Configuring IP Routing
Configuring Virtual Router Redundancy Protocol
(VRRP)
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.
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 (see State in table 8-3). 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. Select Global Configuration from the Routing > IP >
Configuration group on the Web Agent window. The IP
Global Configuration dialog box opens (Figure 6-61).
