Command Usage
• All routers in the same VRRP group must be configured with the same
authentication key.
• When a VRRP packet is received from another router in the group, its
authentication key is compared to the string configured on this router. If the
keys match, the message is accepted. Otherwise, the packet is discarded.
• Plain text authentication does not provide any real security. It is supported
only to prevent a misconfigured router from participating in VRRP.
Example
vrrp priority
This command sets the priority of this router in a VRRP group. Use the
no
form to
restore the default setting.
