Re: [CCAMP] OVRLY - signaling extensions

[Rajan Rao <[e-mail]>]

My understanding is that a “Cookie” is a network-Id/path-id.  It won’t give info CE is looking for.   What I understood from side discussions is that Crankback will be used to convey info back to CE!!

Hi Rajan,

I would say “by cookie” if I understand your question correctly.


Thanks

One more question:

In case of PCE,  I assume CE is the one talking to PCE (fig-2 in uni-app draft).
In cases where CE reachability is not known & PE1 is the one talking to PCE (say CE makes a request to PE1 first),  how do you communicate PE2 info back to CE?

Thx
Rajan

Hi Rajan,

I think your question is a general question, and should be out of scope of “LSP diversity” topic, :)

However, there are lots of approaches for CE to know why “PE1” should be picked up besides the way mentioned by Dieter below, e.g, qualified TE information (besides reachability) known by CE, manual configuration, or PCE can help as described in draft-zhang-ccamp-gmpls-uni-app<http://tools.ietf.org/id/draft-zhang-ccamp-gmpls-uni-app-05.txt>.


Thanks

My question on your uses cases was the following:

How does CE know which PE to talk to for the first LSP setup?  What is the assumption?
assuming that the CE does not have any information other than the destination CE is reachable via
both PEs , it will just pick one arbitrarily.


Thanks,
Dieter





Thx Lou for session notes.
