R&S Lab - ISIS?

Unanswered Question
Feb 14th, 2007

It appears that ISIS is not on the CCIE lab exam blueprint. It's interesting that they would test this in the CCNP, but not the CCIE. Does anyone have any idea why? I'm not complaining, as there is plenty to learn on the blueprint as it is!

I have this problem too.

It's still in the CCIE SP, and that makes sense as few enterprises have IS-IS networks (certainly less than ones that have ISDN connections, and that's also not in the R/S anymore).

you're unlikely to use ISIS unless you're working in a large ISP, but in my opinion it makes sense to learn about it to compare with OSPF (pros & cons of both).

CCIE R&S is "enterprise" targeted today, perhaps that 's why they removed it

AFAIK, the focus in CCNP on ISIS isn't that deep, so it shouldn't make any major impact on your studies.

On the flip side, answering 'why', you also have to study MPLS in the CCNP track now. ISIS is used heavily in traffic engineering for MPLS, so that may very well be the segue that someone was looking at when deciding whether to add it to the blueprint or not.
