To configure the VRRP group’s priority, use the following command:
Figure 38-7. priority Command Example
Figure 38-8. show vrrp Command Example
Configure VRRP Authentication
Simple authentication of VRRP packets ensures that only trusted routers participate in VRRP processes.
When you enable authentication, 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.
Range: 1 to 255
Default: 100

Note: You must configure all virtual routers in the VRRP group at the same: authentication must be
enabled with the same password or authentication is disabled.
