corresponding IP address is 3.1.1.1.
[device] ping host
Trying DNS server (2.1.1.2)
PING host.com (3.1.1.1): 56
