[lug] Multihoming with Redhat

[bdoctor at ps-ax.com]

In terms of setting up the interface(s), you should look in 
/etc/sysconfig/network-scripts

In there you find files like ifcfg-eth0, ifcfg-lo, etc.  To use the same
interface with multiple IP addresses, copy the ifcfg-eth0 file to ifcfg-eth0:1.
Then, edit the device entry and change that to eth0:1, and the rest should
be obvious.  The device entry is critical, however.

If you need multiple static routes, create the file 
/etc/sysconfig/network/static-routes

Some samples for the static-routes:

eth0 net 192.168.0.0 netmask 255.255.255.0 gw eth0
eth0 net 192.168.1.0 netmask 255.255.255.0 gw eth0
eth0:1 net 207.2.3.4 netmask 255.255.255.248 gw eth0:1
