Title: RE: TE-MIB

Hi Adrian,

It would be more informative if Label value is also added in the ArHopTable of GMPLS-TE-MIB.
And in the bi-directional case, eventhough it may follow the same reverse route,
but, one can not gaurantee the same label values...so, thought should be given
in this respect before finalyzing the extensions.

regards
bhaskara

Incidentally,
In GMPLS, bi-directional tunnels use the same route (in opposite directions) so
the ARHopTable will apply perfectly well.
As Tom says, the GMPLS TE MIB (come to the ccamp meeting and hear about it) will
support the GMPLS extensions.  For bi-directional LSPs the interesting point (in
this respect) will be additional features of the RRO such as label recording for
both directions.
