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.
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.
Configure simple authentication with the following command in the VRRP mode:
Task
Configure a simple text password.
