1  简介

本文介绍了通过MPLS L3VPN技术提供VPN服务的典型配置举例。

2  配置前提

本文档中的配置均是在实验室环境下进行的配置和验证,配置前设备的所有参数均采用出厂时的缺省配置。如果您已经对设备进行了配置,为了保证配置效果,请确认现有配置和以下举例中的配置不冲突。

本文档假设您已了解MPLS L3VPN特性。

3  配置举例

3.1  组网需求

图1所示,Customer A和Customer B分别有位于两地的分支机构,现要求通过MPLS L3VPN技术,实现用户分支机构间路由信息的正常交互,且用户数据可以通过VPN方式在各站点间安全传输,不会发送至私网IP地址相同的其它用户站点中。

图1 MPLS L3VPN基本组网图

  

 

3.2  配置思路

·     为了使报文能够通过MPLS网络传输,需要在MPLS骨干网络中配置IGP路由协议,并利用LDP分发公网标签,作为VPN报文的外层标签。

·     为区分不同用户的路由信息,需要在PE上分别创建两个VPN实例,并为VPN实例配置RD和RT,在各实例内通过BGP分别引入不同用户的私网路由。

·     在PE设备之间配置MP-BGP协议并建立对等体,用于传输VPN的私网路由信息并分发内层标签,即私网标签。

3.3  使用版本

本举例是在S12500-S-CMW710-R7150P02版本上进行配置和验证的。

3.4  配置注意事项

由于在配置接口与VPN实例绑定后,接口上的IP地址等配置会清除,因此先配置接口与VPN实例的绑定关系,再进行其他配置。

3.5  配置步骤

1. 在MPLS骨干网上配置IGP协议(本例为OSPF协议),实现骨干网PE和P的互通

(1)     配置PE 1

# 配置骨干网接口以及环回口地址。

<PE1> system-view

[PE1] interface loopback 0

[PE1-LoopBack0] ip address 1.1.1.9 32

[PE1-LoopBack0] quit

[PE1] vlan 2

[PE1-vlan2] port ten-gigabitethernet 1/0/2

[PE1-vlan2] quit

[PE1] interface vlan-interface 2

[PE1-Vlan-interface2] ip address 10.1.1.1 24

[PE1-Vlan-interface2] quit

# 配置OSPF协议发布骨干网侧路由。

[PE1] ospf

[PE1-ospf-1] area 0

[PE1-ospf-1-area-0.0.0.0] network 10.1.1.0 0.0.0.255

[PE1-ospf-1-area-0.0.0.0] network 1.1.1.9 0.0.0.0

[PE1-ospf-1-area-0.0.0.0] quit

[PE1-ospf-1] quit

(2)     配置P

# 配置骨干网接口以及环回口地址。

<P> system-view

[P] interface loopback 0

[P-LoopBack0] ip address 2.2.2.9 32

[P-LoopBack0] quit

[P] vlan 2

[P-vlan2] port ten-gigabitethernet 1/0/2

[P-vlan2] quit

[P] vlan 5

[P-vlan5] port ten-gigabitethernet 1/0/3

[P-vlan5] quit

[P] interface vlan-interface 2

[P-Vlan-interface2] ip address 10.1.1.2 24

[P-Vlan-interface2] quit

[P] interface vlan-interface 5

[P-Vlan-interface5] ip address 10.1.4.1 24

[P-Vlan-interface5] quit

# 配置OSPF协议发布骨干网侧路由。

[P] ospf

[P-ospf-1] area 0

[P-ospf-1-area-0.0.0.0] network 10.1.1.0 0.0.0.255

[P-ospf-1-area-0.0.0.0] network 10.1.4.0 0.0.0.255

[P-ospf-1-area-0.0.0.0] network 2.2.2.9 0.0.0.0

[P-ospf-1-area-0.0.0.0] quit

[P-ospf-1] quit

(3)      配置PE 2

# 配置骨干网接口以及环回口地址。

<PE2> system-view

[PE2] interface loopback 0

[PE2-LoopBack0] ip address 3.3.3.9 32

[PE2-LoopBack0] quit

[PE2] vlan 5

[PE2-vlan5] port ten-gigabitethernet 1/0/1

[PE2-vlan5] quit

[PE2] interface vlan-interface 5

[PE2-Vlan-interface5] ip address 10.1.4.2 24

[PE2-Vlan-interface5] quit

# 配置OSPF协议发布骨干网侧路由。

[PE2] ospf

[PE2-ospf-1] area 0

[PE2-ospf-1-area-0.0.0.0] network 10.1.4.0 0.0.0.255

[PE2-ospf-1-area-0.0.0.0] network 3.3.3.9 0.0.0.0

[PE2-ospf-1-area-0.0.0.0] quit

[PE2-ospf-1] quit

配置完成后,PE 1、P、PE 2之间应能建立OSPF邻居,执行display ospf peer命令可以看到邻居达到Full状态。执行display ip routing-table命令可以看到PE之间学习到对方的Loopback路由。

以PE 1为例:

[PE1] display ospf peer verbose

 

          OSPF Process 1 with Router ID 1.1.1.9

                  Neighbors

 

 Area 0.0.0.0 interface 10.1.1.1(Vlan-interface2)'s neighbors

10.1.1.0/24         OSPF   10   1            10.1.1.1        Vlan2

2. 在MPLS骨干网上配置MPLS基本能力和MPLS LDP,建立LDP LSP

(1)     配置PE 1

[PE1] mpls lsr-id 1.1.1.9

[PE1] mpls ldp

[PE1-ldp] quit

[PE1] interface vlan-interface 2

[PE1-Vlan-interface2] mpls enable

[PE1-Vlan-interface2] mpls ldp enable

[PE1-Vlan-interface2] quit

(2)     配置P

[P] mpls lsr-id 2.2.2.9

[P] mpls ldp

[P-ldp] quit

[P] interface vlan-interface 2

[P-Vlan-interface2] mpls enable

[P-Vlan-interface2] mpls ldp enable

[P-Vlan-interface2] quit

[P] interface vlan-interface 5

[P-Vlan-interface5] mpls enable

[P-Vlan-interface5] mpls ldp enable

[P-Vlan-interface5] quit

(3)     配置PE 2

[PE2] mpls lsr-id 3.3.3.9

[PE2] mpls ldp

[PE2-ldp] quit

[PE2] interface vlan-interface 5

[PE2-Vlan-interface5] mpls enable

[PE2-Vlan-interface5] mpls ldp enable

[PE2-Vlan-interface5] quit

上述配置完成后,PE 1PPE 2之间应能建立LDP会话,执行display mpls ldp peer命令可以看到LDP会话的状态为Operational。执行display mpls ldp lsp命令,可以看到LDP LSP的建立情况。

以PE 1为例:

[PE1] display mpls ldp peer

Total number of peers: 1

Peer LDP ID             State         Role     GR   MD5  KA Sent/Rcvd

2.2.2.9:0               Operational   Passive  Off  Off  5/5

[PE1] display mpls ldp lsp

FECs: 4            Ingress: 1          Transit: 1      Egress: 3

 

FEC                In/Out Label        Nexthop         OutInterface

1.1.1.9/32         3/-

                   -/1151(L)

2.2.2.9/32         -/3                 10.1.1.2        Vlan2

                   1151/3              10.1.1.2        Vlan2

3.3.3.9/32         -/1150              10.1.1.2        Vlan2

                   1150/1150           10.1.1.2        Vlan2

3. 在PE设备上配置VPN实例,将CE接入PE

(1)     配置PE 1

# 为该实例配置RD为100:1,用于形成VPNv4路由,以便区分不同用户相同网段的路由。

[PE1-vpn-instance-customerA] route-distinguisher 100:1

# 为该VPN实例配置VPN Target属性,其中接收路由的属性为111:1,发布路由的属性为222:1。(此处为表示接收和发送属性的含义,取值有所不同,为便于管理,用户可以将接收和发送的属性配置为相同的值)

[PE1-vpn-instance-customerA] vpn-target 111:1 import-extcommunity

[PE1-vpn-instance-customerA] vpn-target 222:1 export-extcommunity

[PE1-vpn-instance-customerA] quit

[PE1] ip vpn-instance customerB

[PE1-vpn-instance-customerB] route-distinguisher 200:1

[PE1-vpn-instance-customerB] vpn-target 333:1 import-extcommunity

[PE1-vpn-instance-customerB] vpn-target 444:1 export-extcommunity

[PE1-vpn-instance-customerB] quit

# 配置Vlan-interface100与VPN实例customerA进行绑定。

[PE1] vlan 100

[PE1-vlan100] port ten-gigabitethernet 1/0/1

[PE1-vlan100] quit

[PE1] interface vlan-interface 100

[PE1-Vlan-interface100] ip binding vpn-instance customerA

[PE1-Vlan-interface200] ip address 200.1.1.2 24

[PE1-Vlan-interface200] quit

(2)     配置PE 2

# PE 2上为Customer A创建VPN实例,名为“customerA”。

[PE2] ip vpn-instance customerA

# 为该VPN实例配置RD,为便于识别,建议与PE 1上为该实例配置的RD保持一致。

[PE2-vpn-instance-customerA] route-distinguisher 100:1

# 为该VPN实例配置VPN Target,需要注意的是接收和发送的属性要分别与PE 1上配置的发送和接收的属性保持一致。

[PE2-vpn-instance-customerA] vpn-target 222:1 import-extcommunity

[PE2-vpn-instance-customerA] vpn-target 111:1 export-extcommunity

[PE2-vpn-instance-customerA] quit

# 按同样方式配置VPN实例“customerB”,并配置相应的RD和VPN Target。

[PE2] ip vpn-instance customerB

[PE2-vpn-instance-customerB] route-distinguisher 200:1

[PE2-vpn-instance-customerB] vpn-target 444:1 import-extcommunity

[PE2-vpn-instance-customerB] vpn-target 333:1 export-extcommunity

[PE2-vpn-instance-customerB] quit

# 分别将Vlan-interface101和Vlan-interface202与customerA和customerB实例进行绑定。

[PE2] vlan 101

[PE2-vlan101] port ten-gigabitethernet 1/0/2

[PE2-vlan101] quit

[PE2] interface vlan-interface 101

[PE2-Vlan-interface101] ip binding vpn-instance customerA

[PE2-Vlan-interface202] quit

(3)     配置CE

图1配置各CE的接口IP地址,配置过程略。

配置完成后,在PE设备上执行display ip vpn-instance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。

以PE 1和CE 1为例:

[PE1] display ip vpn-instance

  Total VPN-Instances configured : 2

  VPN-Instance Name               RD                     Create time

  customerA                       100:1                  2014/03/22 13:20:08

3.6  验证配置

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PE 1上的customerA为例:

[PE1] display ip routing-table vpn-instance customerA

 

Destinations : 13        Routes : 13

 

Destination/Mask    Proto  Pre  Cost         NextHop         Interface

0.0.0.0/32          Direct 0    0            127.0.0.1       InLoop0
