配置BGP方式VPWS本地连接示例
两个CE设备连接在同一个PE设备上，可以通过建立BGP方式VPWS本地连接，实现CE设备之间的互通。
操作步骤
- 配置CE
# 配置CE1。
<HUAWEI> system-view[~HUAWEI] sysname CE1
[*HUAWEI] commit
[~CE1] interface gigabitethernet 1/0/0
[*CE1-GigabitEthernet1/0/0] ip address 10.1.1.1 24
[*CE1-GigabitEthernet1/0/0] quit
[*CE1] commit# 配置CE2。
<HUAWEI> system-view[~HUAWEI] sysname CE2
[*HUAWEI] commit
[~CE2] interface gigabitethernet 1/0/0
[*CE2-GigabitEthernet1/0/0] ip address 10.1.1.2 24
[*CE2-GigabitEthernet1/0/0] quit
[*CE2] commit - 在PE上使能MPLS基本功能

[*PE-mpls-l2vpn-vpn1-ce-ce2] quit[*PE-mpls-l2vpn-vpn1] quit[*PE] commit - 验证配置结果
完成上述配置后，在PE上执行display mpls l2vpn connection命令，可以看到建立了两条VPWS本地连接，且状态为Up。
[~PE] display mpls l2vpn connection2 total connections, connections: 2 up, 0 down, 2 local, 0 remote, 0 unknown VPN name: vpn1, 2 total connections, connections: 2 up, 0 down , 2 local, 0 remote, 0 unknown CE name: ce1, id: 1, Rid type status peer-id route-distinguisher interface primary or not ---------------------------------------------------------------------------- 2 loc up --- --- GigabitEthernet1/0/0 primary CE name: ce2, id: 2, Rid type status peer-id route-distinguisher interface primary or not ---------------------------------------------------------------------------- 1 loc up --- --- GigabitEthernet2/0/0 primary
CE1与CE2能够Ping通。
