In one embodiment, a system includes a routing protocol engine (RPE) RBridge which includes a local uplink port configured to be coupled to a router, a local processor for executing logic, and logic configured for: receiving a data frame at the local uplink port, running routing protocols to enable L3 processing of the data frame, connecting to a LAG cluster, and configuring learned routes and routes passed from another RPE RBridge in the local processor. In more embodiments, methods for providing L3 processing in a TRILL-enabled network include receiving a data frame at a local uplink port of a RBridge enabled with a RPE to enable L3 processing, running routing protocols to provide L3 processing of the data frame, and configuring learned routes and routes passed from any other RPE RBridges. The RPE RBridge may be connected to a router or to a first server and a second server.
