DGS-3312SR Stackable Gigabit Layer 3 Switch

VRRP Interface Settings
The following window will allow the user to view the parameters for the VRRP function on the Switch. This window can
also be 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.
Figure 5- 47. VRRP Interface Settings window
The following parameters may be set to configure an existing or new VRRP interface.
Parameter Description
Interface Name
Enter the name of a previously configured IP interface to create a VRRP entry for. This
IP interface must be assigned to a VLAN on the Switch.
VRID (1-255)
Enter a value between
1
and
255
to uniquely identify this VRRP group on the Switch. All
routers participating in this group must be assigned the same
VRID
value. This value
MUST be different from other VRRP groups set on the Switch.
IP Address
Enter the virtual IP address that will be assigned to the VRRP entry. This IP address is
also the default gateway that will be statically assigned to end hosts and must be set for
all routers that participate in this group.
Admin. State
Used to enable (
Up
) and disable (
Down
) the VRRP IP interface on the Switch.
Priority (1-255)
Enter a value between
1
and
255
to indicate the router priority. The VRRP Priority value
may determine if a higher priority VRRP router overrides a lower priority VRRP 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. VRRP routers that are assigned the same priority value will elect the
highest physical IP address as the Master router. The default value is
100
.
Advertisement
Interval (1-255)
Enter a time interval value, in seconds, for sending VRRP message packets. This value
must be consistent with all routers participating within the same VRRP group and is
used to troubleshoot incorrectly configured routers. The default is
1
second.
Preempt Mode
This entry will determine the behavior of backup routers within the VRRP group by
controlling whether a higher priority backup router will preempt a lower priority Master
router. A
True
entry, along with having the backup router’s priority set higher than the
masters priority, will set the backup router as the Master router. A
False
entry will
disable the backup router from becoming the Master router. This setting must be
consistent with all routers participating within the same VRRP group. The default setting
is
True
.
