Netgear M5300-28G-POE+ (GSM7228PSv1h2) - 12-Port Managed Gigabit Switch Softwarehandbuch

Select Routing > OSPFv3 > Advanced > Common Area Configuration. 

In the Area ID field, enter the OSPF area ID. 

An area ID is a 32-bit integer in dotted-decimal format that uniquely identifies the area to 

which a router interface connects.

Click the Add button.

The area is configured as a common area. 

To delete the common area designation, click the Delete button. 

The area is returned to normal state.

The following table describes the nonconfigurable data that is displayed.



Prepare your computer with a static IP address in the 169.254.100.0 subnet, for 

example, 169.254.100.201.

Connect an Ethernet cable from an Ethernet port on your computer to an Ethernet port on 

the switch.

External Routing

A definition of the router's capabilities for the area, including whether or 

not AS-external-LSAs are flooded into or throughout the area.

SPF Runs

The number of times that the intra-area route table was calculated using 
this area's link state database. This is done using Dijkstra's algorithm.

Area Border Router Count

The total number of area border routers reachable within this area. This 
is initially zero, and is calculated in each SPF pass.

Area LSA Count

The total number of link state advertisements in this area's link state 
database, excluding AS external LSAs. 

Area LSA Checksum

The 32-bit unsigned sum of the link state advertisements' LSA 
checksums contained in this area's link state database. This sum 
excludes external (LSA type 5) link state advertisements. The sum can 
be used to determine if there was a change in a router's link state 
database, and to compare the link state database of two routers. 

Import Summary LSAs 

The summary LSAs are enabled or disabled imported into this area.
