Time Interval Attribute (default, 1 second)
The time interval value specifies how often VRRP advertisement packets are sent. It
also determines how quickly a backup router can recognize that another VRRP router
is down.
If the backup does not receive a VRRP packet from another VRRP router during the
master down interval, the backup assumes the other router is down. The master down
interval is:
Master _Down_Interval = (3 * Time_Interval) + Skew_Time
Skew_Time = (256 - Priority) / 256
Thus, the default skew time is (256 - 100) / 256, or .609375. The default master down
interval is (3 * 1) + .609375, or 3.609375 seconds.
NOTE:
The time interval must be the same for every router in the Virtual Router, that is, for
every router in the LAN with the same VRID. For example, if a VRRP interface in
routers A, B, and C has the VRID 7, routers A, B, and C must all specify the same
time interval for VRID 7.
The time interval command is:
-> eth vrrp set timeinterval <priority> <vrid> [<port#>]
Password Attribute (no default)
You may specify an optional password of 1 to 8 characters. The password is only
used to authenticate VRRP advertisement packets. It is sent as clear text on the LAN.
If you do not specify a password, no password authentication is done.
NOTE:
The password must be the same for every router in the Virtual Router, that is, for
every router in the LAN with the same VRID. For example, if a VRRP interface in
routers A, B, and C has the VRID 7, routers A, B, and C must all specify the same
password for VRID 7.
The password command is:
-> eth vrrp set password <string> <vrid> [<port#>]
The command to clear the password is:
-> eth vrrp clear password <vrid> [<port#>]
