Configuring VRRP
Virtual Router Redundancy Protocol (VRRP) is used to provide fast-fail
over for hosts if the default gateway fails. This eliminates the single point of
failure inherent in a network with statically configured default routes. The
VRRP protocol defines an election process that will determine a Master and
a Backup router. The Master router will forward all packets destined for the
IP Address associated with the virtual router. The Backup router monitors
the availability of the Master router and will assume Mastership in the event
that the Master router fails.
The VRRP protocol is described in detail in RFC 2338.
This section contains procedures for the following tasks:
■ Globally Enabling VRRP
■ Enabling VRRP on an Interface
■ Creating a VRRP Virtual Router
■ Displaying VRRP Statistics
■ VRRP Configuration Considerations
Globally Enabling VRRP
VRRP can be enabled (or disabled) globally using the Web or CLI.
Disabling VRRP globally will cause all virtual routers to transition to the
Initialize state. VRRP is globally enabled by default.
You can globally enable VRRP from either the Web Agent or the CLI.
Web Agent
Procedure
To globally enable VRRP using the Web Agent:
1. In the navigation pane, expand the Routing > IP > Configuration
folders, and then click Global Configuration.
The IP Global Configuration Web page is displayed in the content pane.
See Figure 12-35.
