00.00.5E.00.01.VRID as a response to the stations ARP requests.

•

In the meantime, the redundant router will use a VRRP polling protocol to 
check the Main router integrity at one second intervals (default). Otherwise, it is 
idle

•

If the Main router fails, the redundant router that does not receive a response 
from four consecutive polling requests (default) will take over and start to 
advertise the same Virtual MAC for the ARP requests. Therefore the stations 
will not ‘sense’ any change neither in the configured DG nor in the MAC level

•

VRRP has no provisions for routing data base synchronization among the 
redundant routers. You need to perform this manually if needed.

Case #2

•

One router is Main on one IP subnetwork, for example, 20.20.20.0, and 
redundant on another, for example, 30.30.30.0.

•

In this case each IP subnetwork must be in different VRID, for example, 1 & 2 

•

This detailed information is valid for each router in its Main or Redundant roles   

In order to...

Use the following command...

Enable or disable VRRP routing 
globally

Create or delete a virtual router on 
the interface

Assign or remove an IP address to 
the virtual router

Set the virtual router advertisement 
timer value (in seconds) for the 
virtual router ID

Set the virtual router priority value 
used when selecting a master route

Set or disable the virtual router 
simple password authentication for 
the virtual router ID.

Configure or disable the router to 
preempt a lower priority master for 
the virtual router ID
