Hi Daniel:
In the section 5.3, "PCE Discovery", you said "Mechanisms that
rely on advertising
or querying PCE locations across domains or provider boundaries
are undesirable.".
I want to know why it is an "undesirable" way.
For the record, we has in the WG, long discussion on whether we should
advertise PCE across domains using for example BGP for that matter.
There was a good consensus not to, considering the limited number of
interconnected domains. The advantage was limited and introduces other
issues (security) ...
Thanks.
JP.
Can you elaborate on your point of view?
Thanks
Yuanlin
