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.
