Configuration Limiting
Examples

The following examples illustrate OSPF configuration limits:

•Maximum Interfaces for Each OSPF Instance: Example, page 5-124

•Maximum Routes Redistributed into OSPF: Example, page 5-125

•Number of Parallel Links (max-paths): Example, page 5-125

Maximum Interfaces for Each OSPF Instance: Example

In the following example, the show ospf command is used to display the maximum number of OSPF

interfaces:

RP/0/RP1/CPU0:router# show ospf
Routing Process "ospf 100" with ID 0.0.0.0
Supports only single TOS(TOS0) routes
Supports opaque LSA
It is an area border router
Initial SPF schedule delay 5000 msecs
Minimum hold time between two consecutive SPFs 10000 msecs
Maximum wait time between two consecutive SPFs 10000 msecs
Initial LSA throttle delay 500 msecs
Minimum hold time for LSA throttle 5000 msecs
Maximum wait time for LSA throttle 5000 msecs
Minimum LSA interval 5 secs. Minimum LSA arrival 1 secs
Maximum number of configured interfaces 255
--More--

The following example configures the maximum interface limit on a router:

RP/0/RP1/CPU0:router# configure
RP/0/RP1/CPU0:router(config)# router ospf 100
RP/0/RP1/CPU0:router(config-router)# maximum interfaces 600
RP/0/RP1/CPU0:router(config-router)# end
