Using Virtual Router Redundancy Protocol

One way to increase the reliability of the network is to provide backups of the critical components in the network. Oracle Solaris provides an administrative tool that configures and manages the use of the Virtual Router Redundancy Protocol (VRRP) to provide high availability. VRRP is an Internet standard protocol specified in RFC 5798.

Oracle Solaris 11.2 provides the proprietary Layer 3 VRRP to support the creation of VRRP routers over IPMP and InfiniBand interfaces and to enhance the existing support for VRRP in zones.

This chapter provides an overview of Layer 2 VRRP and proprietary Layer 3 VRRP in Oracle Solaris.

This chapter contains the following topics:

• About VRRP

• How VRRP Works

• About the Layer 3 VRRP Feature

• Comparing Layer 2 and Layer 3 VRRP

• Limitations of Layer 2 and Layer 3 VRRP
