Abstract
In a network routing system, a control blade provides for redundancy and failover of virtual routers (VRs) instantiated by objects running on processing engines of the several virtual routing engines (VREs). When the control blade detects a failure of one processing engines, it may identify the virtual private networks (VPNs) and/or VRs operating on the failed processing engine. The control blade identifies a set of command lines corresponding with the identified VPNs and VRs, and replays the set of command lines with an identity of a new processing engine to recreate the identified VPNs and VRs on the new processing engine.
