CHAPTER 24
Virtual Router Redundancy Protocol
The BNT RackSwitch G8124 (G8124) supports IPv4 high-availability network topologies through
an enhanced implementation of the Virtual Router Redundancy Protocol (VRRP).
Note – BLADEOS 6.5 does not support IPv6 for VRRP.
The following topics are discussed in this chapter:
“VRRP Overview” on page 332. This section discusses VRRP operation and BLADEOS
redundancy configurations.
“Failover Methods” on page 334. This section describes the three modes of high availability.
“BLADEOS Extensions to VRRP” on page 336. This section describes VRRP enhancements
implemented in BLADEOS.
“Virtual Router Deployment Considerations” on page 337. This section describes issues to
consider when deploying virtual routers.
“High Availability Configurations” on page 338. This section discusses the more useful and
easily deployed redundant configurations.
