Network router that efficiently switches between a primary data path and a backup data path |
摘要 |
A network router initially communicates over a primary data path. Upon detection of an error condition associated with the primary data path, the network router initiates a layer 2 switch such that the communication occurring over the primary data path is switched to a backup data path. The layer 2 switch is preferably transparent to a layer 3 portion of the network router.
