Static domain name resolution configuration example
Network requirements
As shown in Figure 104, LB wants to access the host by using an easy-to-remember domain name rather
than an IP address.
Configure static domain name resolution on LB so that LB can use the domain name host.com to access
the host whose IP address is 10.1.1.2.

Configuration procedure
# Configure a mapping between host name host.com and IP address 10.1.1.2.
