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 identier in INTERFACE mode (1 to 255).
vrrp-group vrrp-id
2 Congure 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 congure 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.

2 Congure a simple text password in INTERFACE-VRRP mode.

• simple—text text — Enter the keyword and a simple text password.
• auth-text — (Optional) Enter a character string up to eight characters long as a password.
