Step 9
Configuring Virtualization on a DNS Client
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).
