When looking at a large number of OSPF neighbors while troubleshooting
it can take a lot of time to determine what sites you are looking at.
A quick way to determine sites that are in (or not) in your list of OSPF neighbors is to show them by name.
If you have a good naming convention, the process of setting these up in DNS by
name will also allow you to telnet by name with little brain strain.
It's very simple to setup, and gives the benefit of clarity in enterprise networks
as well as small networks.
The commands are below.
***Note items in red should be replaced with information specific to your environment.
1. "ip domain-name mydomain.com"
This is to allow appending of the domain name for searches via your DNS server.
2. "ip name-server 192.168.1.10"
This is to define your DNS Server.
3. "ip ospf name-lookup"
This is the command that controls showing the name of a device instead
of the IP Address (Router-ID).
