Distributed routing mechanisms for a virtual switch enabled by a trill-based fabric

摘要

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.

1. A system, comprising:
a first routing protocol engine (RPE) routing bridge (RBridge), comprising:
one or more local uplink ports configured to be coupled to a non-RBridge router; anda local processor for executing first logic, the first logic being configured to:
receive one or more data frames at the one or more local uplink ports;run routing protocols to enable layer-3 (L3) processing of the one or more data frames; andconfigure learned routes and routes passed from another RPE RBridge in the local processor; and a second RPE RBridge configured to serve as a backup to the first RPE RBridge, the second RPE RBridge comprising:
one or more second local uplink ports configured to be coupled to the non-RBridge router;a local processor for executing second logic, the second logic being configured to:
receive data frames at the one or more second local uplink ports;run routing protocols to enable L3 processing of the data frames; andconfigured learned routes and routes passed from another RPE RBridge in the local processor, wherein the first RPE RBridge and the second RPE RBridge are configured to be arranged in a first link aggregation group (LAG) cluster with the non-RBridge router, and wherein only the local uplink ports on the first RPE RBridge and the second RPE RBridge, to the exclusion of all other ports on the first RPE RBridge and the second RPE RBridge, are configured to run routing protocols that enable L3 support across the TRILL-enabled network.
