Note: To use nonstop bridging, you must first enable graceful Routing Engine switchover. |
Nonstop bridging enables a routing platform with redundant Routing Engines to switch from a primary Routing Engine to a backup Routing Engine without losing Layer 2 Control Protocol (L2CP) information. Nonstop bridging uses the same infrastructure as graceful Routing Engine switchover to preserve interface and kernel information. However, nonstop bridging also saves L2CP information by running the Layer 2 Control Protocol process (l2cpd) on the backup Routing Engine.
