Stateful Switchover. Ch. 9 High Availability CIS 187 Multilayer Switched Networks CCNP Stateful Switchover (SSO) works here and it minimize the network unavailable time after a switchover Stateful switchover (SSO) refers to the capability of the control plane to hold configuration and various states during this switchover, and to thus effectively reduce the time to utilize the newly failed-over control plane

Additionally, the periodic timer is restarted for interfaces that use keepalive messages to verify link integrity Cisco Nonstop Forwarding (NSF) works with the Stateful Switchover (SSO) feature to minimize the amount of time a network is unavailable to users following a switchover

Cisco 9500 StackWise Virtual Configuration

Stateful switchover (SSO) is a mechanism used to take control from a failed Route Processor (RP) while maintaining connectivity in a networking device, such as a router or switch It ensures that the standby RP is ready to take over processing duties immediately in the event of an RP failure, minimizing disruption to network services.. Stateful Switchover (SSO) is a redundancy feature that allows a Cisco device with two route processors to synchronise router configuration and control plane state information

Stateful Switchover PDF Computer Network Protocols. Configuring Nonstop Forwarding with Stateful Switchover In particular, the GE interfaces on the RPs are reset across switchovers and do not support SSO.

Cisco Nonstop Forwarding with Stateful Switchover Deployment Guide. The main objective of NSF SSO is to continue forwarding IP packets following a Route Processor (RP) switchover. The processing of mirroring this information between route processors is known as checkpointing
