Set group priority
Set a virtual router priority to 255 to ensure that router is the owner virtual router for the VRRP group. The router which has
the highest primary IP address of the interface becomes the master. The default priority for a virtual router is 100. If the master
router fails, VRRP begins the election process to choose a new master router based on the next-highest priority.
1. Create a virtual router for the interface with the VRRP identifier in INTERFACE mode (1 to 255).
vrrp-group vrrp-id
2. Configure the priority number for the VRRP group in INTERFACE-VRRP mode (1 to 255, default 100).

Authentication
Simple authentication of VRRP packets ensures that only trusted routers participate in VRRP processes. When you enable
authentication, OS10 includes the password in its VRRP transmission. The receiving router uses that password to verify the
transmission.
You must configure all virtual routers in the VRRP group with the same password. You must enable authentication with the same
password or authentication is disabled. Authentication for VRRPv3 is not supported.
