Hello Cisconuts,
I am sorry that you feel that this book is useless, I have spoken with
many people that have done the labs including myself and they actually
have very good regards for the book including those that work for Cisco.
From what I gather I am not sure if you are taking the time to actually
do the lab or are just reading it looking for mistakes. Some of the
questions that you ask are explained in the solution details. I think
you are focusing to much on the erros and not enough on the positives.
Again this book is written by a CCIE proctor, I think it is a wonderful
resource. I am happy to answer your questions as I have done all the
labs myself and got all the labs to successfully work as per the answer
key and their verification. I also have a solution forum that you can
discuss. Here are the responses to your questions as far:
a. why is the loopback
intf. configured as point-to-point? Nowhere is there a requirement to
see
them as a /24 anywhere?? Have they asked us ??
Answer:
how is configuring a ip ospf network point-to-point a mistake? It
basically instead of the route appearing as a host route, it appears as
a network /24 in this case. It can prevent issues further on from
happening. Again I had to go to expensive bootcamp to learn this lesson.
b. why does the serial
intf. have ip ospf network point-to-point and point-to-multipoint
configured (ex. on R2) Nowhere have they asked us to do that? I feel
they
should be left as default network type and get that to work.(using the
neighbor cmd. and ip os prio 255 on the hub)
as 1.1, as far as the lab goes it says in the beginning that you are
permitted to use subinterfaces on R2 interface s0/1.
Answer:
It does not say you have to use subinterface on R2, it just says you are
permitted. It only says that DO Not configure subinterfaces on any other
routers. The serial interface of R2 has a point-to-point and a
multipoint, if you look at the topology, there is a point-to-point
network from r2 and r3, R2 has a multipoint to R5, R1 and R4. So to me
this makes logically sense to have a point-to-multipoint. And this is
with 2 interfaces, there is not a ip ospf network point-to-point and ip
ospf network point-to-multipoint on the same interface. Again these are
2 separate serial interfaces and if you look at the diagram it makes
sense.
c. Why is the Bri0/0 on R3
configured as no peer neighbor-route?
What other mistakes do you see on Section 2.1?
Answer:
The no peer neighbor route is configured because as you know it will
prevent a host route from appearing in the routing table and causing
issues. So I am not sure how you see it as an error in the book.
Why is only virtual-link configured b/w R3 and R2? Why not b/w R3 and
R5? If the FR b/w R3 and R2 goes down, how will vlan33 on R3 get to area
0 on R5??
Answer:
I am pretty sure this question was answered before basically the lab did
not ask for redundancy. So that is why you don't see 2 virtual-links.
Section 2.3 asks us to configure Rip only on e0/0 of R4 but the
solution does not have the passive-interface default command and a no
passive-interface e0/0 on R4? If this is not needed on R4 then why in
the
preceding section for Eigrp regarding the same type of question, the
passive-intf. cmd. is used?
Answer:
R4 ethernet interface is network 140.200.0.0/16 the other interfaces
loopback and serial are on 160.10.0.0/16 network. So it is not necessary
to put a passive interface and a no passive on Ethernet 0, just include
that 140.200.10.0 network in the rip process. As far as the eigrp
process, you could use the passive interface default command with the no
pass because there are other interfaces in the 160.10.0.0/24 network.
You could have also just put the interface in the routing process for
example, network 160.10.33.0 0.0.0.255. As long as it doesn't restrict
you from doing so.
If you have further questions please don't hesitate to call me to
discuss. Also if you need rack time I am willing to give out my rack for
FREE!!! And don't forget the forum area, I also encourage you to sign up
as a member.

Subject: Cisco Press R&S Lab workbook - Clarification needed - ???
Hello,Just finished Lab 4 of the Cisco Press R&S Lab Workbook and had
some questions: 1. Section 1.1 asks to configure FR on R2,R4,R5 & R1
and
says that subinterfaces are permitted on R2 only I configured multipoint
on R2 but the solution uses physical intf. Woudl a mp be valid? 2.
Section 2.1 asks to configure loopbacks as part of Ospf. And also other
Ospf tasks and a Virtual link taks requirements. The solution has
multiple mistakes (If I may have spotted them): a. why is the loopback
intf. configured as point-to-point? Nowhere is there a requirement to
see
them as a /24 anywhere?? Have they asked us ?? b. why does the serial
intf. have ip ospf network point-to-point and point-to-multipoint
configured (ex. on R2) Nowhere have they asked us to do that? I feel
they
should be left as default network type and get that to work.(using the
neighbor cmd. and ip os prio 255 on the hub) c. Why is the Bri0/0 on R3
configured as no peer neighbor-route? They have not asked us to do this.
I understand why we would use the command but have they asked us - No !!
d. Why is only virtual-link configured b/w R3 and R2? Why not b/w R3 and
R5? If the FR b/w R3 and R2 goes down, how will vlan33 on R3 get to area
0 on R5?? Section 2.3 asks us to configure Rip only on e0/0 of R4 but
the
solution does not have the passive-interface default command and a no
passive-interface e0/0 on R4? If this is not needed on R4 then why in
the
preceding section for Eigrp regarding the same type of question, the
passive-intf. cmd. is used? These are what I have found upto the IGP
section. I still have to go over the rest of the solutions for Lab 4.
My
only problem and the only reason why I ask these questions is: This book
was written by a Lab Proctor (still a valid proctor, I think)....If he
has this kind of solutions, then with what I have learnt so far is
pretty much useless....I would flunk badly in the Lab. Or is it just an
overisight by the authors?? Please tell me it is. Thank you.Sincerely.
