CCIE H3 Section 2.2

question mention that
All OSPF devices must exclude the IP prefixes of connected networks when advertising their type 1 router LSA, except for prefixes associated with loopbacks or passive interfaces.

So i think that output of "sh ip route os" will have /32 for loopback interface and /24 for vlan 2000 and vlan 2001 in case of passive interface enable

is it right ?

You also need "ip ospf prefix-suppression" command under the interface vlan in order to see the output which is requested.

yes thats right by adding one command ip ospf prefix-suppression and passive interface for valn 2000 and 2001 the output will be achived.
