配置SVC方式的VPWS实例

操作步骤

1. 按图9-22配置CE、PE和P的各接口地址

   具体配置过程略。

2. 在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和PE2作为LSR ID的32位Loopback接口地址。

   具体配置过程略。

3. 在MPLS骨干网上配置MPLS基本能力和LDP，即，使用LDP LSP隧道

   # 配置PE1。

   [~PE1] mpls lsr-id 1.1.1.9

   [*PE1] mpls

   [*PE1-mpls] quit

   [*PE1] mpls ldp

   [*PE1-mpls-ldp] quit

   [*PE1] mpls ldp remote-peer 3.3.3.9

   [*PE1-mpls-ldp-remote-3.3.3.9] remote-peer 3.3.3.9

   [*PE1-mpls-ldp-remote-3.3.3.9] quit

   [*PE1] interface gigabitethernet 2/0/0

   [*PE1-GigabitEthernet2/0/0] mpls

   [*PE1-GigabitEthernet2/0/0] mpls ldp

   [*PE1-GigabitEthernet2/0/0] quit

   [*PE1] commit

   # 配置P。

   [~P] mpls lsr-id 2.2.2.9

   [*P] mpls

   [*P-mpls] quit

   [*P] mpls ldp

   [*P-mpls-ldp] quit

   [*P] interface gigabitethernet 1/0/0

   [*P-GigabitEthernet1/0/0] mpls

   [*P-GigabitEthernet1/0/0] mpls ldp

   [*P-GigabitEthernet1/0/0] quit

   [*P] interface gigabitethernet 2/0/0

   [*P-GigabitEthernet2/0/0] mpls

   [*P-GigabitEthernet2/0/0] mpls ldp

   [*P-GigabitEthernet2/0/0] quit

   [*P] commit

   # 配置PE2。

   [~PE2] mpls lsr-id 3.3.3.9

   [*PE2] mpls

   [*PE2-mpls] quit

   [*PE2] mpls ldp

   [*PE2-mpls-ldp] quit

   [*PE2] mpls ldp remote-peer 1.1.1.9

   [*PE2-mpls-ldp-remote-1.1.1.9] remote-peer 1.1.1.9

   [*PE2-mpls-ldp-remote-1.1.1.9] quit

   [*PE2] interface gigabitethernet 1/0/0

   [*PE2-GigabitEthernet1/0/0] mpls

   [*PE2-GigabitEthernet1/0/0] mpls ldp

   [*PE2-GigabitEthernet1/0/0] quit

   [*PE2] commit

   上述配置完成后，PE1、P、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Session State项为Operational。

   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)
    An asterisk (*) before a session means the session is being deleted.
    ------------------------------------------------------------------------------
    PeerID             Status      LAM  SsnRole  SsnAge      KASent/Rcv
    ------------------------------------------------------------------------------
    2.2.2.9:0          Operational DU   Passive  000:02:22   572/572
    3.3.3.9:0          Operational DU   Passive  000:02:21   566/566
    ------------------------------------------------------------------------------
    TOTAL: 2 session(s) Found.

4. 在PE上使能MPLS L2VPN，并创建静态VC连接

   # 配置PE1：在接入CE1的接口GE1/0/0上创建静态VC。

   [~PE1] mpls l2vpn

   [*PE1-l2vpn] quit

   [*PE1] interface gigabitethernet 1/0/0

   [*PE1-GigabitEthernet1/0/0] mpls static-l2vc destination 3.3.3.9 transmit-vpn-label 100 receive-vpn-label 200

   [*PE1-GigabitEthernet1/0/0] undo shutdown

   [*PE1-GigabitEthernet1/0/0] quit

   [*PE1] commit

   # 配置PE2：在接入CE2的接口GE2/0/0上创建静态VC。

   [~PE2] mpls l2vpn

   [*PE2-l2vpn] quit

   [*PE2] interface gigabitethernet 2/0/0

   [*PE2-GigabitEthernet2/0/0] mpls static-l2vc destination 1.1.1.9 transmit-vpn-label 200 receive-vpn-label 100

   [*PE2-GigabitEthernet2/0/0] undo shutdown

   [*PE2-GigabitEthernet2/0/0] quit

   [*PE2] commit

5. 验证配置结果

   在PE上查看SVC的L2VPN连接信息，可以看到建立了一条静态L2VC连接。

   以PE1的显示为例：

   <PE1> display mpls static-l2vc interface gigabitethernet 1/0/0

    *Client Interface   : GigabitEthernet1/0/0 is up

     AC Status          : up

     VC State           : up

     VC ID              : 0

     VC Type            : Ethernet

     Destination        : 3.3.3.9

     Transmit VC Label  : 100

     Receive VC Label   : 200

     Label Status       : 0

     Token Status       : 0

     Control Word       : Disable

     VCCV Capability    : alert lsp-ping bfd

     active state       : active

     OAM Protocol       : --

     OAM Status         : --

     OAM Fault Type     : --

     PW APS ID          : --

     PW APS Status      : --

     TTL Value          : 1

     Link State         : up

     Tunnel Policy      : --

     PW Template Name   : --

     Traffic Behavior   : --

     Main or Secondary  : Main

     VC tunnel/token info : 1 tunnels/tokens

     NO.0  TNL Type : lsp   , TNL ID : 0x2002002

     Create time          : 0 days, 0 hours, 8 minutes, 2 seconds

     UP time              : 0 days, 0 hours, 6 minutes, 12 seconds

     Last change time     : 0 days, 0 hours, 6 minutes, 12 seconds

     VC last up time : 2008-07-24 12:31:31
     VC total up time: 0 days, 2 hours, 12 minutes, 51 seconds

     CKey                 : 17                                                     
     NKey                 : 18   

   执行命令display l2vpn ccc-interface vc-type static-vc up，可以看到VC Type为static-vc，状态为up。以PE1的显示为例：

   <PE1> display l2vpn ccc-interface vc-type static-vc up

   Total ccc-interface of SVC VC: 1

   up (1), down (0)

   Interface                     Encap Type               State     VC Type

   GigabitEthernet1/0/0                      ethernet                      up          static-vc

   CE1和CE2能够相互Ping通。
