  • A Use an extended access list instead of a standard access list.
  • B Change sequence 10 in the route-map command from permit to deny.
  • C Use a prefix list instead of an access list in the route map.
  • D Add this statement to the route map: route-map RM-OSPF-DL deny 20.
Explanation

A route map used by an OSPF distribute list permits or denies routes according to the matching route-map clause. Access list 1 matches 192.168.2.2, and sequence 10 currently permits that match. Changing sequence 10 to deny filters the matched route from the routing table.
