Cisco Cisco IOS Software Release 12.4(4)T

If there is no domain list, the domain name that you specified with the ip domain name global 
configuration command is used. If there is a domain list, the default domain name is not used. The 
ip domain list command is similar to the ip domain name command, except that with the 
ip domain list command you can define a list of domains, each to be tried in turn until a match is found. 

The following example shows how to define cisco.com as the default domain name for a VPN named 
vpn1. The domain name is only used for name queries in the specified VRF.

ip domain name vrf vpn1 cisco.com

Any IP hostname that does not contain a domain name (that is, any name without a dot) will have the dot 
and cisco.com appended to it before being looked up.

The following example shows how to define two static hostname-to-address mappings in the host cache 
for vpn2 and vpn3:

ip host vrf vpn2 host2 10.168.7.18

ip host vrf vpn3 host3 10.12.0.2
