You need to look at this, as usual, on a case by case basis.
Say, for example, that you cannot statically set the router id under the
OSPF process. However, you have an area disconnected from the backbone.
At this point, you need to setup a virtual link to the backbone. Simple
enough.
When you do this you make a static mapping of the router-id in the
virtual link statement. Recall however you were not allowed to
statically set the router id under the OSPF process.
So what happens if you accidentally add a new loopback interface while
testing some other unrelated part in the lab scenario? Then, you save
it in haste and don't recheck the routing table and reachability.
Yep, you probably just broke the core OSPF process and blew a whole lot
of points.
Just pay attention to where you are being taken. And know how to avoid
the potential problems like this example.
HTH,
Andy

Subject: Router ID
Hi:
I have a question regarding the usage of router id in CCIE lab. My
scenarios are not asking me to set the router id. I have decided to set
it due to some other reasons. Will that be correct? Or is it mandatory
that Cisco should ask explicitly that we need to set the router id.
Besides this, during the router id selection process I choose an id of
my own interest...may be an IP range other than what has been given for
the lab? Will that be alright? Or is the need to be selected from within
the IP range provided in the lab.
Please advice if it does not break NDA.
Thanks,
Noble
