Title: RE: Decreasing TE-LSP bandwidth, "interoperability issue" (fwd)

Hello !

For re-optimisation I guess. If there is a need to change
the path when bandwidth increase then it's probably usefull
to return to the old path when bandwidth decrease (probably
more optimal).

So changing path probably justify make-before-break and
LSP-ID change.

Did I miss somthing ?

Hi All,

I'd like to re-iterate Der-Hwa's question:

Is there a technical reason that someone can articulate?  Along the
same lines, is make-before-break needed on bandwidth *decrease*?

Thanks,
Kireeti.
