Command:

debug ip ospf monitor


Mode:

Router#


Syntax:

debug ip ospf monitor

no debug ip ospf monitor

 

Syntax Description:

This command has no arguments or keywords.

 

Command Description:

To determine if the link is brought up due to a change in network topology, use the debug ip ospf monitor command. The no form of this command disables debugging output.


Example:

The output below shows there was a change in the router LSA with the router ID of 192.168.246.41, which causes the database to be resynchronized. If the network is stable, then this debug output shows nothing.

To reduce the affect of link flaps on the demand circuit, configure the area that contains the demand circuit as totally stub. If this isn't doable, and there is a constant link flap within the network, demand circuit might not be a good choice for you.

The example shows which LSA is changing, as seen below:

Router#debug ip ospf monitor
OSPF: Schedule SPF in area 0.0.0.0
        Change in LS ID 192.168.246.41, LSA type R,
OSPF: schedule SPF: spf_time 1620348064ms wait_interval 10s


Misconceptions:

None.
