Hello, friend!
If they are in the same VLAN, you can use proxy ARP to implement interworking.
Run the following command:
huawei(config)#arp proxy enable
huawei(config)#interface vlanif#vlanid //The VLAN here refers to the VLAN to which you belong.
huawei(config-if-vlanif100)#arpproxy enable
I hope it helps you.
Thanks!
