Note: You can only configure VRRP on interfaces with unique VLAN IDs.
Note: Routing domains with the same VLAN ID are not displayed in the table indicated.
Figure 422 NETWORKING > VRRP > VRRP Setup: IP Interface
The following table describes the labels in this screen.
72.3.2 VRRP Parameters
This section describes the VRRP parameters.
72.3.2.1 Advertisement Interval
The master router sends out Hello messages to let the other backup routers know that it is still up and
running. The time interval between sending the Hello messages is the advertisement interval. By default,
a Hello message is sent out every second.
If the backup routers do not receive a Hello message from the master router after this interval expires, it
is assumed that the master router is down. Then the backup router with the highest priority becomes the
master router.
Note: All routers participating in the virtual router must use the same advertisement interval.
