This command suppresses the advertisement of all the IPv4 prefixes except for prefixes that are associated with secondary IPv4 addresses, loopbacks, and passive interfaces from the OSPFv2 router advertisements.
To suppress a loopback or passive interface, use the ip ospf prefix-suppression command in interface configuration mode. Prefixes associated with secondary IPv4 addresses can never be suppressed.
