Chapter 3 Configuring Additional Router Features
Configuration Limiting
Maximum Interfaces for Each OSPF Instance
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
