SSO Aware HSRP
SSO Aware HSRP offers continuous data packet forwarding during a supervisor engine switchover
without a path change to the standby HSRP router. During supervisor engine switchover, NSF with SSO
continues forwarding data packets along known routes using the HSRP virtual IP address. When both
supervisor engines fail on the active HSRP router, the standby HSRP router takes over as the active
HSRP router. It further extends reliability and availability offered by the NSF with SSO to Layer 3. SSO
aware HSRP is available for Supervisor Engine IV, V, and V-10GE on Catalyst 4507R and 4510R chassis
with supervisor redundancy.
