To configure the VRRP group’s priority, use the following command:
Figure 57-7. priority Command Example
Figure 57-8. 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 the same: enable authentication with the
same password or disable authentication.
