Configuring the Open Shortest Path First Protocol (Version 2)
Figure 330: Showing OSPF Process Identifiers
To implement dynamic OSPF routing, first assign VLAN groups to each IP
subnet to which this router will be attached (as described in the preceding
section), then use the Routing Protocol > OSPF > System (Configure) page
to assign an Router ID to this device, and set the other basic protocol
parameters.

These parameters are displayed in the web interface:

General Information
RFC1583 Compatible – If one or more routers in a routing domain
◆
are using early Version 2 of OSPF, this router should use RFC 1583
(early OSPFv2) 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)
When RFC 1583 compatibility is enabled, only cost is used when
choosing among multiple AS-external LSAs advertising the same
destination. When disabled, preference is based on type of path, using
cost only to break ties (see RFC 2328).
If there any OSPF routers in an area exchanging summary information
(specifically, ABRs) which have not been upgraded to OSPFv2
(RFC 2328), RFC 1583 should be used on the newly upgraded OSPFv2
routers to ensure compatibility with routers still running older OSPFv2
code.
OSPF Router ID – Assigns a unique router ID for this device within the
◆
autonomous system for the current OSPF process.
The router ID must be unique for every router in the autonomous
system. Also, note that the router ID can be set to 0.0.0.0 or
255.255.255.255.
