D-Link DI-1750 Reference Manual page 228

♦ Routing interface parameters—Configurable parameters supported include interface output cost,
retransmission interval, interface transmit delay, router priority, router "dead" and hello intervals,
and authentication key.
♦ Virtual links—Virtual links are supported.
♦ Not so stubby area (NSSA)—RFC 1587.
♦ OSPF over demand circuit—RFC 1793.
6.11.2 OSPF Configuration Task List
OSPF typically requires coordination among many internal routers: Area Border Routers (ABRs), which
are routers connected to multiple areas, and Autonomous System Boundary Routers (ASBRs). At a
minimum, OSPF-based routers or access servers can be configured with all default parameter values,
no authentication, and interfaces assigned to areas. If you intend to customize your environment, you
must ensure coordinated configurations of all routers.
To configure OSPF, perform the tasks described in the following sections. The tasks in the first section
are required; the tasks in the remaining sections are optional, but might be required for your application.
♦ Enabling OSPF
♦ Configuring OSPF Interface Parameters
♦ Configuring OSPF over Different Physical Networks
♦ Configuring OSPF Area Parameters
♦ Configuring OSPF NSSA Area
♦ Configuring Route Summarization Between OSPF Areas
♦ Configuring Route Summarization When Redistributing Routes into OSPF
♦ Creating Virtual Links
♦ Generating a Default Route
♦ Configuring Route for Lookup of DNS Names
♦ Forcing the Router ID Choice with a Loopback Interface
♦ Configuring the OSPF Administrative Distances
♦ Configuring Route Calculation Timers
♦ Start the Configuring of On-Demand Link
♦ Monitoring and Maintaining OSPF
In addition, you can specify route redistribution; see the task "Redistribute Routing Information" in the
chapter "Configuring IP Routing Protocol-Independent Features" for information on how to configure
route redistribution.
6.11.3 Enabling OSPF
As with other routing protocols, enabling OSPF requires that you create an OSPF routing process,
specify the range of IP addresses to be associated with the routing process, and assign area IDs to be
associated with that range of IP addresses. To do so, use the following commands beginning in global
configuration directory:
router ospf process-id
network address mask area area-id
Step1：
input routerCommand，prompt:
Command
Model Name
Function
Enables OSPF routing, which places you in router
configuration mode.
Defines an interface on which OSPF runs and define the
area ID for that interface.
