Editing A VRRP Instance
Figure 139: VRRP Instance
The Name field is purely for informational purposes.
The Interface field configures the interface that VRRP packets are sent upon.
The Virtual Router ID field determines the VRID number. Ensure that all routers
supplying the same VRIP have the same VRID. The value of the VRID varies from 1
to 255.
The Advert Interval field configures the time between VRRP advertisements.
Ensure that all routers supplying the same VRID have the same interval.
Note: VRRP will not work properly if the advertisement interval is different in the
master and backup routers.
The Gratuitous ARP Delay field controls the number of seconds after the router
changes between master and backup state that a second set of gratuitous ARPs are
sent. This mechanism offers a second chance to teach the switching fabric and hosts
of the new provider of a gateway address.
The Extra Interface To Monitor field causes VRRP to release control of the VRIP if
this interface stops running. This prevents the situation where a host forwards
information to a gateway router that itself has no way to forward the traffic.
The Gateway address/mask and Add another Gateway fields configure the VRIP
gateway addresses associated with this VRID. Both an IP address and appropriate
subnet mask must be provided for each gateway.
The Save button saves the virtual instance.
The Delete button deletes the virtual instance. After you save or delete an instance
you must restart the daemon to action your change.
