1. 配置接口类型及IP地址
[CE1-GigabitEthernet0/0/0]ip add 10.1.1.1 24
[CE2-GigabitEthernet0/0/0]ip add 10.1.1.2 24
[PE]vlan batch 10 20
[PE-GigabitEthernet0/0/1]port link-type trunk
[PE-GigabitEthernet0/0/1]port trunk allow-pass vlan 10
[PE-GigabitEthernet0/0/2]port link-type trunk
[PE-GigabitEthernet0/0/2]port trunk allow-pass vlan 20
2. 在PE上配置MPLS基本能力，使能MPLS L2VPN
[PE-LoopBack1]ip add 3.3.3.3 32
[PE]mpls lsr-id 3.3.3.3
[PE]mpls
[PE]mpls l2vpn
3. 在PE上创建一条从CE1到CE2的本地CCC连接
[PE]int Vlanif 10
[PE]int Vlanif 20
[PE]ccc ce1_ce2 interface Vlanif 10 out-interface Vlanif 20
4. 验证配置
