•OSPF Router ID – Assigns a unique router ID for this device within the autonomous system. (Default: The lowest interface address)

•Version Number 1 – This router only supports OSPF Version 2.

•Area Border Router 1 – Indicates if this router connect directly to

networks in two or more areas.	backbone	ABR	area,

First algorithm, maintaining a
separate routing database for each area.

• AS Boundary Router 2 –

Allows this router to
exchange routing
information with	AS 1	ASBR	ASBR	AS 2
boundary routers in other
autonomous systems to

which it may be attached.

If a router is enabled as an ASBR, then every other router in the autonomous system can learn about external routes from this device. (Default: Disabled)

•Rfc1583 Compatible – If one or more routers in a routing domain are using OSPF Version 1, this router should use RFC 1583 (OSPFv1) compatibility mode to ensure that all routers are using the same RFC for calculating summary route costs. Enable this field to force the router to calculate summary route costs using RFC 1583. (Default: Disabled)

•Auto Cost (Mbps) 1 – This is the reference bandwidth used to calculate the default cost metric for each interface. To change the cost metric for any interface, use the OSP / Interface Configuration screen.

(Default: 100)
