Re: [CCAMP] poll on making draft-zhang-mpls-tp-rsvpte-ext-associated-lsp-04 a WG document

Hi Jie

Thank you for the comments. :)

According to the description in section 4

"The Association ID MUST be set to its own signaled LSP ID (default); if 
known, it MAY be set to the LSP ID of the associated reverse LSP."
"The first 16-bits MUST be set to its own tunnel ID (default); if known, 
it May be set to the tunnel ID of the associated reverse tunnel."

What about the revision like this: "if known, it MAY be set to the LSP ID 
of the associated reverse LSP or inherited from the corresponding recovery 
LSP."

I will address all the comments in the next version.

Best regards 

Fei

Re: [CCAMP] poll on     making

Hi authors,

One quick comment here.

In section 3.3 recovery considerations, it says
" LSP3... can share the same TE tunnel with LSP1 or not. ... This can be 
done by inserting the Extended ASSOCIATION object in LSP3's Path message 
with the same value as in LSP1's Path message."

This means LSP3 may use LSP1's IDs in the Extended ASSOCIATION object in 
its Path message, which may contain Tunnel_Num and LSP_ID different from 
its own and LSP2's.

However, in section 4, the specification of Association ID and Extended 
Association ID field says:
 o Association ID:
   The Association ID MUST be set to its own signaled LSP ID (default); if 
known, it MAY be set to the LSP ID of the associated reverse LSP.
 o Extended Association ID:
   ... the first 16-bits MUST be set to its own tunnel ID (default); if 
known, it May be set to the tunnel ID of the associated reverse tunnel.

Hence the two specifications conflict with each other.

Regards,
Jie
