问题描述：

华为DCN配置翻译成华三配置。明显看到华三的配置要比华为多很多。正常使用下必须要按照华三案例里所有的的命令配置，dcn功能才会正常使用吗？

华为配置：

interface GigabitEthernet0/1/1

undo shutdown dcn # interface LoopBack1023 description DCN loopback interface ip binding vpn-instance __dcn_vpn__ ip address 128.1.0.1 255.255.0.0 # ospf 65534 vpn-instance __dcn_vpn__ description DCN ospf create by default opaque-capability enable hostname vpn-instance-capability simple area 0.0.0.0 network 0.0.0.0 255.255.255.255

华三官网案例：

# 配置全局使能DCN。

<DeviceB> system-view

[DeviceB] dcn

[DeviceB-dcn] ne-id 300003

[DeviceB-dcn] ne-ip 33.3.3.3 32

[DeviceB-dcn] quit

# 配置运行DCN功能的VPN。

[DeviceB] ip vpn-instance dcn_vpn

[DeviceB-vpn-instance-dcn_vpn] quit

# 配置DCN使用的LoopBack接口。

[DeviceB] interface loopback 4095

[DeviceB-LoopBack4095] ip binding vpn-instance dcn_vpn

[DeviceB-LoopBack4095] quit

# 配置全局使能LLDP。

[DeviceB] lldp global enable

# 配置LLDP报文的管理地址封装指定LoopBack接口4095的IP地址；配置收到LLDP报文后下发ARP表项。

[DeviceB] interface gigabitethernet 3/1/1

[DeviceB-GigabitEthernet3/1/2] quit

# 配置DCN使用的子接口、地址借用和VLAN类型。

# 配置OSPF进程和区域。

[DeviceB] ospf 65535 vpn-instance dcn_vpn

# 配置子接口链路类型为P2P。

[DeviceB] interface gigabitethernet 3/1/1.4093
