VRRP CONFIGURATION
In some environments the networks connect to each other through one router. This single
router is therefore a potential failure point, which could disconnect a whole network from the
rest.
The VRRP protocol permits several routers to be presented to clients with a common single
virtual IP address, controlling the routers included in the virtual router, which is always the
one that effectively provides the service, thereby providing redundancy to clients in a
transparent manner. A master is selected from among all the routers, whereas the other
routers act as backups in the case of the master one failing.
