Systems and methods to forward data frames are provided. A particular method may include evaluating address data of a first data frame at a first virtual bridge coupled to a first virtual machine of a first server computer of a plurality of server computers. Based upon the evaluation at the first virtual bridge, the first data frame may be forwarded to a second virtual bridge associated with an adapter that is coupled to the first virtual machine. The address data of the first data frame may be evaluated at the second virtual bridge. Based upon the evaluation, the data frame may be forwarded to a third virtual bridge configured to forward the data frame based upon the address data to a second server computer of the plurality of server computers.
