Requirement:

How is OSPF flooding debugging enabled?



Solution:

In the following example the IP address is removed and added from the Loopback 0 interfaces. The first debugging message is the flush message and the second message is the add message.



Configuration:

Rack2sw1# debug destination session
Rack2sw1# debug ip ospf flood
Rack2sw1# show debug

 Debug Logging

  Source IP Selection: Outgoing Interface
  Origin identifier: Outgoing Interface IP
  Destination:
   Session

  Time-stamp: System-Uptime

  Enabled debug types:
   ip ospf flood
 



Verification

Rack2sw2(config)# no interface loopback 0
Rack2sw2(config)# interface loopback 0 ip address 2.2.2.2
