目标

静态BFD检测PW，配置比较简单，报文交互比较少。

组网需求

在MPLS L2VPN组网方案中：

PE1和PE2之间建立PW1（主）。

PE1和PE3之间建立PW2（备）。

如图1，要求使用BFD检测主备PW的连通性，当主PW出现故障以后，能够在50ms内将业务切换到备用PW上。

配置思路

• 配置MPLS网络。

• 在PE1的AC接口配置PW1（PE1到PE2）、PW2（PE1到PE3），形成主备PW关系。

• 配置BFD会话检测PW1和PW2。

操作步骤

1. 配置CE上接入PE的接口的IP地址

配置CE1。

CE1:
interface Ethernet1/0/0ip address 10.1.1.1 255.255.255.252ip address 10.1.2.1 255.255.255.252 sub

配置CE2。

CE2:
interface Ethernet1/0/1ip address 10.1.1.2 255.255.255.252
interface Ethernet1/0/0ip address 10.1.2.2 255.255.255.252

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。

PE1:
interface LoopBack1ip address 1.1.1.1 255.255.255.255
interface Ethernet1/0/1ip address 10.2.1.1 255.255.255.252

配置P1。

P1:
interface LoopBack1ip address 2.2.2.2 255.255.255.255
interface Ethernet1/0/0ip address 10.3.1.1 255.255.255.252
interface Ethernet1/0/1ip address 10.2.1.2 255.255.255.252

配置P2。

P2:
interface LoopBack1ip address 3.3.3.3 255.255.255.255
interface Ethernet1/0/0ip address 10.5.1.1 255.255.255.252

ospf 1area 0.0.0.0network 3.3.3.3 0.0.0.0network 10.4.1.0 0.0.0.3network 10.5.1.0 0.0.0.3

配置PE2。

PE2:
interface LoopBack1ip address 4.4.4.4 255.255.255.255
interface Ethernet1/0/0ip address 10.3.1.2 255.255.255.252
ospf 1area 0.0.0.0network 4.4.4.4 0.0.0.0network 10.3.1.0 0.0.0.3

配置PE3。

PE3:
interface LoopBack1ip address 5.5.5.5 255.255.255.255
interface Ethernet1/0/1ip address 10.5.1.2 255.255.255.252
ospf 1area 0.0.0.0network 5.5.5.5 0.0.0.0network 10.5.1.0 0.0.0.3

配置完成后，在PE上执行display ip routing-table命令，可以看到PE1与PE2之间、PE1与PE3之间互相学到到对方Loopback1接口的路由。

以PE1的显示为例：

1. 在MPLS骨干网上配置MPLS基本能力

使能MPLS，指定LSR-ID为Loopback1接口的IP地址。在骨干网接口上使能MPLS和MPLS LDP。

配置PE1。

PE1:
mpls lsr-id 1.1.1.1
mpls
mpls ldp
interface Ethernet1/0/1mplsmpls ldp
interface Ethernet1/0/2mplsmpls ldp

配置PE1。

P1:
mpls lsr-id 2.2.2.2
mpls
mpls ldp
interface Ethernet1/0/1mplsmpls ldp
interface Ethernet1/0/0mplsmpls ldp

配置P2。

P2:
mpls lsr-id 3.3.3.3
mpls
mpls ldp
interface Ethernet1/0/1mplsmpls ldp
interface Ethernet1/0/0mplsmpls ldp

配置PE2。

PE2:
mpls lsr-id 4.4.4.4
mpls
mpls ldp
interface Ethernet1/0/0mplsmpls ldp

配置PE3。

PE3:
mpls lsr-id 5.5.5.5
mpls
mpls ldp
interface Ethernet1/0/1mplsmpls ldp

上述配置完成后，在PE上执行display tunnel-info all命令，PE1与PE2之间、PE1与PE3之间存在MPLS LSP隧道。

以PE1的显示为例。

[~PE1]DIS tunnel-info all
Tunnel ID            Type                Destination                            Status

[~PE1]
[~PE1]

在PE上执行display mpls ldp session命令可以看到PE与相邻P的LDP对等体关系的Status为“Operational”。

以PE1的显示为例：

[~PE1]dis mpls ldp session LDP Session(s) in Public NetworkCodes: 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--------------------------------------------------------------------------2.2.2.2:0          Operational DU   Passive  0000:00:08   34/343.3.3.3:0          Operational DU   Passive  0000:00:06   27/27--------------------------------------------------------------------------TOTAL: 2 Session(s) Found.
[~PE1] 

1. 在PE之间建立远端LDP会话

在配置远端LDP会话，指定的IP地址通常为LDP远端对等体的Loopback接口地址。

配置PE1。

PE1:
mpls ldp remote-peer 4.4.4.4remote-ip 4.4.4.4
mpls ldp remote-peer 5.5.5.5remote-ip 5.5.5.5

配置PE2。

PE2:
mpls ldp remote-peer 1.1.1.1remote-ip 1.1.1.1

配置PE3。

PE3:
mpls ldp remote-peer 1.1.1.1remote-ip 1.1.1.1

配置完成后，在PE上执行display mpls ldp session命令可以看到PE之间的远端LDP对等体关系的Status为“Operational”，即远端对等体关系已建立。

以PE1的显示为例：

[~PE1-mpls-ldp-remote-5.5.5.5]DIS MPLS LDP session LDP Session(s) in Public NetworkCodes: 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--------------------------------------------------------------------------2.2.2.2:0          Operational DU   Passive  0000:00:11   46/463.3.3.3:0          Operational DU   Passive  0000:00:09   39/394.4.4.4:0          Operational DU   Passive  0000:00:01   6/65.5.5.5:0          Operational DU   Passive  0000:00:00   4/4--------------------------------------------------------------------------TOTAL: 4 Session(s) Found.

1. 在PE上使用PW模板配置PW

配置PE1。

PE1:
mpls l2vpn
pw-template 1to2  peer-address 4.4.4.4 control-word 
pw-template 1to3  peer-address 5.5.5.5 control-word 
interface Ethernet1/0/0mpls l2vc pw-template 1to2 100mpls l2vc pw-template 1to3 200 secondary

配置PE2。

PE2:
mpls l2vpn
pw-template 2to1  peer-address 1.1.1.1 control-word 
interface Ethernet1/0/1mpls l2vc pw-template 2to1 100

配置PE3。

PE3:
mpls l2vpn
pw-template 3to1  peer-address 1.1.1.1 control-word 
interface Ethernet1/0/0mpls l2vc pw-template 3to1 200

配置完成后，在PE上执行display pw-template命令可以看到PW模板的配置信息。

以PE1的显示为例。

[~PE1-Ethernet1/0/0]dis pw-template

在PE上查看L2VPN连接信息，执行display mpls l2vc interface命令可以看到PW建立成功，且为Active状态。并且主备PW都没有使能BFD for PW功能。

以PE1的显示为例。

1. 在PE之间配置静态BFD检测PW功能

配置PE1。

PE1:
bfd
bfd 1to2 bind pw interface Ethernet1/0/0discriminator local 12discriminator remote 21
bfd 1to3 bind pw interface Ethernet1/0/0 secondarydiscriminator local 13discriminator remote 31

配置PE2。

PE2:
bfd
bfd 2to1 bind pw interface Ethernet1/0/1discriminator local 21discriminator remote 12

配置PE3。

PE3:
bfd
bfd 3to1 bind pw interface Ethernet1/0/0discriminator local 31discriminator remote 13

配置完成后，PE1与PE2之间，PE1与PE3之间建立BFD会话。执行display bfd session all命令，可以看到State为Up。

以PE1的显示为例。

1. 验证配置结果

当主PW正常工作时，CE1的主地址可以Ping通CE2的10.1.1.2地址。备用PW不工作，CE1的从地址无法Ping通CE2的10.1.2.2地址。

在PE上执行命令display mpls l2vc interface查看PW的状态。可以看到主备PW都使能了BFD for PW功能，且BFD state为up。
