Authentication type
Displays the type of authentication used to compare VRRP packets received by a
virtual router. Possible authentication types include:
• No authentication - No authentication has been selected to compare VRRP
packets received by a virtual router.
• Simple Text Password - A Simple password has been selected to compare
VRRP packets received by a virtual router, for authentication.
• IP Authentication Header - An MD5 message digest algorithm has been
selected to compare VRRP packets received by a virtual router, for
authentication.
VRID
Displays the virtual router ID set by the user. This will uniquely identify the VRRP
Interface on the network.
Virtual IP Address
The IP address of the Virtual router configured on the Switch.
Virtual MAC Address
The MAC address of the device that holds the Virtual router.
Virtual Router State
Displays the current status of the virtual router. Possible states include Initialize,
Master and Backup.
Admin. State
Displays the current state of the router. Up will be displayed if the virtual router is
enabled and Down, if the virtual router is disabled.
Priority
Displays the priority of the virtual router. A higher priority will increase the probability
that this router will become the Master router of the group. A lower priority will
increase the probability that this router will become the backup router. The lower the
number, the higher the priority.
Master IP Address
Displays the IP address of the Master router for the VRRP function.
Critical IP Address
Displays the critical IP address of the VRRP function. This address will judge if a
virtual router is qualified to be a master router.
Checking Critical IP
Displays the status of the Critical IP address. May be enabled or disabled.
Advertisement
Interval
Displays the time interval, in seconds, which VRRP messages are sent out to the
network.
Preempt Mode
Displays the mode for determining the behavior of backup routers set on this VRRP
interface. True will denote that this will be the backup router, if the routers priority is
set higher than the master router. False will disable the backup router from becoming
the master router.
Virtual Router Up
Time
Displays the time, in minutes, since the virtual router has been initialized
VRRP Authentication Settings
The VRRP Authentication Settings window is used to set the authentication for each Interface
configured for VRRP. This authentication is used to identify incoming message packets received by a
router. If the authentication is not consistent with incoming packets, they will be discarded. The
Authentication Type must be consistent with all routers participating within the VRRP group.
