• Priority – The priority of this router in a VRRP group. (Range: 1-254;
Default: 100)
- The priority for the VRRP group address owner is automatically set
to 255.
- The priority for backup routers is used to determine which router will
take over as the acting master router if the current master fails.
• Authentication Type – Authentication mode used to verify VRRP
packets received from other routers. (Options: None, Simple Text)
- If simple text authentication is selected, then you must also enter an
authentication string.
- All routers in the same VRRP group must be set to the same
authentication mode, and be configured with the same authentication
string.
- Plain text authentication does not provide any real security. It is
supported only to prevent a misconfigured router from participating
in VRRP.
• Authentication String – Key used to authenticate VRRP packets
received from other routers. (Range: 1-8 alphanumeric characters)
- When a VRRP packet is received from another router in the group, its
authentication string is compared to the string configured on this
router. If the strings match, the message is accepted. Otherwise, the
packet is discarded.
