Stateful SRP Switchover Overview

Stateful SRP switchover is the idea of reducing or eliminating single points of failure. When applied to the E Series router, stateful SRP switchover provides both hardware-specific and software-specific methods to ensure minimal downtime and ultimately improve the performance of your network.

For hardware components, Juniper Networks provides redundancy solutions to ensure that the router continues to operate in the event of a hardware fault. This redundancy can exist on various router models in the form of multiple power supplies, cooling fans, switching planes, routing engines and, in some cases, interfaces. Redundancy also allows for hot-swapping various components within your Juniper Networks router.

Note: For information about E Series hardware redundancy features, see the ERX Hardware Guide or the E120 and E320 Hardware Guide.
