IP routing advanced configuration 143
Configuration Guide
Primary IP Address Type the primary IP address for the virtual router.
When the virtual router transitions from backup state to master state and
in case more than one IP address exists for a given interface index, the
primary IP address specifies the real IP address of the master router (the
IP address that is listed as the source in the VRRP advertisement last
received). If the primary IP address is set to 0.0.0.0, the IP address that is
numerically lowest is selected.
Priority Type the priority for the Virtual Router master election process. The value
ranges from 0 to 255, although the range of values you may enter is 1 to
254.
Higher values indicate higher priority.
A priority value of 0 is set by the master router to indicate that this router
has ceased to participate in VRRP. A backup virtual router must transition
to become a new master.
A priority value of 255 is used for the router that owns the associated IP
addresses.
The default value is 100.
Authentication Type Select the Authentication type used for VRRP protocol exchanges
between virtual routers.
If you select No Authentication, the VRRP Protocol exchange values are
not authenticated.
If you select Simple Text Password, the VRRP Protocol exchanges are
authenticated by a clear text password.
The default value is No Authentication.
Authentication Key Type the authentication key for the virtual router, if the Authentication
Type is Simple Text Password.
Advertisement Interval
(Seconds) Type the time interval for sending the advertisement packets.
Only the master router sends VRRP advertisements.
The value ranges from 1 to 255.
The default value is 1.
Pre-emption Specifies the preemption status.
Select Enable to enable preemption mode.
Select Disable to disable preemption mode.
The default value is Enable.
Oper State Displays the current state of the virtual router. The current state may be
one of the following:
• Initialize - the virtual router is waiting for a startup event.
• Backup - the virtual router is monitoring the availability of the master
router.
• Master - the virtual router is forwarding packets with IP addresses that
are associated with the router.
