19 Configuring VRRP
The Virtual Router Redundancy Protocol (VRRP) is a standard router redundancy protocol supported in IP
version 4. It is based on RFC 3768 and provides redundancy by eliminating the single point of failure
inherent in a default route environment.
Note. RFC 3768, which obsoletes RFC 2338, does not include support for authentication types. As a
result, configuring VRRP authentication is no longer supported in this release..
In This Chapter
This chapter describes VRRP and how to configure it through the Command Line Interface (CLI). CLI
commands are used in the configuration examples; for more details about the syntax of commands, see the
OmniSwitch CLI Reference Guide.
This chapter provides an overview of VRRP and includes information about the following:
• Virtual routers—see “Creating a Virtual Router” on page 19-8.
• IP addresses for virtual routers—see “Specifying an IP Address for a Virtual Router” on page 19-9.
• VRRP advertisement interval—see “Configuring the Advertisement Interval” on page 19-10.
• Virtual router priority—see “Configuring Virtual Router Priority” on page 19-10.
• Preempting virtual routers—see “Setting Preemption for Virtual Routers” on page 19-11.
• VRRP traps—see “Setting VRRP Traps” on page 19-12.
• VRRP tracking—see “Creating Tracking Policies” on page 19-13.
• Verifying the VRRP configuration—see “Verifying the VRRP Configuration” on page 19-14.
