I have also been tooling around with the same thoughts.
R4
The only thought I have to R4 is that the 162.1.0.024 is to include the
162.1.45.0/24 network which I would have already taken care of in
Section 4.6, I question this below.
The 150.1.0.0/20 is odd as 150.1.4.4 is included in the OSPF area 0 and
150.1.5.5 is via R5 OSPF area 0 and R4 via static if R5's frame link is
down. ??
R3
Again not sure why as R3 is originating a default route that is
including everything behind it. R3 then just needs to redistribute OSPF
routes into EIGRP.
Section 4.6. With the static routes on R4 to R5's networks, 162.1.55.5
$ 162.1.5.5 have full reach ability but not 162.1.45.5, which can not be
reached by routers other than R4.
My thoughts that were to fulfill the questions 45.5 has to be reachable
also and would need to be redistributed to meet 4.6 goals. Solution in
4.6, Redistributed connected with route-map to include only
162.1.45.0/24???
I know there are a lot of different ways to handle different scenarios
but questions is which one is the best solution. I would have thought
the completing 4.6 to include 162.1.45.0/24 would have best answered
that section (R5 full connectivity with Frame link down) and not have
been needed to be re-addressed in section 4.8 by the summary address.
My thoughts,
Curt

Subject: Redistribution IEWB Lab5 Q4.8
Hi everybody,
I have a question about the Internetwork Expert Workbook
Lab 5, Question 4.8 Redistribution
I don't understand why the following code lines are in the answer:
R4
Interface e0/0
Ip summary-address rip 162.1.0.0 255.255.0.0
Ip summary-address rip 150.1.0.0 255.255.240.0
My opinion: There is connectivity even if those lines are not included
R3
Router ospf 1
Redistribute eigrp 200 subnets route-map eigrp_to_ospf
My opinion: This protocol redistribution is not necessary due there is a
default line included that allows to reach eigrp and rip from the ospf
network.
Thanks, please advice because it has taking me a lot of time to discover
the reason. :-)
