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
- 配置CE上接入PE的接口的IP地址
配置CE1。
CE1:
interface Ethernet1/0/0
ip address 10.1.1.1 255.255.255.252
ip address 10.1.2.1 255.255.255.252 sub
配置CE2。
CE2:
interface Ethernet1/0/1
ip address 10.1.1.2 255.255.255.252
interface Ethernet1/0/0
ip address 10.1.2.2 255.255.255.252
- 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 LoopBack1
ip address 1.1.1.1 255.255.255.255
interface Ethernet1/0/1
ip address 10.2.1.1 255.255.255.252

network 1.1.1.1 0.0.0.0
network 10.2.1.0 0.0.0.3
network 10.4.1.0 0.0.0.3
配置P1。
P1:
interface LoopBack1
ip address 2.2.2.2 255.255.255.255
interface Ethernet1/0/0
ip address 10.3.1.1 255.255.255.252
interface Ethernet1/0/1
ip address 10.2.1.2 255.255.255.252
ospf 1

network 2.2.2.2 0.0.0.0
network 10.2.1.0 0.0.0.3
network 10.3.1.0 0.0.0.3
配置P2。
P2:
interface LoopBack1
ip address 3.3.3.3 255.255.255.255
interface Ethernet1/0/0
ip address 10.5.1.1 255.255.255.252
interface Ethernet1/0/1
ip address 10.4.1.2 255.255.255.252
ospf 1

network 3.3.3.3 0.0.0.0
network 10.4.1.0 0.0.0.3
network 10.5.1.0 0.0.0.3
配置PE2。
PE2:
interface LoopBack1
ip address 4.4.4.4 255.255.255.255
interface Ethernet1/0/0
ip address 10.3.1.2 255.255.255.252
ospf 1
area 0.0.0.0
network 4.4.4.4 0.0.0.0
network 10.3.1.0 0.0.0.3
配置PE3。
PE3:
interface LoopBack1
ip address 5.5.5.5 255.255.255.255
interface Ethernet1/0/1
ip address 10.5.1.2 255.255.255.252
ospf 1
area 0.0.0.0
network 5.5.5.5 0.0.0.0
network 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：
[~PE1]dis ip routing-table
Route Flags: R - relay, D - download to fib, T - to vpn-instance, B - black hole

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

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 Network
Codes: LAM(Label Advertisement Mode), SsnAge Unit(DDDD:HH:MM)
An asterisk (*) before a session means the session is being deleted.

[~PE1]
- 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 4.4.4.4
remote-ip 4.4.4.4
mpls ldp remote-peer 5.5.5.5

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

在PE上再次执行命令display mpls l2vc interface查看PW的状态。可以看到主用PW的VC状态是down，BFD for PW是available，但BFD state为down。备用PW的VC状态是up，BFD for PW是available，且BFD state为up。
