测试结果：

PE1：

1)Remote LDP的状态信息:

[S5560]display l2vpn ldp

Total number of LDP PWs: 1, 1 up, 0 down

Peer            PW ID/VPLS ID         In/Out Label    State Owner

192.168.30.1    3                     65662/1025      Up    vpna

2)查看LDP状态

[S5560]display mpls ldp peer

Total number of peers: 1

Peer LDP ID             State         Role     GR   MD5  KA Sent/Rcvd

PW封装模式需要与对端PE保持一致，本例中使用的是Ethernet。

PW state 是UP表示该PW已正常建立

总结：

1、 两端PE的PW模式需要保持一致

2、 V5设备中的vc id与V7设备中的pw id要相同。

3、 一个PW只能对应一个AC接口。

4、查看PW状态前，需要保持AC口的状态是UP，否则即使配置正确，PW的状态也会是down
