The key to the issue is the fact that the routes were "redistributed into
OSPF from another IGP".
The area range command only effects inter-area routes.
The summary-address command only effects inter-routing domain routes.
In this example you need both.
If you only use the area range command you will be able to see the routes
redistributed into OSPF and the range summary address.
If you only use the Summary-address command you will be able to see routes
that originated in area 4 but the routes that were redistributed into OSPF
will be summarized.
Hope this helps.

Hi,
A question for those using cciebootcamp labs. I am
practising Task 3 on lab 4.
Question number (8) stated to "Summarize the routes
for R7's E0,E1 and S4 that were redistributed into
OSPF by R6 on R5 so that all of R7's networks appear
as one route to the rest of the OSPF routers except
R6"
Since R5 is a ABR, I used the command "area 4 range
11.0.0.0 255.0.0.0" on R5. But this command did not do
the job as required. I need to use the command
"summary-address 11.0.0.0 255.0.0.0" in order for the
summarized address to be advertised to the rest of the
OSPF routers.
I checked through the answers given, it also have the
command "summary-address 11.0.0.0 255.0.0.0" in R5. Is
that correct ? I thought for ABR, the "area 4 range
11.0.0.0 255.0.0.0" should do the job.
Thanks in advance.
Loh
