Not to belabor something you may find obvious... But if you redistribute a
route, it is not part of an area. :)
So I'd look to the network statement, or the interface-based command in
12.4.
Don't spend too much time looking for random hidden issues. Experience will
let you know all the hidden things, which are typically related to
inter-working of scenario questions, not any one single thing like
advertising a route!

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

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
