The following about DCN network planning, the error is

A. The IP address of U2000 is 129.9.0.100/24, and the IP address of the gateway NE it manages is 129.9.0.2/24. If the U2000 wants to communicate with a network element with an IP address of 133.168.0.2/24 that is connected to a gateway network element through IP over DCC, the U2000 needs to be directly connected to the gateway network element.

B. Huawei transport domain network elements support three communication protocols for DCN networking, among which the HWECC protocol is a private communication protocol developed by Huawei for DCN networking of transport domain network elements.

C. The network management server and each managed network element adopt in-band networking or out-of-band networking for communication. In-band networking refers to the networking mode in which the U2000 uses the service channels provided by the managed devices to manage the devices in the network.

D. Huawei transport domain network elements all support the HWECC protocol, and the default physical transmission channel is D1 to D12 bytes. When the network element ID is set, the ECC communication can be carried out without any configuration after plugging in the optical fiber.

The following statement about PTN's VPLS technology is wrong,

A. VSI is a virtual layer 2 forwarding entity, which defines the number of members of the VPLS domain on the PE, similar to a virtual switch

B. Need to manually configure the split horizon group to avoid the loop of Full-mesh VPLS

C. PE only needs to determine the forwarding of the Ethernet frame based on the VLAN ID in the user message without other parameters (such as the destination MAC address in the message, etc.), whether it is forwarded directly to the CE or to the PW through the PW Peer PE

D. VPLS (Virtual Private LAN Services), is a kind of service similar to LAN provided on MPLS (Multiprotocol Label Switching) network
