组网需求
7-9 CE1 CE2 分别通过 VLAN 方式接入 PE1 PE2
CE1 CE2 之间建立 Martini 方式的 VLL ,使 CE1 CE2 的用户网络可以互通。
7-9 配置 Dot1q 终结子接口接入 VLL 组网图

华为 huawei 交换机 配置 Dot1q 终结子接口接入 VLL 示例-LMLPHP
配置思路
采用如下的思路配置 Dot1q 子接口接入 VLL
1. 在骨干网相关设备( PE P )上配置路由协议实现互通,并使能 MPLS
2. 本例使用缺省隧道策略,建立 LSP 作为传输业务数据的隧道。
3. PE 上使能 MPLS L2VPN ,并创建 VC 连接。
4. PE 连接 CE 的接口上配置 Dot1q 子接口接入 VLL
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 7-9 配置 CE PE P 的各接口所属 VLAN VLANIF 接口的 IP 地址

[PE1-GigabitEthernet0/0/2] port hybrid pvid vlan 20
[PE1-GigabitEthernet0/0/2] port hybrid tagged vlan 20
[PE1-GigabitEthernet0/0/2] quit
[PE1] interface vlanif 20
[PE1-Vlanif20] ip address 10.1.1.1 24
[PE1-Vlanif20] quit
# 配置 P
<HUAWEI> system-view
[HUAWEI] sysname P

[P-Vlanif20] quit
[P] interface vlanif 30
[P-Vlanif30] ip address 10.2.2.2 24
[P-Vlanif30] quit
# 配置 PE2
<HUAWEI> system-view
[HUAWEI] sysname PE2
[PE2] vlan batch 30
[PE2] interface gigabitethernet 0/0/1

[PE2] interface vlanif 30
[PE2-Vlanif30] ip address 10.2.2.1 24
[PE2-Vlanif30] quit
步骤 2 MPLS 骨干网上配置 IGP ,本示例中使用 OSPF
配置 OSPF 时,注意需要发布 PE1 P PE2 作为 LSR ID 32 Loopback 接口地址。
# 配置 PE1
[PE1] router id 1.1.1.1
[PE1] interface loopback 1
[PE1-LoopBack1] ip address 1.1.1.1 32
[PE1-LoopBack1] quit
[PE1] ospf 1
[PE1-ospf-1] area 0
[PE1-ospf-1-area-0.0.0.0] network 1.1.1.1 0.0.0.0
[PE1-ospf-1-area-0.0.0.0] network 10.1.1.1 0.0.0.255
[PE1-ospf-1-area-0.0.0.0] quit
[PE1-ospf-1] quit
# 配置 P
[P] router id 2.2.2.2
[P] interface loopback 1
[P-LoopBack1] ip address 2.2.2.2 32
[P-LoopBack1] quit
[P] ospf 1
[P-ospf-1] area 0
[P-ospf-1-area-0.0.0.0] network 2.2.2.2 0.0.0.0

[P-ospf-1-area-0.0.0.0] network 10.2.2.2 0.0.0.255
[P-ospf-1-area-0.0.0.0] quit
[P-ospf-1] quit
# 配置 PE2
[PE2] router id 3.3.3.3
[PE2] interface loopback 1
[PE2-LoopBack1] ip address 3.3.3.3 32
[PE2-LoopBack1] quit
[PE2] ospf 1
[PE2-ospf-1] area 0
[PE2-ospf-1-area-0.0.0.0] network 3.3.3.3 0.0.0.0
[PE2-ospf-1-area-0.0.0.0] network 10.2.2.1 0.0.0.255
[PE2-ospf-1-area-0.0.0.0] quit
[PE2-ospf-1] quit
# 配置完成后, PE1 P PE2 之间应能建立 OSPF 邻居关系,执行 display ospf peer
令可以看到邻居状态为 Full 。执行 display ip routing-table 命令可以看到 PE 之间学习
到对方的 Loopback1 接口路由。以 PE1 的显示为例:
[PE1] display ospf peer
OSPF Process 1 with Router ID 1.1.1.1

[PE1] display ip routing-table

------------------------------------------------------------------------------
Routing Tables: Public

1.1.1.1/32 Direct 0 0 D 127.0.0.1 LoopBack1
2.2.2.2/32 OSPF 10 1 D 10.1.1.2 Vlanif20
3.3.3.3/32 OSPF 10 2 D 10.1.1.2 Vlanif20
10.1.1.0/24 Direct 0 0 D 10.1.1.1 Vlanif20
10.1.1.1/32 Direct 0 0 D 127.0.0.1 Vlanif20
10.2.2.0/24 OSPF 10 2 D 10.1.1.2 Vlanif20

127.0.0.1/32 Direct 0 0 D 127.0.0.1 InLoopBack0
步骤 3 MPLS 骨干网上配置 MPLS 基本能力和 LDP
# 配置 PE1
[PE1] mpls lsr-id 1.1.1.1
[PE1] mpls
[PE1-mpls] quit
[PE1] mpls ldp
[PE1-mpls-ldp] quit
[PE1] interface vlanif 20
[PE1-Vlanif20] mpls
[PE1-Vlanif20] mpls ldp
[PE1-Vlanif20] quit
# 配置 P
[P] mpls lsr-id 2.2.2.2
[P] mpls
[P-mpls] quit
[P] mpls ldp
[P-mpls-ldp] quit
[P] interface vlanif 20
[P-Vlanif20] mpls
[P-Vlanif20] mpls ldp
[P-Vlanif20] quit
[P] interface vlanif 30
[P-Vlanif30] mpls
[P-Vlanif30] mpls ldp
[P-Vlanif30] quit
# 配置 PE2
[PE2] mpls lsr-id 3.3.3.3
[PE2] mpls
[PE2-mpls] quit
[PE2] mpls ldp
[PE2-mpls-ldp] quit
[PE2] interface vlanif 30
[PE2-Vlanif30] mpls
[PE2-Vlanif30] mpls ldp
[PE2-Vlanif30] quit
步骤 4 PE 之间建立远端 LDP 会话
# 配置 PE1
[PE1] mpls ldp remote-peer 3.3.3.3
[PE1-mpls-ldp-remote-3.3.3.3] remote-ip 3.3.3.3
[PE1-mpls-ldp-remote-3.3.3.3] quit
# 配置 PE2
[PE2] mpls ldp remote-peer 1.1.1.1
[PE2-mpls-ldp-remote-1.1.1.1] remote-ip 1.1.1.1
[PE2-mpls-ldp-remote-1.1.1.1] quit
上述配置完成后,在 PE1 上执行 display mpls ldp session 命令查看 LDP 会话的建立情
况,可以看到增加了与 PE2 的远端 LDP 会话。
PE1 的显示为例:
[PE1] display mpls ldp session
LDP Session(s) in Public Network
Codes: LAM(Label Advertisement Mode), SsnAge Unit(DDDD:HH:MM)
A '*' before a session means the session is being deleted.
------------------------------------------------------------------------------
PeerID Status LAM SsnRole SsnAge KASent/Rcv
------------------------------------------------------------------------------
2.2.2.2:0 Operational DU Passive 0000:15:29 3717/3717
3.3.3.3:0 Operational DU Passive 0000:00:00 2/2
------------------------------------------------------------------------------
TOTAL: 2 session(s) Found.
步骤 5 PE 上使能 MPLS L2VPN ,并创建 VC 连接
# 配置 PE1 :在接入 CE1 的接口 gigabitethernet0/0/1.1 上创建 VC
[PE1] mpls l2vpn
[PE1-l2vpn] quit
[PE1] vcmp role silent
[PE1] interface gigabitethernet0/0/1
[PE1-GigabitEthernet0/0/1] port link-type hybrid
[PE1-GigabitEthernet0/0/1] quit
[PE1] interface gigabitethernet0/0/1.1
[PE1-GigabitEthernet0/0/1.1] dot1q termination vid 10
[PE1-GigabitEthernet0/0/1.1] mpls l2vc 3.3.3.3 101
[PE1-GigabitEthernet0/0/1.1] quit
# 配置 PE2 :在接入 CE2 的接口 gigabitethernet0/0/2.1 上创建 VC
[PE2] mpls l2vpn
[PE2-l2vpn] quit
[PE2] vcmp role silent
[PE2] interface gigabitethernet0/0/2
[PE2-GigabitEthernet0/0/2] port link-type hybrid
[PE2-GigabitEthernet0/0/2] quit
[PE2] interface gigabitethernet0/0/2.1
[PE2-GigabitEthernet0/0/2.1] dot1q termination vid 10
[PE2-GigabitEthernet0/0/2.1] mpls l2vc 1.1.1.1 101
[PE2-GigabitEthernet0/0/2.1] quit
步骤 6 验证配置结果
PE 上查看 L2VPN 连接信息,可以看到建立了一条 L2 VC ,状态为 UP
PE1 的显示为例:
