Hi Quan,
As per [1]:
A PCE initiating a new LSP, can include the association group
information. This is done by including the ASSOCIATION Object in a
PCInitiate message.
So when a new LSP is created by PCE, you could still indicate the association.
The association is not limited to existing LSPs.
Hope this helps! Let me know if I understood your question correctly!
Regards,
Dhruv

Hi Dhruv,
Thank you for the reply!O(∩_∩)O~
I agree two created PCE-initiated LSPs may be associated by ASSOCIATION object
as discussed in draft-barth-pce-association-bidir.
But if there is no LSP existed, how to request a bi-directional TE LSP from PCE
in PCE initiated operation?

Subject: [Pce] A question about RFC8281 PCE-initiated LSPs.
Hi all,
I encountered a problem as following shown.O(∩_∩)O~
As defined in RFC5440,the PCC-initiated LSPs creation uses the B bit in RP
object of PCReq message to indicate the direction of the TE LSP.
When set, the PCC requests a bi-directional TE LSP and when cleared, the TE LSP
is unidirectional.
And in stateful PCE, RFC8281 proposed the PCE-initiated LSPs and the PCE could
send a PCInitiate message to the PCC to request the creation of an LSP.
The PCInitiate message carry the Objects including SRP, LSP ,END-POINTS and
ERO. But no B bit in SRP object.
How to configure the direction of the TE LSP in PCE-initiated operation?
Best Regards,
Quan Xiong
