I am running OSPF on Ten Gig interfaces between Core and Distribution switches.
I want Distribution 1 and Distribution 2 switch (redundant switches) to not be OSPF adjancent.
I wanted to know that if i apply the following commands, will it be ok.
router ospf 10
no passive-interface t2/3
no passive-interface t3/3
T2/3 and T3/3 are Core-1 and Core-2 connecting interfaces. Will applying the command passive-interface default override the previous 2 "no passive-interface commands" or no??
Just wanted to double check this part.
Thanks a lot
Yes this should be fine. You can verify the interface settings once you have added this config -
Edit - apologies i completely misread the question. Rick is correct - the passive-interface default will not override the previous no passive-interface commands. It will just make all other interfaces than t2/3 & t3/3 passive.
you still need to add the network area commands for the interfaces of interest.
2) if the default becomes passive-interface you need no passive-interface for interfaces where you want OSPF hellos to be sent out so the more specific command applies:
no passive for interfaces t2/3 and t3/3 passive for all the other ones whose IP subnets match a network area command
Hope to help
No the passive interface default will not override the the no passive-interface commands. It makes the default behavior to become passive. But any interface configured with no passive-interface will become active.
