在一台华为ATN950B上配置如下(默认配置未列出）： # undo lldp enable # bfd # mpls lsr-id 1.1.1.1 mpls # mpls l2vpn # interface GigabitEthernet0/1/0 undo shutdown # interface GigabitEthernet0/1/0.31 vlan-type dot1q 31 ip address 3.100.85.214 255.255.255.252 mpls # ip route-static 1.1.1.2 255.255.255.255 3.100.85.213 # static-lsp ingress ingress-1 destination 1.1.1.2 32 nexthop 3.100.85.213 out-label 101 static-lsp egress egress-1 incoming-interface GigabitEthernet0/1/0.31 in-label 102 # interface GigabitEthernet0/1/5 undo shutdown mpls static-l2vc destination 1.1.1.2 10001 transmit-vpn-label 111 receive-vpn-label 102 control-word 1槽位为D1EME8T盘，在输入如下命令行时总是提示不对： [HUAWEI]interface GigabitEthernet 0/1/5 [HUAWEI-GigabitEthernet0/1/5]mpls l2vpn pw bfd Error: The current interface does not be configured with VC. 手册上说动态BFD支持静态PW，为什么配置不起呢？一直搞不懂，翻了1天资料了，仍然无解，请教下各位大大，不胜感激！
