Abstract
Some embodiments described herein provide a combination of a layer 3 (L3) hop with layer 2 (L2) bypass/fail-to-wire in a network device. Specifically, some embodiments place the network device between two routers, thereby becoming a L3 hop between the two routers. The existing route between the two routers is preserved by using L2 bypass through the network device. If the network device fails, then the physical fail-to-wire will be engaged, removing its L3 hop, but preserving the L2 bypass.
