The 2800 series running 12.4 mainline code does not support the "loose"
parameter on the Proctorlabs common pods. However, during all of the
rearranging/upgrading of gear and addition of equipment pods there, there
will be the creation of a "7200-only" rack, which will be running 12.x
S-train code. That's where the 'loose' parameter exists now anyway.
So after the equipment is moved, then you'll have access to all of those
exciting things brought to you by the S-train code listed on Cisco's web
site as well as some concentrated ATM labs and other fun hardware changes to
come in the future. :)
On the flip side, "loose" is the easier of the TE methods for
semi-constrained paths, so if you know how to do TE with strict path, then
loose shouldn't be a problem for you other than remembering that the
parameter is there.
Your fast reroute is simple specifying a backup path. Almost everything in
the Cisco TE world starts with "mpls traffic-eng" so your "?" based lookups
should be quite simple. Again, an S-Train command set at the moment, but an
important one anyway. You apparantly already know the commands though! :)
When it comes to ERO's, doing traffic engineering really is not a lot of
mental work. You are essentially statically making decisions at different
points, and you just need to program those things in. So once you are aware
of commands (like loose, or backup paths) then the commands are definitely
the simple part. There isn't much magic beyond that.
So you've already pointed out those things, and that makes you well aware of
them and definitely prepared for them. The show commands you'll see in
implementation really aren't any different than what you'd see otherwise.
(except you'll see the backup path listed, and whether it's active or not)
If I were you, I'd look at realease notes for the various 12.x S-train
releases to pick up on other small commands that may be of interest, and
document them by hand first. Then work on access to equipment and test them
out. Your knowledge/recall of these commands then will be increased by the
repetition.
Like any track, practice certainly helps the repetition. And sorry to say
that part isn't available yet at this point in time, but very soon. We are
working on fixing the typos/errors, updating the labs, coming out with a
proctor guide, and changing/upgrading hardware all at the same time. So
busy things are happening, but good things coming along!

Subject: CCIE Service Provider and IPExpert Workbook.
Hi,
Im studing for the CCIE SP Lab exam. I bought the IPExpert WB3 for Service
provider.
I noticed that the book has a lot of typos/ erros and the configuration
files (initall) and even worse the somtiimes Final configutations are
missing. IPExpert promised me that they will fix, but it will take some
weeks. I also noticed that the book does not cover "MPLS TE fastreroute and
Loose ERO "next address LOOSE x.x.x.x". These are valid test topics at the
current CCIE SP lab exam.
Does anyone has some practice material which I can use? Does anyone know a
Service provider rental service which does support TE fast reroute and Loose
ero's (proctorlabs does currently not, or I'm missing something).
Thanks and regards,
J.
