Appendix A

High Availability Features

High availability features include Routing Engine redundancy, graceful Routing Engine

switchover (GRES), nonstop bridging, nonstop active routing, graceful restart for

routing protocols, Virtual Router Redundancy Protocol (VRRP), and unified in-service

software upgrade (ISSU). Some high availability features are not supported by all

platforms and all PICs. For information about the first supported JUNOS release for

these features by PIC and platform, see the JUNOS High Availability Configuration

Guide.
