As shown in Figure 39:
• Specify Device A as the DNS server of Device B (the DNS client). Device A acts as a DNS proxy.
The IPv6 address of the real DNS server is 4.1.1.1.
• Configure the IP address of the DNS proxy on Device B. DNS requests of Device B are forwarded
to the real DNS server through the DNS proxy.

Configuration procedure
Before performing the following configuration, ,make sure Device A, the DNS server, and the host can
reach each other and the IPv6 addresses of the interfaces are configured as shown in Figure 39.
1. Conf
igure the DNS server:
The configuration might vary with DNS servers. When a PC running Windows Server 2000 acts
as the DNS server, see "Dynamic domain name resolution c
onfiguration example" for
configuration information.
2. Configure the DNS proxy:
# Specify the DNS server 4.1.1.1.
<DeviceA> system-view
[DeviceA] dns server 4.1.1.1
# Enable DNS proxy.
[DeviceA] dns proxy enable
3. Configure the DNS client:
<DeviceB> system-view
# Specify the DNS server 2.1.1.2.
[DeviceB] dns server 2.1.1.2
Verifying the configuration
# Use the ping host.com command on Device B to verify the connection between the device and the host
is normal and that the translated destination IP address is 3.1.1.1.
[DeviceB] ping host.com
Ping host.com (3.1.1.1): 56 data bytes, press CTRL_C to break
56 bytes from 3.1.1.1: icmp_seq=0 ttl=255 time=1.000 ms
56 bytes from 3.1.1.1: icmp_seq=1 ttl=255 time=1.000 ms
