Abstract

See full text

An example method for determining an optimal forwarding path across a network having gateways configured to implement a plurality of logical networking protocols can include determining a path cost over a first logical network between each of the gateways and a source node and a path cost over the a second logical network between each of the gateways and a destination node. Additionally, the method can include determining an encapsulation cost difference between switching packets over the first and second logical networks. The method can also include determining an encapsulation overhead metric associated with one of the first or second logical networks, and weighting one of the first or second path cost by the encapsulation overhead metric. Further, the method can include selecting one of the gateways as an optimal gateway. The selection can be based on the computed path costs.
