Configuration procedure
# Assign IP addresses to interfaces, as shown in Figure 23. (Details not shown.)
# Configure static routes or a routing protocol to make sure the devices can reach each other. (Details not shown.)
# Create DNS template dns.
<DeviceA> system-view [DeviceA] nqa template dns dns
# Specify the IP address of the DNS server 10.2.2.2 as the destination IP address.
[DeviceA-nqatplt-dns-dns] destination ip 10.2.2.2
# Specify host.com as the domain name to be translated.
[DeviceA-nqatplt-dns-dns] resolve-target host.com
# Set the domain name resolution type to type A.
[DeviceA-nqatplt-dns-dns] resolve-type A
# Specify 3.3.3.3 as the expected IP address.
[DeviceA-nqatplt-dns-dns] expect ip 3.3.3.3
# Configure the NQA client to notify the feature of the successful operation event if the number of consecutive successful probes reaches 2.
[DeviceA-nqatplt-dns-dns] reaction trigger probe-pass 2
# Configure the NQA client to notify the feature of the operation failure if the number of consecutive failed probes reaches 2.
[DeviceA-nqatplt-dns-dns] reaction trigger probe-fail 2
