OSPF Configuration Tasks
Configuring OSPF requires careful coordination among a variety of routing devices:
■
Routers internal to a single area
■
Routers that link multiple areas within a single routing domain; these routers
are called area border routers (ABRs)
■
Routers that link multiple routing domains; these routers are called autonomous
system boundary routers (AS boundary routers)
To minimally configure OSPF, you must:
1.
Enable OSPF.
2.
Configure and aggregate network ranges.
3.
Create the router’s OSPF network interfaces.
4.
Define the OSPF areas attached to the router.
The following sections describe how to perform these tasks.
Starting OSPF
You enable OSPFv2 and OSPFv3 differently. When you enable OSPFv2 on your
router, you can create either a range of OSPFv2 interfaces or a single OSPFv2
interface. When enabling OSPFv3, you create the OSPFv3 interface and assign the
interface to an area.
Enabling OSPFv2
You can create OSPFv2 interfaces in the following ways:
■
You can issue the network area command, which creates OSPF interfaces for
all IP interfaces with IP addresses within the specified range.
■
You can issue the address area command, which creates an OSPF interface in
the specified area that sits on top of the IP interface at the given IP address (or
on the unnumbered interface, if that is specified).
NOTE: Do not enable OSPF on any unidirectional interfaces (such as an MPLS tunnel),
because it can never form an adjacency.
You can delete OSPFv2 interfaces in the following ways:
