■
You can issue the no network area command, which deletes all OSPF interfaces
within the specified range.
■
If the OSPF interface was created with the address area command, you can
issue the no address area command to delete the specified interface.
■
You can issue the no ip address command to delete the IP interface associated
with the OSPF interface and also the OSPF interface itself.
NOTE: If an OSPF interface is configured on top of an IP interface and you delete
the IP interface, the corresponding OSPF interface is also deleted. The previously
configured network range, however, is not deleted. You must issue the
no network
area command to delete the range.
Enabling OSPFv3
NOTE: Before you can enable OSPFv3, you must specify an IPv6 license key. For
additional information about configuring an IPv6 license key, see “Configuring an
IPv6 License” on page 134.
OSPFv3 provides IPv6 support in the OSPF protocol. To enable OSPFv3:
1.
Issue the ipv6 router ospf command, and specify a process ID.
2.
Use the router id command to specify a router ID for OSPFv3.
See “Specifying an OSPF Router ID” on page 255.
3.
Issue the ipv6 ospf area command (in interface configuration mode) to create
an OSPFv3 interface under an area ID.
You can delete OSPFv3 interfaces in the following ways:
■
You can issue the no ipv6 router ospf command, which deletes OSPFv3.
■
You can issue the no ipv6 ospf area command to remove the OSPF interface
from a specific area.
Creating a Range of OSPF Interfaces
To create a range of OSPFv2 interfaces:
1.
Create an OSPF routing process.
2.
Create the range of IP addresses associated with the routing process and the
corresponding OSPF interfaces.
3.
Assign an area ID associated with each range of IP addresses.
Each router running OSPFv2 has a database describing a map of the routing domain.
This map needs to be identical in all participating routers.
