[j-nsp] JNCIP question: what's the area 49.0003 in ISIS case study?

[Harry Reynolds]

Yes. Area 0003 is for any new router that will be L2 only. In the book topo, all the L2 routers happen to need a L1 adjacency, hence none actually have the l2 area address.

( for Harry's JNCIP book)

hey all,

I've been puzzled on this for a while. r3/r4 is in area 49.0002 and r5 in area 49.0001, so what's area 49.0003 for? it appears in the criteria as:

"The subnet between r3 and T1 must appear in area 49.0003 as an internal route. Ensure that no adjacencies can be established on this subnet."

what does that mean? seems the sample config desn't reflect 49.0003.
am I missing something?
