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.

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.
