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.
The master router regularly sends VRRP advertisement packets to the backup routers. If
the backup routers do not receive the VRRP advertisement packets for a time that is three
times the selected period, they assume that the master router has fallen and commence a
process for selecting a new master.
