简介

本文档介绍如何对Cisco IOS® XE的PMIPv6技术进行故障排除。

先决条件

要求

Cisco 建议您了解以下主题：

使用的组件

本文档中的信息基于Cisco IOS XE软件。

本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您的网络处于活动状态，请确保您了解所有命令的潜在影响。

背景信息

对移动IP技术进行故障排除时，主要考虑的是蜂窝网接口和无线网络控制器(RNC)之间是否具有良好信号。您的Internet服务提供商(ISP)提供用于在移动接入网关(MAG)和本地移动锚点(LMA)之间建立隧道的IP地址。

MAG不会建立指向LMA的PMIPv6隧道。

本部分提供在MAG上创建Tunnel0的常见问题的解决方案。我们以下面的网络图为例。

Baseline topology

在此图中，MAG无法建立通向LMA的Tunnel0。

 MAG#show ip interface brief | exclude unassigned
Interface              IP-Address      OK? Method Status                Protocol
Cellular0/1/0          203.0.113.1     YES NVRAM  up                    up      
Ethernet0/1            198.51.100.254  YES NVRAM  up                    up

诊断问题

检查移动接入网关(MAG)上的配置并验证ISP提供的信息是否正确：

APN =定义与本地IP核心数据包网络的数据连接，以实现蜂窝连接
NAI =从MAG到ISP的网络ID
LMA的IP地址=本地ISP提供的IP地址

此信息可在蜂窝网接口上找到。

2.验证MAG的状态。INIT状态表示MAG尝试连接到LMA。

 a) non-working example

 MAG#show ipv6 mobile pmipv6 mag binding

	[Binding][MN]: HNP: 0
	[Binding][MN]: APN: 13511.mcs
	[Binding][MN][LMA]: Id: LMA_SVC

		[Binding][MN][PATH][GREKEY]: Upstream: 0, Downstream: 0
----------------------------------------

3.验证路由器上的MAG状态。感兴趣的消息是PBU和PBA，它们是从MAG到LMA绑定的请求和应答。

MAG#show ipv6 mobile pmipv6 mag stats

4.验证蜂窝网接口是否有通向ISP的良好信号。

备注：蜂窝网故障排除超出本文档的范围。

5.在平台上启用调试，以验证MAG和LMA之间的报文交换。

要考虑的重要日志：

A)MAG启动与LMA的连接。

*4月14日20:53:33.397: [PMIPV6_MAG_EVENT]：事件已收到为Nai附加的新MN intf:310410901877700@13511.mcs位于路径状态机中，路径：Cellular0/1/0，状态：PATH_NULL，新状态：PATH_INIT

B)发送到LMA以建立隧道0的PBU消息

*4月14日20:53:33.398: [PMIPV6_MAG_EVENT]：发送至Nai的PBU消息：310410901877700@13511.mcs

C)MAG未收到来自LMA的确认(PBA)。MAG尝试发送另一个PBU以建立隧道。

*4月14日20:53:34.423: [PMIPV6_MAG_EVENT]：接收到PBU的Retx计时器已过期Nai:310410901877700@13511.mcs在路径状态机中，路径：Cellular0/1/0，状态：PATH_INIT，新状态：PATH_INIT

6.继续嵌入式数据包捕获(EPC)，验证LMA未发送PBA数据包。嵌入式数据包捕获配置指南。

数据包捕获显示IP地址203.0.113.2（由ISP分配的地址）将PBU数据包发送到LMA IP地址203.0.113.10。

有关详细信息，可使用命令monitor capture cap export bootflash:<name>.pcap将捕获导出到bootflash并以.pcap文件的形式上传到tftp服务器。

在导出的捕获中，MAG向LMA请求确认，但LMA不发送PBA数据包。

PMIPv6 Tunnel Not Established

7.此问题与ISP无关。联系您当地的ISP，询问是否启用了PMIP服务。

MAG未建立指向LMA的PMIPv6隧道（PBU和PBA数据包交换）。

诊断问题

1.检查移动接入网关(MAG)上的配置。

2.检查MAG和LMA之间的关联。

MAG#sh ipv6 mobile pmipv6 mag binding 
MAG#

3.验证PBU和PBA消息。

 MAG#show ipv6 mobile pmipv6 mag stats

A)RESP to MCSA CREATE REQ表示MAG请求连接到LMA。当LMA拒绝PBU时，MAG以清除指示消息开始。

4.启用debug ipv6 mobile mag events以验证MAG上显示的错误代码。

5.继续捕获路由器上的控制平面，并验证确认数据包中的移动IPv6报头。

比较捕获

报头有错误

PMIPv6 Tunnel Not Established [Error]

信头无错误

PMIPv6 Tunnel Established

6.与您的本地ISP进行验证。在这种情况下，为了建立反向隧道，LMA应答不包含主地址。

1.验证天线是否具有良好信号。

备注：蜂窝网故障排除超出本文档的范围。

2.激活debug ipv6 mobile以验证设备是否将PBU数据包发送到LMA。

At this point the MAG waits for a reply from the LMA to establish the tunnel. Since the timer expires, the MAG clears the entry and starts the process.

要考虑的重要日志：

A)MAG使与LMA的连接到期并等待响应。

*5月9日20:28:26.784: [PMIPV6_LMN_EVENT]：连接计时器已过期
*5月9日20:28:26.784: [PMIPV6_LMN_EVENT]：事件已接收附加计时器过期状态：LMN_READY，新状态：LMN_READY

*5月9日20:28:26.784: [PMIPV6_MAG_EVENT]：事件已收到为Nai附加的旧MNintf:310410901877700@13511.mcs（路径状态机），路径：Cellular0/1/0，状态：PATH_INIT，新状态：PATH_INIT

B)系统会发送一条清除消息，以删除之前的绑定并建立新的隧道。

*5月9日20:28:39.523: [PMIPV6_MAG_EVENT]：事件接收到Nai的最后路径关闭：310410901877700@13511.mcs处于状态：INIT，新状态：NULL

    *5月9日20:28:39.523: [PMIPV6_MAG_EVENT]：正在发送清理查找原因上次路径关闭，原始事件ReTx计时器已用尽
    *5月9日20:28:39.523: [PMIPV6_LMN_EVENT]：事件从MAG接收清理请求，状态为：LMN_READY，新状态：LMN_READY

    *5月9日20:28:39.523: [PMIPV6_MAG_EVENT]:Nai:310410901877700@13511.mcs，已删除绑定

C)PBU消息发送到LMA以建立新的隧道0。一旦MAG收到，PBA就会启动隧道。

*5月9日20:28:41.955:[PMIPV6_MAG_EVENT]:PBU消息发送至Nai:310410901877700@13511.mcs

D)MAG和LMA接收并接受PBA。

    *5月9日20:28:45.228: [PMIPV6_MAG_EVENT]：已接收消息：PBA
    *5月9日20:28:45.228: [PMIPV6_MAG_EVENT]:PBA:nai(310410901877700@13511.mcs),nai len:26,lli(310410901877700@135),ll len:21,att:4,lifetime:3600,status:0
    *5月9日20:28:45.228: [PMIPV6_MAG_EVENT]：路径状态机中的Nai收到事件的PBA接受：310410901877700@13511.mcs，路径：Cellular0/1/0，状态：PATH_INIT，新状态：PATH_ACTIVE

E)隧道0已建立。

   *5月9日20:28:45.229: [PMIPV6_LMN_EVENT]：为Tunnel0接收地址更改事件
   *5月9日20:28:45.229: %LINEPROTO-5-UPDOWN：接口Tunnel0上的线路协议，状态更改为up
   *5月9日20:28:45.230: %PMIPV6-5-TUNNELUP：启用代理移动IPv6隧道Tunnel0

3.继续捕获路由器上的控制平面，并验证数据包是否在MAG和LMA之间共享。

PMIPv6 Tunnel Intermittent Connection

在导出的捕获中，MAG请求确认LMA。LMA回复此消息；但是，由于传输出现问题，MAG不会一致地接收这些消息。
一旦传输稳定，隧道就会变得稳定。

4.与您的本地ISP验证这两台设备之间的传输是否稳定。

其他信息

PMIP预计不会从ISP收到默认路由。为了获得连接和建立隧道，需要有一条指向LMA的IP的主机路由，并将蜂窝接口添加为下一跳。

示例：
ip route 203.0.113.10 255.255.255 cellular0/1/0

术语	描述
国际移动用户身份(IMSI)	为SIM卡分配的15位数字代码编号
国际移动设备标识(IMEI)	分配给移动设备的15位代码
集成电路卡标识符(ICCID)	为硬件SIM卡指定了19到20位代码
移动站国际用户目录号码(MSISDN)	ISP分配的移动设备编号。这包括国家/地区代码和分配的编号。
网络访问标识符(NAI)	网络访问身份验证期间客户端提交的用户身份
接入点名称(APN)	与移动网络数据连接的移动设备的信息（漫游过程）
移动节点(MN)	参与任何与IP移动性相关的PMIP所需的IP主机或路由器
移动接入网关(MAG)	管理与ISP连接的接入设备
本地移动锚点(LMA)	代理移动IPv6域(PMIP)中移动节点的家乡代理
家庭地址(HoA)	LMA池分配的动态IP地址
代理绑定更新(PBU)	来自MAG的请求，以建立LMA之间的隧道。此请求包括移动节点标识符选项。
代理绑定确认(PBA)	从LMA发送到MAG的消息，其中包括HoA网络前缀并触发建立双向隧道
