Yes, i agree but the point is to filter the redistribution. For example i want to redistribute connected routes but not all. Than the LSD is the same on all machines in that area, and i just limited the redistribution of ,for example, private ip addresses: router ospf 10 redistribute connected route...

Hi,

can i somehow filter incoming and outgoing OSPF routes ? I did not found a prefix-list option in OSPF routing.
Thank you !
