Hi, JP:

I have read your draft, draft-vasseur-pce-brpc-01.txt, and I have a question.

In Draft:

   Step 2: PCE(n) computes VSPT(n) made of the list of shortest

   constrained path(s) between every BR-en(j,n) and the TE LSP

   destination using a suitable path computation algorithm (e.g.  CSPF)

   and returns the computed VSPT(n) to PCE(n-1).

 

 My question is: How does PCE know who are the entry nodes or exit nodes of a domain? Lack of this information, PCE can not compute the path in the domain. If the information is included in the predetermined domain path set?

Maybe the question is naïve and simple; could you give me some explanations?

 

Thanks

 XingFeng Jiang
