Ah... rc.local... thanks.

No, /etc/rc.local is absolutely the wrong place for any network setup routine.

Here are the results that you asked to see. I'm still quite curious as to how this is actually working.

[root dtweb02 sysconfig]# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface U 0 0 0 eth0 U 0 0 0 eth0 U 0 0 0 lo UG 0 0 0 eth0

Ok, both IPs are routed over eth0.

[root dtweb02 sysconfig]# ip route list dev eth0 scope link dev eth0 scope link dev lo scope link
default via dev eth0

Same here.

[root dtweb02 sysconfig]# ip address list
1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet scope host lo
4: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
link/ether 00:0e:7f:30:52:53 brd ff:ff:ff:ff:ff:ff
inet brd scope global eth0
inet brd scope global eth0
5: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 1000
link/ether 00:0e:7f:30:52:52 brd ff:ff:ff:ff:ff:ff

eth1 is not used anyway as it has no IP. Both IPs are assigned to eth0.
Curious that those different nets can be bound to one physical device.
Can someone shed any light on this?

There is no restrictions on binding IPs from multiple networks to a single nic. In fact, if multiple IPs from the same network are on one nic it can cause problems. in some situations.

And I couldn't get that last command to run. I tried ifcfg-ethX and ifcfg-eth0 and ifcfg-eth01 but all commands were not found. Perhaps they're not in the path?

Sorry, misunderstanding: I asked for the contents of /etc/sysconfig/network-scripts/ifcfg-eth0 and /etc/sysconfig/network-scripts/ifcfg-eth1, to see how you configured both ethernet devices. Additional, what does "ifconfig -a" report?
