OSPFv2 Configuration

Introduction
In the "OSPFv2 Configuration" dialog and its sub-dialogs, you can set the OSPF parameters.
OSPFv2 divides the administrated IPv4 network (autonomous system) into various areas.
Within these areas, the link statuses of all routers are exchanged so that each router has a
complete view of the network. This view is maintained in the link state database (LSDB). As
a result, each router can determine all routes within the area itself according to the Dijkstra
algorithm.
There is no uniform view between the areas. For this reason, exchange of routes is restricted
to collective routes that can be determined according to the distant vector algorithm.

Router ID
Here, you set the address of an OSPF interface. The IP address must be unique.
RFC 1583 compatible
You only require this setting if you are still using old OSPFv2 routers that are not compatible
with RFC 2328.
Border Router
Displays the border router status. If the local system is an active member in at least two
areas, this is an area border router.
AS Border Router
Enable this option if this router operates as an AS border router; in other words, delivers to
several protocol worlds (for example, if you operate an additional RIP network).
New LSA received
Number of link state advertisements that were received. Updates and its own LSAs are not
counted.
New LSA configured
Number of different LSAs sent by this local system.
External LSA Maximum
Here, enter the maximum number of external LSAs if you want to limit the external LSDB.
