• Maximum Routes Redistributed into OSPF, page 5-22
• Number of Parallel Links (max-paths), page 5-23
Maximum Interfaces per 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

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
