Seconded -- multiple default gateways are definitely problematic.

You could set a metric on the second interface (eth1) prior to upping it so
that the primary has priority.  This doesn't completely remedy problematic
situations though. Example: if eth0 is downed at the switch, but not downed
on the host ... so the host will continue to try and use eth0.  A situation
in which serial remote management or physical vga/ip kvm access is helpful.
;)

Add "METRIC=30" to your ifcfg-eth1 file.
