Authentication Data - Alcatel-Lucent 7210 SAS T Configuration Manual

VRRP Overview
Authentication Failure
Any received VRRP advertisement message that fails authentication must be silently
discarded with an invalid authentication counter incremented for the ingress virtual router
instance.

Authentication Data

This feature is different than the VRRP advertisement message field with the same name.
This is any required authentication information that is pertinent to the configured
authentication type. The type of authentication data used for each authentication type is as
follows:
Virtual MAC Address
On 7210 SAS, the MAC address is not configurable. 7210 SAS derives the MAC address to
use from the VRID assigned as defined in the standard.
VRRP Advertisement Message IP Address List Verification
VRRP advertisement messages contain an IP address count field that indicates the number
of IP addresses listed in the sequential IP address fields at the end of the message. The
implementation always logs mismatching events. The decision on where and whether to
forward the generated messages depends on the configuration of the event manager.
To facilitate the sending of mismatch log messages, each virtual router instance keeps the
mismatch state associated with each source IP address in the VRRP master table. Whenever
the state changes, a mismatch log message is generated indicating the source IP address
within the message, the mismatch or match event and the time of the event.
