Hello,
We having problem in creating L2VPN EVPN using NCS-540.
We already have multiple NCS-5508 and NCS-55A2 in our network, and we have no issue in running EVPNs. But the same config is not working on NCS-540.
The control plane seems to be fine as the PE devices are successfully exchanging the MAC addresses but the traffic is not flowing across the VPN.
Below are some configuration details:

Please note that the exact same config is working on other NCS55A2 & NCS5508 nodes. The problem is only being faced on NCS540.
Are we missing something? Do we need to do any additional config on the NCS540?
Regards,
