About 7000 and 8000 Series Device High Availability
With 7000 and 8000 Series device high availability, you can establish redundancy of networking functionality
and configuration data between two peer devices or two peer device stacks.
You achieve configuration redundancy by configuring two peer devices or two peer device stacks into a
high-availability pair to act as a single logical system for policy deploys, system updates, and registration.
The system automatically synchronizes other configuration data.
Static routes, non-SFRP IP addresses, and routing priorities are not synchronized between the peer devices
or peer device stacks. Each peer device or peer device stack maintains its own routing intelligence.
