Re: Difference IS-IS Area/Level

They cannot be compared - at least not directly. Level-2 can be
compared to OSPF backbone (0.0.0.0) area, but without the affixed area
identifier. Level-1 areas, again very generally, are comparable to
OSPF's totally stubby NSSA areas.

To get some more fun details about OSPF vs. IS-IS, I highly recommend
you listen to the Packet Pushers Podcast on the subject of OSPF and
IS-IS differences. Greg Ferro hosted Ivan Pepelnjak of NIL, Petr
Lapukhov of Microsoft and me for loads of fun discussing these two
protocols. Here's the link:
