• OSPF Router ID – Assigns a unique router ID for this device within the
autonomous system. (Default: The lowest interface address)
• Version Number
• Area Border Router
if this router connect directly to
networks in two or more areas.
An area border router runs a
separate copy of the Shortest Path
First algorithm, maintaining a
separate routing database for each area.
• AS Boundary Router
Allows this router to
exchange routing
information with
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)
the default cost metric for each interface. To change the cost metric for
any interface, use the OSP / Interface Configuration screen.
(Default: 100)
