Now we have real label (UHP) for CT routex. So it is a swap. Still don’t see the P4 programmed:

Yet to try exp-null/UHP label. May need code-change on my side.

Label-mode per-prefix-label exists in config currently:

core#show running-config vrf eantc-bgp-ct-gold

vrf definition eantc-bgp-ct-gold

rd 91136:2359300

rt4import 91136:2359300

rt4export 91136:2359300

rt6import 91136:2359300

rt6export 91136:2359300

clr4import 128

clr4export 128

clr6import 128

clr6export 128

label4mode per-prefix

exit

Thanks

[External Email. Be cautious of content]

or you can do

vrf def xxxx
label-mode per-prefix....
