Configuring Virtual Redundant Router Protocol
(VRRP)
You can use VRRP to provide fast automatic fail-over for hosts if the
default gateway fails when you have multiple routers to forward
traffic configured on your switch. This eliminates the single point of
failure inherent in the static default routed environment. A Master
VRRP router controls the IP addresses associated with the virtual
router and forwards packets sent to these IP addresses. The backup
router is always on standby. If the Master router fails, the backup
router takes over. Multiple virtual routers can be created per
interface. VRRP can be enabled or disabled globally or on an
interface basis.
Globally Enabling VRRP
You can globally enable VRRP from either the web agent or the CLI.
