Im trying to summarize 3 networks into to 1 advertisement.

Here is a partial network Diagram

R5 ------------------ E0 11.1.1.5/16 \
                            |         \ Area 4 NSSA
                            |         /
                            |        /
R6 ---S1 11.2.1.1/16 \ E0 11.1.1.6/16
               |      \
               |       \
               |        \
R7 -----S4 11.2.1.2/16    \
R7 -----Lo0 11.3.1.1/16    \
R7 -----Lo1 11.4.1.1/16     \ Eigrp 1
                            /
                           /

Now I want to Summarize nets 11.2.0.0/16 through 11.4.0.0/16 on R5

What I have done is the following

R5=20
 router ospf 1
 area 4 nssa
 area 4 default-cost 20=20
 summary-address 11.0.0.0 255.248.0.0
 network 10.10.0.0 0.0.255.255 area 0
 network 11.1.0.0 0.0.255.255 area 4

This seems to work, (other routers in the OSPF process see a route to =
11.0.0.0/13) but Im wondering about the Summary-Address 11.0.0.0 =
255.248.0.0 command. Am I summarizing using the correct prefix? or am I =
summarizing to many networks?

TIA
