OSPF Area Aggregation Settings

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 Layer 3
Features > OSPF > 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.

xStack DGS-3600 Series Layer 3 Gigabit Ethernet Managed Switch
Description
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.
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.
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.
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.
If using authorization for OSPF routers, select the type being used. MD5 key authorization
must be set up in the MD5 Key Settings menu.
Enter a case-sensitive password for simple authorization or enter the MD5 key you set in the
MD5 Key settings menu.
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.
The number of seconds between link state advertisement retransmissions for adjacencies
belonging to this virtual link. This field is fixed at 5 seconds.
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, the
Authorization Type and Password or Key used must likewise be identical.
