i am redistributing connected subnets into OSPF process with following command.

redistribute connected subnets.

All the routes / connected subnets are successfully distributing into OSPF, but there is a connected network on the device which i dont want to be ditributed into OSPF.

How can i exclude some static router from redistributing into OSPF ??

You need to use a route-map.


Example:


connected route 192.168.1.0/24 and 192.168.2.0/24 blocked from redistribution while allowing 192.168.3.0/24 and 192.168.4.0/24



ip access-list standard CONNECTED->OSPF

permit 192.168.3.0 0.0.0.255

permit 192.168.4.0 0.0.0.255



route-map CONNECTED->OSPF

match ip address CONNECTED->OSPF


router ospf 1

redistribute connected subnets route-map CONNECTED->OSPF

Curious why you're redistributing connected subnets vs. making them OSPF interfaces.


Redistribution makes them externals. If you're concerned about peering, you can make interfaces OSPF passive.
