actually, the way it works is:
1. Lookup local hosts (that is, host that are defined in the "ip host"
commands
2. Lookup with domain server (that is, if you have "ip name-server"
defined) If you have no ip domain-lookup
3. Appending the "ip domain-name" only resolves if you have a host defined
with the full domain name.

If you want to ping r1.ccie.com, then make this entry in your config:
ip host r1.ccie.com 10.1.1.1 (or whatever the ip address might be). Then,
you should be able to ping either r1 or r1.ccie.com
