For reference:

As far as I know, bridged networking is only really documented for 
virtualization, but this link covers creation of a bridge and adding a 
single interface to it, and disabling iptables for bridges:
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5/html/Virtualization/sect-Virtualization-Network_Configuration-Bridged_networking_with_libvirt.html

You'd simply set up both eth2 and eth3 as eth0 is set up in that example.

The options available in ifcfg files are documented in:
