DESCRIPTION
Type the virtual router ID number.
Type the description of the VRRP group. This field is only for your reference. It may
be up to sixty printable ASCII characters long.
Select the interface in this device that is part of the virtual router. You can only
select interfaces that have static IP addresses.
Select the role that you want the interface plays in the virtual router. Choices are:
Master - This interface is the master interface in the virtual router. The interface
always uses its static IP address, not the management IP address of the VRRP
group.
Note: Do not set this field to Master for two or more routers in the
same virtual router (same VR ID).
Backup - This interface is a backup interface in the virtual router. The interface
may use its static IP address or the management IP address of the VRRP group,
depending on its current role. The current role depends on the other routers in the
virtual router.
This field is available if the selected interface is a Backup interface. Type the
priority of the backup interface. The backup interface with the highest value takes
over the role of the master interface if the master interface becomes unavailable.
The priority must be between 1 and 254. (The master interface has priority 255.)
This field is available if the selected interface is a Backup interface. Select this if
the selected interface should become the master interface if a lower-priority
interface is the master when this one is enabled. (If the role is Master, the interface
preempts by default.)
This field is available if the selected interface is a Backup interface. Enter the IP
address of the interface while it is in Stand-By mode. It is recommended that this
IP address be in the same subnet as the interface. If it is not in the same subnet,
the backup router cannot synchronize with the master via this VRRP interface.
This field is available if the selected interface is a Backup interface.
Select the authentication method used in the virtual router. Every interface in a
virtual router must use the same authentication method and password. Choices
are:
None - this virtual router does not use any authentication method.
Text - this virtual router uses a plain text password for authentication. Type the
password in the field next to the radio button. The password can consist of
alphanumeric characters, the underscore, and some punctuation marks (+-/*= :; .!
@$&%#~ ' \ () ), and it can be up to eight characters long.
IP AH(MD5) - this virtual router uses an encrypted MD5 password for
authentication. Type the password in the field next to the radio button. The
password can consist of alphanumeric characters, the underscore, and some
punctuation marks (+-/*= :; .! @$&%#~ ' \ () ), and it can be up to eight characters
long.
