Chapter 4 Configuring DNS
Configuring DNS Clients
The following example shows how to configure a default domain name and enable DNS lookup:
switch# config t
switch(config)# ip domain-name cisco.com 192.0.2.1 use-vrf management
switch(config)# ip domain-lookup
switch(config# copy running-config startup-config
Configuring Virtualization
You can configure a DNS client within a VRF. If you do not enter vrf configuration mode, your DNS
client configuration applies to the default VRF.
You can optionally configure a DNS client to use a specified VRF other than the VRF under which you
configured the DNS client as a backup VRF. For example, you can configure a DNS client in the Red
VRF but use the Blue VRF to communicate with the DNS server if the server cannot be reached through
the Red VRF.
BEFORE YOU BEGIN
Ensure that you have a domain name server on your network.
Ensure that you are in the correct VDC (or use the switchto vdc command).
