How can I configure ifcfg-eth0?

Does OS create ifcfg-eth0? or all of them are configured manually?
What does the "NETWORK=xxx" mean?

Yes the OS creates the file and you can configure manually.
It means in which network you belong to by the IP address. For example your IP is 10.2.20.5 then NETWORK=10.2.20.0.

The ifcfg-eth0 type files are created in response to configuring the interfaces wi thte redhat scripting scheme "system-config-network". Also during installation these interfaces may be recognized and the file created. You should NOT edit these manually. Errors from manual editing may cause severe and difficult to diagnose problems.

These files are shell variable definitions which are included and used in the scripts (ifup, ifdown, ifcfg, /etc/sysconfig/network-scripts/*, ...). To gain a detailed understanding for how the NETWORK variable is used, view the scripts.

It seems to be used for route table and ipsec setup among others.
