Hiyah,
I'm not a great fan of asking Proctor questions, From experience,
Proctors don't offer me what I never knew in the Lab. I've heard someone
said a Proctor in far east told a candidate that the candidate has got a
better knowledge of English than himself.
Now to the point of the question: When the question says advertise a lo0
into area x, I wouldn't waste much time as one of the ways to do this
(Like we all know) is to activate OSPF on that lo0 {Although this comes
into OSPF as /32 by default with an ospf network type of loopback ...
Again like we all know)
Another way to do this will be to redistribute connected into OSPF with
a route-map matching only this lo0 (yet again, like we all know)
I know there are ways to go about this even if we're restricted not to
use the network/redistribution method. One of which will be the
interface command "ip ospf <pid> area <areaid> ... Although you're
almost forbidden to use this command if there is no restriction. I'm
also sure there are other ways to advertise a network into ospf.
Bottom Line:
ADVERTISE: From my own point of view, the word advertise simply means,
let other non-directly connected OSPF routers see an OSPF Route in their
routing table to get to the Lo0 of the Specific Router in question. (So,
you're advertising your lo0 to them!!!!)
This could either be /32(default) or /24 (if required)
With regards to Asking Proctor Questions in the Lab, this is my own
opinion and I seriously believe there are so much nice proctors out
there, only that they are not allowed to give you a solution to
questions, some give clues and narrow down your options when questions
don't specify, but you know what? I'm yet to meet such a Proctor!!!
Many Thanks
Yemi Salau

Subject: Meaning of advertise
Hi group,
This may be a dumb question but I will ask anyway. :)
If a requirement/task/question uses the term "advertise", as in
advertise the loopback into area x, for example. Does "advertise" in
this case mean use any means necessary to get the address/prefix into
the protocol (network statement, redistribute, etc)? Obviously if there
are restrictions in the lab, it limits the scope. I was just wondering
if there is a right or wrong interpretation of this term when there are
no restrictions. I interpret it as bring the prefix into the routing
protocol. Maybe this is a proctor question if it comes up?
Jason
