Virtual Router Redundancy Protocol (VRRP) | 955
Configure the VRRP Group’s priority with the following command in the VRRP mode:
Figure 50-7. Command Example: priority in Interface VRRP mode

Configure VRRP Authentication
Simple authentication of VRRP packets ensures that only trusted routers participate in VRRP processes.
When authentication is enabled, FTOS includes the password in its VRRP transmission, and the receiving
router uses that password to verify the transmission.
Task Command Syntax Command Mode
Configure the priority for the VRRP
group.
INTERFACE -VRID
priority priority
Range: 1-255
Default: 100
Note: All virtual routers in the VRRP group must be configured the same: authentication must be enabled
with the same password or authentication is disabled.
