DNS operation configuration example

Network requirements

As shown in Figure 9, configure a DNS operation to test whether Router A can translate the domain name

host.com into an IP address through the DNS server, and test the time required for resolution.

Configuration procedure

# Assign each interface an IP address. (Details not shown.)

# Configure static routes or a routing protocol to make sure the devices can reach each other. (Details not

shown.)

# Create a DNS operation.

<RouterA> system-view

[RouterA] nqa entry admin test1

[RouterA-nqa-admin-test1] type dns

# Specify the IP address of the DNS server 10.2.2.2 as the destination address, and specify the domain

name to be translated as host.com.

[RouterA-nqa-admin-test1-dns] destination ip 10.2.2.2

[RouterA-nqa-admin-test1-dns] resolve-target host.com

# Enable the saving of history records.

[RouterA-nqa-admin-test1-dns] history-record enable

[RouterA-nqa-admin-test1-dns] quit

# Start the DNS operation.

[RouterA] nqa schedule admin test1 start-time now lifetime forever

# Stop the DNS operation after a period of time.

[RouterA] undo nqa schedule admin test1

# Display the results of the DNS operation.

[RouterA] display nqa result admin test1
