Cisco Systems OL-14361-01 manual Maximum Interfaces for Each Ospf Instance Example, 124

Chapter 5 Configuring Additional Router Features

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

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
