DXS-3350SR Gigabit Layer 3 Switch
Configure the following parameters if you are adding or changing an OSPF Virtual Interface:
Parameter
Description
Transit Area ID
Allows the entry of an OSPF Area ID
− previously defined on the Switch − that
allows a remote area to communicate with the backbone (area 0). A Transit Area
cannot be a Stub Area or a Backbone Area.
Neighbor Router
The OSPF router ID for the remote router. This is a 32-bit number in the form of
an IP address (xxx.xxx.xxx.xxx) that uniquely identifies the remote area’s Area
Border Router.
Hello Interval (1-65535)
Specify the interval between the transmission of OSPF Hello packets, in seconds.
Enter a value between 1 and 65535 seconds. The Hello Interval, Dead Interval,
Authorization Type, and Authorization Key should have identical settings for all
routers on the same network.
Dead Interval (1-65535)
Specify the length of time between (receiving) Hello packets from a neighbor router
before the selected area declares that router down. Again, all routers on the
network should use the same setting.
Auth Type
If using authorization for OSPF routers, select the type being used. MD5 key
authorization must be set up in the MD5 Key Settings menu.
Password/Auth. Key ID
Enter a case-sensitive password for simple authorization or enter the MD5 key you
set in the MD5 Key settings menu.
Transmit Delay
The number of seconds required to transmit a link state update over this virtual
link. Transit delay takes into account transmission and propagation delays. This
field is fixed at 1 second.
RetransInterval
The number of seconds between link state advertisement retransmissions for
adjacencies belonging to this virtual link. This field is fixed at 5 seconds.
To return to the OSPF Virtual Interface Settings window, click the
Show All OSPF Virtual Link Entries
link.
NOTE: For OSPF to function properly some settings should be identical on all participating
OSPF devices. These settings include the Hello Interval and Dead Interval. For networks
using authorization for OSPF devices, they Authorization Type and Password or Key used
must likewise be identical.
Area Aggregation Configuration
Area Aggregation allows all of the routing information that may be contained within an area to be aggregated into a
summary LSDB advertisement of just the network address and subnet mask. This allows for a reduction in the volume of
LSDB advertisement traffic as well as a reduction in the memory overhead in the Switch used to maintain routing tables.
Click the OSPF Area Aggregation Settings link to view the current settings. There are no aggregation settings configured
by default, so there will not be any listed the first accessing the menu. To add a new OSPF Area Aggregation setting, click
the Add button. A new menu (pictured below) appears. To change an existing configuration, click on the hyperlinked Area
ID for the set you want to change. The menu to modify an existing configuration is the same as the menu used to add a new
one. To eliminate an existing configuration, click the
in the Delete column for the configuration being removed.
