CHAPTER 14
High Availability
RackSwitch G8000s support high-availability network topologies through Layer 2 Failover and an
enhanced implementation of the Virtual Router Redundancy Protocol (VRRP).
The following topics are discussed in this chapter:
 “Layer 2 Failover” on page 192. This section discusses trunk failover without using VRRP.
 “VRRP Overview” on page 196. This section discusses VRRP operation and BLADE OS
redundancy configurations.
 “Failover Methods” on page 198. This section describes the three modes of high availability.
 “BLADE OS Extensions to VRRP” on page 200. This section describes VRRP enhancements
implemented in BLADE OS.
 “Virtual Router Deployment Considerations” on page 201. This section describes issues to
consider when deploying virtual routers.
 “High Availability Configurations” on page 202. This section discusses the more useful and
easily deployed redundant configurations.
