Hi Andrew,
Thank you for your reply, this is mock lab 4 I was doing.
I'm always a little unsure as to which point I should ask the proctor a
question through fear of looking stupid and giving the proctors the feeling
that "he wont be here for too long", but I'm starting to get more confident
now especially with things like this, I suppose it's all down to how I word my
question to them aswell i.e. "You've specified on the outline that I need to
have full reachability to outside networks but there is no task to fulfill
this requirement, would you be happy for me to redistribute into my IGP?"
Thanks again
Howard

Subject: Re: LAB Reachability
Ask the proctor. For the IE labs I often have trouble determine where
reachability is needed as sometimes they specify it is not needed to none BGP
routers and other times the redistribution is simply not configured. Normally
in their solution guide they do not have you redistribute the BGP routes into
IGP unless of course a specific task requires it, which often contradicts the
general rules for the lab. As with most ask the proctor moments I reread the
question and try to determine what they are trying to test. For the workbook
it is fine and I think not having them tell you exactly what to configure all
the time in respect to the backbones keeps you sharp, if I ran into some real
ambiguity on a mocklab I would probably be upset. What mocklab was this? I
have taken 1,2,3,5 without any huge issues although on I think mocklab 3 I did
a real simple BGP to IGP redistribution in a similar situation to yours when
it was not needed.

Hi,
Please can anybody offer their advice as to what you would do in this
particular lab situation?
On the front page of the practice lab it clearly says "Upon completion, all
devices should have full IP reachability to all networks in the routing
domain, including any networks generated by the backbone routers"
However when going through the lab document and carrying out the various
tasks
I'd been given I came to a point where I had to setup bgp peering sessions
between two of my three internal routers that were running bgp and two of
the
backbone routers, after doing this I'd received a few networks from the
backbone on each router so no problem there, but at that point the lab went
on
to multicast.
So I'm confused about, if I'm told every router on my internal network
should
be able to see eachother plus the networks generated by the backbone routers
but then due to the lab tasks given only two of my routers can actually see
any networks from the backbone and I'm not told to do anything further, what
would anybody recommend doing in this situation if faced in the lab exam?
As per the lab guidelines I wasn't allowed to create any static routes, do
any
policy routing, change or add IP Addresses so I redistributed between bgp
and
the igp running on my internal routers, would I be marked down or lose
points
for adding in redistribution that I'm not told to do?
Any help or advice you can give for this situation would be great, thank you
Also if anyone from IE is reading this post and happens to be grading my
lab...I'm so sorry. I reached the decision to do redistribution within the
last minute of the lab and after setting it up quickly between bgp and ospf
on
one of the routers then quickly copying and pasting the commands to the
second
router...time runs out...damn!this router is running RIP not OSPF!....you'll
see what I mean when you get to R6...:o)
I'm not intentionally stupid, the medication wears off quickly thats all :o)
