Chapter 25. Virtual Router Redundancy Protocol
The BNT RackSwitch G8000 (G8000) supports IPv4 high-availability network
topologies through an enhanced implementation of the Virtual Router Redundancy
Protocol (VRRP).
Note: IBM Networking OS 6.8 does not support IPv6 for VRRP.
The following topics are discussed in this chapter:
• “VRRP Overview” on page 298. This section discusses VRRP operation and
IBM N/OS redundancy configurations.
• “Failover Methods” on page 300. This section describes the three modes of high
availability.
• “IBM N/OS Extensions to VRRP” on page 302. This section describes VRRP
enhancements implemented in N/OS.
• “Virtual Router Deployment Considerations” on page 303. This section describes
issues to consider when deploying virtual routers.
• “High Availability Configurations” on page 304. This section discusses the more
useful and easily deployed redundant configurations.
