Thanks for any insight.
I want to use MPLS L3VPN over SR-TE Policy on ASR9000.
So I configured SR-TE Policy on Ingress PE and configured vpnv4 route-policy on Egress PE.

set extcommunity color BLACK
set next-hop 1.1.1.4
elseif destination in (74.2.1.0/24) then
set extcommunity color GREEN
set next-hop 1.1.1.4
endif
pass
end-policy

Ingress PE received vpnv4 prefix information with color community.

But L3VPN traffic didn't use SR-TE Policy.

Anything missing here in the configuration?
Or does SR-TE Policy still not support MPLS L3VPN?
As additional information, EVPN-VPWS over SR-TE Policy has succeeded.
Thanks,

Hi Soushi,
This feature is not supported yet in 6.4.2. It will be supported in 6.5.2.

As an additional comment, I posted an external article on CCO related to dynamic BGP SRTE policies, https://www.cisco.com/c/en/us/support/docs/ip/border-gateway-protocol-bgp/213934-understanding-bgp-dynamic-segment-routin.html.
