Parameter Description
Interface Name
The name of a previously created IP interface for which to configure the VRRP
authentication.
Authentication Type
Specifies the type of authentication used. The Authentication Type must be
consistent with all routers participating within the VRRP group. The choices are:
• None - Selecting this parameter indicates that VRRP protocol exchanges
will not be authenticated.
• Simple - Selecting this parameter will require the user to set a simple
password in the Auth. Data field for comparing VRRP message packets
received by a router. If the two passwords are not exactly the same, the
packet will be dropped.
• IP - Selecting this parameter will require the user to set a MD5 message
digest for authentication in comparing VRRP messages received by the
router. If the two values are inconsistent, the packet will be dropped.
Authentication Data
This field is only valid if the user selects Simple or IP in the Authentication Type
field.
• Simple will require the user to enter an alphanumeric string of no more than
eight characters to identify VRRP packets received by a router.
• IP will require the user to enter a MD5 message digest for authentication in
comparing VRRP messages received by the
router.
This entry must be consistent with all routers participating in the same IP interface.
