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.
