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 。

[P-ospf-1-area-0.0.0.0] quit
[P-ospf-1] quit
配置 PE2 。
<HUAWEI> system-view
[HUAWEI] sysname 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] vlan batch 60
[PE2] interface gigabitethernet 0/0/3
[PE2-GigabitEthernet0/0/3] port link-type hybrid

[PE2-ospf-1-area-0.0.0.0] quit
[PE2-ospf-1] quit
配置完成后， PE1 和 P 、 P 和 PE2 之间应能建立 OSPF 邻居关系，执行 display ospf peer
命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 路由。
以 PE1 的显示为例：
[PE1] display ip routing-table
Route Flags: R - relay, D - download to fibȀ T - to vpn-instance
Routing Tables: Public
Destinations : 8 Routes : 8
Destination/Mask Proto Pre Cost Flags NextHop Interface

3.3.3.3/32 OSPF 10 2 D 7.7.7.8 Vlanif30
6.6.6.0/24 OSPF 10 2 D 7.7.7.8 Vlanif30

127.0.0.1/32 Direct 0 0 D 127.0.0.1 InLoopBack0
[PE1] display ospf peer

Retrans timer interval: 5

步骤 2 在 MPLS 骨干网上配置 MPLS 基本能力和 MPLS LDP ，建立 LDP LSP
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 30
[PE1-Vlanif30] mpls
[PE1-Vlanif30] mpls ldp
[PE1-Vlanif30] 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 30
[P-Vlanif30] mpls
[P-Vlanif30] mpls ldp
[P-Vlanif30] quit
[P] interface vlanif 60
[P-Vlanif60] mpls
[P-Vlanif60] mpls ldp
[P-Vlanif60] 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 60
[PE2-Vlanif60] mpls
[PE2-Vlanif60] mpls ldp
[PE2-Vlanif60] quit
上述配置完成后， PE1 与 P 、 P 与 PE2 之间应能建立 LDP 会话，执行 display mpls ldp
session 命令可以看到显示结果中 Status 项为" Operational "。执行 display mpls ldp
lsp 命令，可以看到 LDP LSP 的建立情况。
以 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

TOTAL: 1 session(s) Found.
[PE1] display mpls ldp lsp

3.3.3.3/32 1025/1025 2.2.2.2 7.7.7.8 Vlanif30
TOTAL: 5 Normal LSP(s) Found.
TOTAL: 1 Liberal LSP(s) Found.
TOTAL: 0 Frr LSP(s) Found.
A '*' before an LSP means the LSP is not established
A '*' before a Label means the USCB or DSCB is stale
A '*' before a UpstreamPeer means the session is stale
A '*' before a DS means the session is stale
A '*' before a NextHop means the LSP is FRR LSP
步骤 3 在 PE 设备上配置 VPN 实例，将 CE 接入 PE
配置 PE1 。
[PE1] ip vpn-instance vpna
[PE1-vpn-instance-vpna] route-distinguisher 100:1
[PE1-vpn-instance-vpna-af-ipv4] vpn-target 111:1 both

[PE1-GigabitEthernet0/0/1.1] arp broadcast enable
[PE1-GigabitEthernet0/0/1.1] quit
[PE1] interface gigabitethernet 0/0/2
[PE1-GigabitEthernet0/0/2] port link-type hybrid
[PE1-GigabitEthernet0/0/2] quit
[PE1] interface gigabitethernet 0/0/2.1
[PE1-GigabitEthernet0/0/2.1] dot1q termination vid 20
[PE1-GigabitEthernet0/0/2.1] ip binding vpn-instance vpnb
[PE1-GigabitEthernet0/0/2.1] ip address 10.2.1.2 24
[PE1-GigabitEthernet0/0/2.1] arp broadcast enable
[PE1-GigabitEthernet0/0/2.1] quit
配置 PE2 。
[PE2] ip vpn-instance vpna
[PE2-vpn-instance-vpna] route-distinguisher 200:1
[PE2-vpn-instance-vpna-af-ipv4] vpn-target 111:1 both

[PE2-GigabitEthernet0/0/2.1] arp broadcast enable
[PE2-GigabitEthernet0/0/2.1] quit
按 图 7-13 配置 CE1 的接口 IP 地址。 CE2 、 CE3 和 CE4 的配置与 CE1 类似，不再赘述。
<HUAWEI> system-view
[HUAWEI] sysname CE1
[CE1] vlan batch 10
[CE1] interface gigabitethernet 0/0/1
[CE1-GigabitEthernet0/0/1] port link-type hybrid
[CE1-GigabitEthernet0/0/1] port hybrid pvid vlan 10
[CE1-GigabitEthernet0/0/1] port hybrid tagged vlan 10
[CE1-GigabitEthernet0/0/1] quit
[CE1] interface vlanif 10
[CE1-Vlanif10] ip address 10.1.1.1 24
[CE1-Vlanif10] quit
配置完成后，在 PE 设备上执行 display ip vpn-instance verbose 命令可以看到 VPN 实
例的配置情况。各 PE 能 Ping 通自己接入的 CE 。
说明
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。
以 PE1 为例：
[PE1] display ip vpn-instance verbose
Total VPN-Instances configured : 2

Total IPv6 VPN-Instances configured : 0
VPN-Instance Name and ID : vpna, 1

步骤 4 在 PE 与 CE 之间建立 EBGP 对等体关系，引入 VPN 路由
配置 CE1 。 CE2 、 CE3 和 CE4 的配置与 CE1 类似，不再赘述。
[CE1] bgp 65410
[CE1-bgp] peer 10.1.1.2 as-number 100
[CE1-bgp] import-route direct
配置 PE1 。 PE2 的配置与 PE1 类似，不再赘述。
[PE1] bgp 100
[PE1-bgp] ipv4-family vpn-instance vpna
[PE1-bgp-vpna] peer 10.1.1.1 as-number 65410
[PE1-bgp-vpna] import-route direct
[PE1-bgp-vpna] quit
[PE1-bgp] ipv4-family vpn-instance vpnb
[PE1-bgp-vpnb] peer 10.2.1.1 as-number 65420
[PE1-bgp-vpnb] import-route direct
[PE1-bgp-vpnb] quit
[PE1-bgp] quit
配置完成后，在 PE 设备上执行 display bgp vpnv4 vpn-instance peer 命令，可以看到
PE 与 CE 之间的 BGP 对等体关系已建立，并达到 Established 状态。
以 PE1 与 CE1 的对等体关系为例：
[PE1] display bgp vpnv4 vpn-instance vpna peer
BGP local router ID : 1.1.1.1
Local AS number : 100
VPN-Instance vpna, Router ID 1.1.1.1:
Total number of peers : 1 Peers in established state : 1
Peer V AS MsgRcvd MsgSent OutQ Up/Down State PrefRcv
10.1.1.1 4 65410 11 9 0 00:07:25 Established 1
步骤 5 在 PE 之间建立 MP-IBGP 对等体关系
配置 PE1 。
[PE1] bgp 100
[PE1-bgp] peer 3.3.3.3 as-number 100
[PE1-bgp] peer 3.3.3.3 connect-interface loopback 1
[PE1-bgp] ipv4-family vpnv4
[PE1-bgp-af-vpnv4] peer 3.3.3.3 enable
[PE1-bgp-af-vpnv4] quit
[PE1-bgp] quit
配置 PE2 。
[PE2] bgp 100
[PE2-bgp] peer 1.1.1.1 as-number 100
[PE2-bgp] peer 1.1.1.1 connect-interface loopback 1
[PE2-bgp] ipv4-family vpnv4
[PE2-bgp-af-vpnv4] peer 1.1.1.1 enable
[PE2-bgp-af-vpnv4] quit
[PE2-bgp] quit
配置完成后，在 PE 设备上执行 display bgp peer 或 display bgp vpnv4 all peer 命令，
可以看到 PE 之间的 BGP 对等体关系已建立，并达到 Established 状态。
[PE1] display bgp peer
BGP local router ID : 1.1.1.1
Local AS number : 100
Total number of peers : 1 Peers in established state : 1
Peer V AS MsgRcvd MsgSent OutQ Up/Down State PrefRcv
3.3.3.3 4 100 12 6 0 00:02:21 Established 0
[PE1] display bgp vpnv4 all peer
BGP local router ID : 1.1.1.1
Local AS number : 100
Total number of peers : 3 Peers in established state : 3
Peer V AS MsgRcvd MsgSent OutQ Up/Down State PrefRcv
3.3.3.3 4 100 12 18 0 00:09:38 Established 0

VPN-Instance vpnb, Router ID 1.1.1.1:
10.2.1.1 4 65420 21 22 0 00:17:10 Established 1
步骤 6 检查配置结果
在 PE 设备上执行 display ip routing-table vpn-instance 命令，可以看到去往对端 CE
的路由。
以 PE1 的显示为例：
[PE1] display ip routing-table vpn-instance vpna
Route Flags: R - relay, D - download to fibȀ T - to vpn-instance
Routing Tables: vpna
Destinations : 3 Routes : 3
Destination/Mask Proto Pre Cost Flags NextHop Interface

10.3.1.0/24 IBGP 255 0 RD 3.3.3.3 Vlanif30
[PE1] display ip routing-table vpn-instance vpnb
Route Flags: R - relay, D - download to fibȀ T - to vpn-instance
Routing Tables: vpnb
Destinations : 3 Routes : 3
Destination/Mask Proto Pre Cost Flags NextHop Interface
10.2.1.0/24 Direct 0 0 D 10.2.1.2 Gigabitethernet0/0/2.1

10.4.1.0/24 IBGP 255 0 RD 3.3.3.3 Vlanif30
同一 VPN 的 CE 能够相互 Ping 通，不同 VPN 的 CE 不能相互 Ping 通。
例如： CE1 能够 Ping 通 CE3 （ 10.3.1.1 ），但不能 Ping 通 CE4 （ 10.4.1.1 ）。
