RE: How many can administrative groups assigned?

Naidu, Kim,

I think it depends a little bit on the interpretation. In principle the
resource classes can be interpreted either as a bit mask (in which case 32
'base' classes can be defined) or as an integer value (in which case 2^32
values can be used). Even with the bit mask interpretation, derived
resource classes can be built by combining multiple non-mutually exclusive
'base' classes (you could have 32 generic classes called 1, 2, 3 and so on
and then build your resource classes on top of those). The problem lies of
course in the processing of the resource class information. If they are not
used in a simple bitmask, an AND operation is not sufficient to determine
the resource class of a link. Also, if a link would have multiple derived
classes, different TLVs would be needed. It would make sense to expand a
little bit on these issues in the appropriate documents. In my opinion,
this is a general issue with the TE extensions, so it should be explained
there.

Sven.

Kim,

-> If so, how many can administrative groups assigned? 32 or 2^32 ?

  32. A link can me member of multiple admin groups.
