Hi 
Please clarify me regarding the Removal of excess paths.
As per Pg. 15, (Sec. 7.2.7) of ISO 10589 - ver 1992,
~~~~
"When there are more than maximumPathSplits legal paths to a destination, this set shall be pruned until only maximum-PathSplits remain. The Intermediate system shall discriminate
based upon:
..
circuit ID: where two or more paths are associated with adjacencies of the same type, and same neighbour ID, an adjacency with a lower circuit ID is retained in prefer-ence to an adjacency with a higher circuit ID, where circuit
ID is the value of
· ptPtCircuitID for non-broadcast circuits,
· l1CircuitID for broadcast circuits when running the
Level 1 Decision Process, and
· l2CircuitID for broadcast circuits when running the
Level 2 Decision Process."
~~~~
here I beleive isisCircPttoPtCircID (isisCircEntry 22) (Circuit Table MIB Object) is to be used as the 
ptPtCircuitID for non-broadcast circuits to do the removal of excess paths, ..., 
(Incidentally this isisCircPttoPtCircID is filled after the negotiation of the Hello PDUs, hope i'm right here!!!)

BUT,
which MIB object is to be used for the l1CircuitID & l2CircuitID for the Broadcast Circuits.

correct me if i'm wrong.

P.S.:- This mail, when sent to the isis-wg is bouncing back as "host not found" !!!

Thanks
