could you explain the reasoning for having a TE specific TLV in the
auto-mesh document with area and AS-wide flooding scope while the
TE router cap TLV is restricted to an area flooding scope ?
shouldn't be one way or the other i.e. either restrict all TE info
area-local or allow for TE router cap TLV with AS-wide flooding
note: there is nothing in the TE router cap TLV that would impact
scaling more than the TE auto-mesh TLV does
I guess that the reason for allowing both intra and inter-area
flooding scopes for automesh is obvious (we need to have TE LSP mesh
within areas and spanning multiple areas).
So your question is probably why don't we allow the TE router cap TLV
to be flooded across the domain ? As far as I can remember JL already
answered this question ... JL, could you forward your email again ?
In the meantime, I can answer it: the reason is that such TE node
capabilities are used for TE LSP computation which cannot take into
account nodes that do not reside in the node's area.

We have two immediate milestones to address:
Oct 05 First version WG I-D for Advertising TE Node Capabilities
Oct 05 First version WG I-D for Automatic discovery of MPLS-TE mesh
There are two personal submissions which address these topics:
I propose that we move these into the WG and then kick the tires
