Hello! Does somebody can tell me if the 2851 supports 12 IS-IS multi-task?
Thanks in advance.

Yes, excuse me. 12 multiareas.

Milady,
The limit for the number of different areas you can have is 29.
Please refer to the following document for more information:

Milady,
This is not a hard limitation but rather a general recommendation for the given platforms. The only hard limitation 29 processes derived from the number of process data blocks (PDBs) available on the box.
12 areas should be no issues depending on how many routes you have in each area of course:
Enter configuration commands, one per line. End with CNTL/Z.
