MPLS动态LSP配置实验

在这里插入图片描述

基本配置

接口地址和OSPF配置，省略！全网互通！注意：8.8.8.8和9.9.9.9也要宣告！

查看LDP会话

基本信息查看

<ar1>dis mpls ldp session

 LDP Session(s) in Public Network
 Codes: LAM(Label Advertisement Mode), SsnAge Unit(DDDD:HH:MM)
 A '*' before a session means the session is being deleted.
 ------------------------------------------------------------------------------
 PeerID             Status      LAM  SsnRole  SsnAge      KASent/Rcv
 ------------------------------------------------------------------------------

#注释：
PeerID：是邻居的ID
Operational：状态，配置成功的标志Operational状态
Passive：说明是被动，主动是Active
