组网需求
如 图 7-13 ， CE1 、 CE3 属于 VPN-A ， CE2 、 CE4 属于 VPN-B ； VPN-A 使用的 VPN-target
属性为 111:1 ， VPN-B 使用的 VPN-target 属性为 222:2 。不同 VPN 用户之间不能互相访
问。
图 7-13 配置 Dot1q 终结子接口接入 L3VPN 组网图
配置思路
采用如下的思路配置 Dot1q 子接口接入 L3VPN ：
- 骨干网中，与 CE 相连的 PE 上需配置 VPN 实例，并把与 CE 相连的接口和相应的 VPN
实例绑定；绑定之后配置与 CE 相连的接口的 IP 地址。
- PE 与 PE 之间配置 OSPF 实现 PE 之间的互通。
- 配置 MPLS 基本能力和 MPLS LDP ，建立 MPLS LSP 。
- 配置 MP-IBGP 交换 VPN 路由信息。
- CE 与 PE 之间配置 EBGP 交换 VPN 路由信息。
- 在 PE 连接 CE 的接口上配置 Dot1q 子接口接入 L3VPN 。
说明
VCMP 的角色是 Client 时，不能配置 VLAN 终结子接口。
操作步骤
步骤 1 在 MPLS 骨干网上配置 IGP 协议，实现骨干网 PE 和 P 的互通
配置 PE1 。

当 PE 上有多个绑定了同一个 VPN 的接口，则使用 **ping -vpn-instance** 命令 Ping 对端 PE 接入的 CE
时，要指定源 IP 地址，即要指定 **ping -vpn-instance** *vpn-instance-name* **-a** *source-ip-address*
*dest-ip-address* 命令中的参数 **-a** *source-ip-address* ，否则可能 Ping 不通。
