Abstract
Methods and systems for facilitating fault tolerance in a non-hot-standby configuration of a network routing system are provided. According to one embodiment, a method is provided for replacing an active processing engine with a non-hot-standby processing engine. Multiple processing engines within a network routing system are configured. The processing engines include an active processing engine having one or more software contexts, representative of a set of objects implementing a virtual router, for example, and a non-hot-standby processing engine having no pre-created software contexts corresponding to the one or more software contexts. Responsive to determining a fault associated with the active processing engine, the active processing engine is dynamically replaced with the non-hot-standby processing engine by creating replacement software contexts within the non-hot-standby processing engine corresponding to the one or more software contexts.
