ESI value are not applied to the devices: ESI value that specified in the payload is not flushed to the devices 
Hi YevgenyWe couldn't reproduce the issue on our system. We see the esi-value being propagated to the device.Can you please provide us with the system details where you are facing this issue.Thanks.NSO UI: ============= admin/Public12345!Devices:=============Access to devices: ssh: 10.56.58.145 nso5721/Public1234!From that VM SSH: admin/Public1234!192.168.122.204 PE-A192.168.122.143 PE-B192.168.122.240 PE-CService For example=============Hi YevgeniWe checked your setup and could see that there are multiple services pushing the esi-value on the same interface(PE-B). Below are those services and esi-values:L2VPN_NM-PBB-CUSTOM-SRTE-ODN-430 (esi-value 00.01.00.ac.ce.55.00.04.30)L2VPN_NM-ELAN-MH-340 (esi-value 00.01.00.ac.ce.77.00.0a.11)L2VPN_NM-PBB-CUSTOM-390 (esi-value 00.01.00.ac.ce.55.00.03.90)L2VPN_NM-ETREE-MH-380 (esi-value 00.01.00.ac.ce.55.00.0a.00)The device PE-B is having the esi-value 0 00.01.00.ac.ce.55.00.04.30 present which is posted through the L2VPN_NM-PBB-CUSTOM-SRTE-ODN-430 service.These multiple services are shifting the esi-value on the device and hence you are not able to see the required value.Thanks,NikhilPlease clean up extra services and re-deploy the service you want to useThis is not 100% accurate. Each service is using its own dedicated sub interface Hi Yevgeny,You mentioned XR supported sub-ifs for ethernet-segments, but was not able to get passed the following error:<div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"><pre>RP/0/RSP0/CPU0:PE2(config-evpn-ac-es)#show configuration failedWed Mar 23 23:49:43.368 UTC!!
