- Priority —(0-255) The interface priority. The value 0 indicates that you cannot define the device
as the designated device on the current network. If more than one device has the same
priority, the router ID is used. The default is 1.
-
Area ID —The OSPF interface area ID.
-
Admin Status Enabled —Enables or disables the OSPF process.
-
Hello Interval —(1-65535) Time (seconds) between Hello packets. All devices attached to a
common network must have the same Hello interval. The default is 10 seconds.
-
Dead Interval —(1-65535 or 2147483647, depending on the device type) Time (seconds) router
Hello packets have not been detected, and the router times out. The value must be a multiple
of the Hello Interval. All routers attached to a common network must have a value specified
for this parameter. The default is 60 seconds.
-
Retransmit Interval —(1-3600) Time (seconds) between link-state advertisement (LSA)
retransmissions for adjacencies belonging to the interface. The value must be greater than the
expected round-trip delay between any two routers on the attached network. The default is
five seconds.
-
Transmit Delay —(1-3600) Estimated time (seconds) required to send a link-state update packet
on the interface. LSAs in the update packet have their age incremented by this amount before
transmission. The default value is one second.
-
Authentication Mode —The interface authentication type, Password or MD5, used to
authenticate OSPF link state messages.
-
Authentication Password / Confirm Authentication Password —The password (eight characters
or less) that authenticates OSPF link state messages.
-
Authentication Key / Authentication Key ID —The MD5 key and its ID that authenticates
OSPF link sate messages. The key field is empty if none exists, however you can select the
authentication as Message Digest-5 (MD5) with a blank key. You can still create key values
with the HTTP cut thru to the device’s web interface. MD5 authentication functions even
while the key value combination is blank
-
Metric Value —(1-65535)—The metric for this type of service on the interface.

VRRP
Virtual Router Redundancy Protocol (VRRP) specifies an elector protocol that dynamically assigns
routing responsibility to one of the VRRP routers on the LAN (the master router). The election
process enables dynamic failover of routing responsibility in case the master router becomes
unavailable. The advantage of VRRP is that it eliminates the single-point-failure phenomenon
inherent to the routing environment by providing a higher availability default path, while
