Hello
i have a :C8500L-8S4X connect to NCS540-CISCO
so my problem i can't ping sub-interface from this router to sub-interface NCS540 ,
so please how i can resolve this problem that i can ping to sub-interfce point-point NCS540 CISCO
so you wil have configuration C8500L

That configuration looks fine and should allow pinging the NCS540 address. What does the configuration for the interface(s) on the NCS540 look like? Is the interface up?

Hello
This configuration in NCS 540 point-to-ponit to C8500L-8S4X
interface TenGigE0/0/0/22.3022 l2transport
description INBMI
encapsulation dot1q 3022
rewrite ingress tag pop 1 symmetric
and this configuration is UP UP
so how i can edit configuration that allow ping from 8500 to NCS540
I wait a reply
Thanks

Hello @Dhikra Marghli,
Please provide us the NCS and c8500 output of #show ip interface brief command.

It is a P2P connection? Why l2transport? No VPLS needed.

Thanks for your reply
Telecom operator who works on this nCS54 equipment cannot change configuration on NCS 540 and he tells me how to change configuration in interafce C8500L-8S4X so that allows ping interface from NCS54 to C8500L-8S4X ??
so please how i can change configuration in C8500L-8S4X ???

Why are you using an l2transport configuration on the NCS540? Is this part of an L2VPN where you are transporting Ethernet frames from one attachment circuit to another? If not, and you only want an L3 interface, get rid of the "l2transport" keyword and replace the "rewrite" config with "ipv4 address 172.25.40.161/30"

Operator Telecom send me from NCS540 :
and he say me that this interface in NCS540 is conneted directly to C8500L-8S4X ( p2P) . Yes , interface in NCS540 is L2VPN
so i can't unterstand how i can edit configuration C8500L-8S4X !!!! that allow to interface in NCS540 !!

The address 172.25.40.161 must be attached to an L3 construct (interface), while NCS540 int TenGigE0/0/0/22.3022 is an L2 construct. Has the operator of the NCS540 said where this IP address is attached? To a BVI perhaps?
The L2VPN config from the NCS540 is incomplete, as it is only showing the TenGigE0/0/0/22.3022 attachment circuit and not how/where the ethernet frames are being transported by the 540. Ask the operator for the complete L2VPN config for your service.

Operator say me that configuration is from NCS540 cisco is interface L2
and this NCS540 is connted to router Busniess-PE
this B-PE is conneted to C8500L-8S4X
so configuration in B-PE router : ASR9K has interface L3
interface TenGigE0/0/0/22.3022
encapsulation dot1q 3022
ip address 172.25.40.161 255.255.255.252
so Operator Telecom say me to edit configuration in 8500L !
so please how i can resolve this problem that allow ping from B-PE to 8500L
Thanks

Hello
i explain you topologie but Operator insist change configuration in 8500L !!!
