OSPFv2 is a compatible upgrade to OSPF. It involves enhancements to
protocol message authentication, and the addition of a point-to-
multipoint interface which allows OSPF to run over non-broadcast
networks, as well as support for overlapping area ranges.
•
When using OSPF, organize the network (that is, autonomous system)
into normal, stub, or not-so-stubby areas; configure the ranges of
subnet addresses that can be aggregated by link state advertisements;
and configure virtual links for areas that do not have direct physical
access to the OSFP backbone.
•
To implement OSPF for a large network, first organize the network
into logical areas to limit the number of OSPF routers that actively
exchange Link State Advertisements (LSAs). Then define an OSPF
interface by assigning an IP interface configured on this router to
one of these areas. This OSPF interface will send and receive
OSPF traffic to neighboring OSPF routers.
•
The exchange of OSPF traffic can be further optimized by
specifying an area range that covers a large number of subnetwork
addresses. This is an important technique for limiting the amount of
traffic exchanged between Area Border Routers (ABRs).
•
And finally, specify a virtual link to any OSPF area that is not
physically attached to the OSPF backbone. Virtual links can also be
used to provide a redundant link between contiguous areas to
prevent areas from being partitioned, or to merge backbone areas.

Configuring General Protocol Settings
To implement dynamic OSPF routing, first assign VLAN groups to each IP
subnet to which this router will be attached, then use the OSPF / General
Configuration menu to enable OSPF, assign an Router ID to this device, and set
the other basic protocol parameters.
Command Attributes
General Information
•
OSPF Routing Process – Enables or disables OSPF routing for all IP
interfaces on the router. (Default: Disabled)
•
OSPF Router ID – Assigns a unique router ID for this device within the
autonomous system. (Default: The lowest interface address)
