OSPF Commands

User Guidelines
Auto-creation of OSPF areas is supported, so an OSPF area does not have to be defined
before assigning it to an interface. To manually define an OSPF area, use the
router ospf area
command. If the auto-creation option is used, the area definition does not appear in the
running configuration
file.
If a question mark is specified at the end of the
router ospf area
command, the same hint is
displayed twice at the prompt line.
An OSPF routed network must contain an area 0. Only one sub-level of area hierarchy is
allowed, that is all areas other than 0 must connect to area 0 via an ABR (area border router).
An ABR is a router that is connected to two or more OSPF areas.
Small networks usually will only have an area 0. Larger networks will have multiple OSPF
areas to reduce the size of the IP route tables and to reduce the CPU and memory demands
on the routers to a manageable level.
It is not necessary to define an OSPF area globally. OSPF areas may also be defined with the
interface command.
Example
The following example globally defines an OSPF area with the value of 1.
.
router ospf redistribute rip
The router redistribute rip global configuration command enables incorporating IP routes that

redistribution of RIP routes, use the no form of this command.
