Table 153 Device HA > VRRP Group > Edit (continued)

 

LABEL

DESCRIPTION

 

VRID

Type the virtual router ID number.

 

 

 

 

Description

Type the description of the VRRP group. This field is only for your reference. It may

 

 

be up to sixty printable ASCII characters long.

 

 

 

 

VRRP Interface

Select the interface in this device that is part of the virtual router. You can only

 

 

select interfaces that have static IP addresses.

 

 

 

 

Role

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.

 

 

 

 

Priority

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.)

 

 

 

 

Preempt

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.)

 

 

 

 

Manage IP

This field is available if the selected interface is a Backup interface. Enter the IP

 

 

address of the interface while it is in Stand-Bymode. 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.

 

 

 

 

Manage IP

This field is available if the selected interface is a Backup interface.

 

Subnet Mask

 

 

 

 

 

Authentication

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.

 

 

See Section 13.1.2 on page 236 for more information about authentication

 

 

methods.
