Good day! I have been working on implementing PCE-initiated LSPs from a Cisco PCE to Junos PCC for a SR-MPLS based network with multiple domains. It is working good, but for an unknown reason the color attribute of the SRTE tuple is not taken by the Juniper PCC. I have tried with Cisco PCC and it accepts the color as an attribute of the SRTE policy.
From debugs, I don't see any clue about the reason of the issue. So I would like to know if something else needs to be configured on the PCE or if there is known interoperability issue to exchange this SRTE tuple attribute.
Below configuration on the PCC side and some debugs on Cisco PCE and Junos PCC. Cisco to Cisco is working perfectly.
#PCEP Configuration on PCC (Junos)
pce pccd {
local-address 34.34.34.34;
destination-ipv4-address 100.200.100.200;
destination-port 4189;
pce-type active stateful;
lsp-provisioning;
spring-capability;
}
#PCEP message received on PCC

It shows other attributes but not the srte color.

Hope someone can help me to clarify this behaviour.
Thanks!
