OSPFv2 is the IPv4 implementation of the Open Shortest Path First protocol. (OSPFv3 is the IPv6 implementation
of this protocol.) Beginning with software version K.15.01, the switches can be configured to run OSPFv2 either
alone or simultaneously with OSPFv3. (OSPFv2 and OSPFv3 run as independent protocols on the switch and do
not have any interaction when run simultaneously.)
For overview information on OSPF, see
on page 247.
Configuring OSPF on the routing switch
Enabling IP routing
Syntax:
[no] ip routing
Executed at the global configuration level to enable IP routing on the routing switch.
Default: Disabled
The
no
form of the command disables IP routing. (Global OSPF and RIP routing must be disabled before you
disable IP routing.)
Example:
switch(config)# ip routing
Enabling global OSPF routing
Syntax:
[no] router ospf [enable | disable]
Executed at the global configuration level to enable OSPF on the routing switch and to enter the OSPF router
context. This enables you to proceed with assigning OSPF areas, including area border router (ABR) and
autonomous system boundary router (ASBR) configuration, and to modify OSPF global parameter settings as
needed.
The
enable
form of the command enables OSPF routing, and the
disable
form of the command disables
OSPF routing.
Global IP routing must be enabled before executing this command.
Default: Disabled
The
no
form of the command deletes all protocol specific information from the global context and interface
context. All protocol parameters are set to default values.
NOTE:
If you disable OSPF, the switch retains all the configuration information for the disabled protocol in
flash memory. If you subsequently restart OSPF, the existing configuration will be applied. After
restarting OSPF, the exiting configuration will be applied and the protocol will be in the disabled state.
