Open Stack

I'm building an RDO instance of Open Stack on a single host.   My issue I'm looking for a networking solution.  My host has tthree NIC's.  I owuld like to use one NIC for administration, and the other two NIC's for VLAN type traffic.  What is the best networking solution for this environment?  In the KVM world, I would simply setup a bridge and have all my VM's utilize the bridge for networking traffic.
Is there an equivalent in the O/S world?   Any advice would be greatly appreciated.  

JT.
