On another area, you could aggregate into a /23, and then you could always use an area filter-list to control where you did or did not want to show up.

R2 <--> R5 <--> R6 in OSPF area 0 in which, R2 has route 2.2.0.2/24 and R6 has route 2.2.1.6/24 R5 <--> R4 in OSPF area 45 Can I config R5 such that R4 get the route 2.2.0.0/23 instead of two 2.2.0.0/24, 2.2.1.0/24? I know that I can config ABR by area xx <summarized-prefix> but what if the area is 0, will it make any difference? Thanks a lot.
