Hi @Harold Ritter ,
I am sorry to ask questions on SR-TE. Whenever i observe any issue in Segment routing , only your name comes to my mind as you helped me earlier on Segment routing related issue. Thanks a lot for that.
Now i come up with different issue . I am using Nokia SR router in my topology .
we have connected PCE to all the edge routers(PCC) (CER1_1, CER1_2, CER1_3, CER1_4) and trying to bring up SR-TE LSP with PCEP Controller on all edge routers.
PCE shows PCEP connection with all 4 edge routers as mentioned below .I see BGP is UP and SR-OSPF also UP on PCC routers.

Router id of CER1-1 : 92.168.96.23
Router id of CER1-4: 92.168.97.16
Only with CER1_1 to CER1_2 / CER2_1 to CER1_1 we have SR-TE LSP is up with PCE
Now problem is SR-TE lsp is not coming up between CER1_1 to CER1_4 if we configure SR TE lsp with PCE.
Please note that Without PCE , SR-TE LSP is coming up between CER1_1 to CER1_4.
Kindly check this and provide your comment on this issue.
