Excluding a network from OSPF

Unanswered Question
Sep 14th, 2007

How do I exclude a network from OSPF? I have two Point-to-Point T-1s configured with MLPPP. One of the T-1s keeps bouncing and want to take it our of the MLPPP bundle and not have any production traffic go over the link so I can test it with the carrier.

Thanks - Gabriel

I have this problem too.

The IP address is on the multilink interface and there are no IP addresses on the individual T1 interfaces. If you take 1 T1 out of the bundle you would assign an IP address to that interface so you could test. The easy thing is to assign an IP address to the T1 interface that does not match any network statement in your OSPF. If that is a problem then you can just add to your OSPF configuration passive-interface serial . This will prevent any OSPF updates from going over the interface.

Not matching the network statement is the optimum solution.
