7.6 VRRP/HiVRRP
The Virtual Router Redundancy Protocol (VRRP) is a protocol that enables
the system to respond to a problem with a router, e.g., when it has become
inoperable.
VRRP is used in networks with terminal devices that support only a single
entry for the default gateway. If the current default gateway becomes
inoperable, VRRP provides a redundant gateway for the terminal devices.
The Hirschmann company has further developed the VRRP into the
Hirschmann Virtual Router Redundancy Protocol (HiVRRP). With the
appropriate configuration, HiVRRP achieves switch-over times less than
400 ms.
Note: You will find detailed information on VRRP and HiVRRP in the
"Routing Configuration“ user manual.
