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

Ok, both IPs are routed over eth0.

Same here.

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?

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?
