Re: [Pce] TED for inter area LSP establisment

["Adrian Farrel" <adrian at olddog.co.uk>]

Hi Pavan,

There is no mandated way to construct this TED.

A way this might be done is by the centralized PCE participating passively 
in the IGP in each area (for example through an IP tunnel). Another way 
might be by having a proxy in the area that sends the area's TED out to the 
centralized PCE. A third way might be for the PCE to read the TED from a 
specific router using the TED MIB or some other mechanism.

Of course, a centralized PCE might not be the best way to compute inter-area 
paths.
