Hi David

This is undocumented command by cisco .

This command shows you the lsas which have been deleted from
consideration.  as i don't have ospf running, i can't ascertain whether
this is lsas which were taken out of consideration by the SPF algorithm
or by other means.

ctalkb#sh ip ospf delet
  AS System  N

    Area BACKBONE(0)

    ROUTER and NETWORK LSDB delete list

      Dest:, Type: 0, Metric: 1, ADV RTR:
        gateway, interface Loopback0

    SUMMARY NET and ASBR LSDB delete list

    TYPE-7 EXTERNAL LSDB delete list

    EXTERNAL LSDB delete list  

Please refer the below link for Cisco undocumented command & there detail
