Miercom Lab Testing for Edge and Core Routers: Cisco Nonstop Forwarding with Stateful Switchover drastically reduces mean time to repair (MTTR)
The testing covers analysis and performance validation tests of its Cisco Nonstop Forwarding (NSF) with Stateful Switchover (SSO) capabilities, which are part of Cisco Globally Resilient IP Technologies. The goal of testing was to validate switchover times during a route processor failure on three Cisco edge routers: the Cisco 12000 Series Router, Cisco 10000 Series Router and Cisco 7500 Series Router , each of which displays different strengths at the edge. Tests were conducted with 600 interfaces; 2,000 OSPF or IS-IS routes; and 65,000 BGP routes on each router.

1) Cisco Nonstop Forwarding with Stateful Switchover drastically reduces mean time to repair (MTTR)
2) Delivered zero route flaps with BGP, OSPF, IS-IS and static routes during recovery
3) Maintained state and showed zero link flaps during recovery for multiple protocols including Frame Relay, ATM, HDLC, PPP and Ethernet
4) Cisco 12000 experienced no packet loss during route processor switchover, resulting in uninterrupted voice and video transmission
