Error Message    

%FORWARDING-FWD_L2HAL-2-CONFIG_NOT_SUPPORTED Engine 3 LC cannot be edge and core simultaneously. Revert those configs.

A runtime error occurred in GSR L2HAL module. The reason for the failure is also displayed.

Recommended Action   
Revert the config wherever the same LC is configured as both edge facing and core facing card.




the setup is simple:------>SW1---XR2----XR3----XR4----SW2


the l2vpn config is in XR2 and XR4


here are the configs which is working fine:-


interface GigabitEthernet0/9/0/1.101 l2transport
 dot1q vlan 101

mpls oam

 pw-class CLASS1
  encapsulation mpls
 bridge group 1
  bridge-domain BAR
   interface GigabitEthernet0/4/0/0.101
   vfi VFI1
    neighbor pw-id 101
