排除IOS XE路由器上的PMIP隧道建立故障
簡介
本文檔介紹如何對Cisco IOS® XE的PMIPv6技術進行故障排除。
必要條件
需求
思科建議您瞭解以下主題：
採用元件
本檔案中的資訊是根據Cisco IOS XE軟體。
本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路運作中，請確保您瞭解任何指令可能造成的影響。
背景資訊
當您對移動IP技術進行故障排除時，主要考慮事項是在蜂窩介面和無線網路控制器(RNC)之間有一個良好的訊號。您的Internet服務提供商(ISP)提供您用來在移動接入網關(MAG)和本地移動錨點(LMA)之間建立隧道的IP地址。
MAG不會建立指向LMA的PMIPv6隧道。
本節提供了在MAG上建立Tunnel0這一常見問題的解決方案。以下網路圖為例。
在此圖中，MAG無法建立通向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
診斷問題
- 檢視移動接入網關(MAG)上的配置並驗證ISP提供的資訊是否正確：
- APN =定義與本地IP核心資料包網路的資料連線，用於蜂窩連線
- NAI =從MAG到ISP的網路ID
- LMA的IP地址=本地ISP提供的IP地址
此資訊可在手機介面上找到。

2.驗證MAG的狀態。INIT狀態指示MAG嘗試連線到LMA。
a) non-working example
MAG#show ipv6 mobile pmipv6 mag binding Total number of bindings: 1 ---------------------------------------- [Binding][MN]: Domain: LMA-DOMAIN, Nai: 310410901877700@13511.mcs [Binding][MN]: State: INIT [Binding][MN]: Interface: Loopback0 [Binding][MN]: Hoa: 0.0.0.0, Att: 4, llid: 310410901877700@135 [Binding][MN]: HNP: 0 [Binding][MN]: APN: 13511.mcs [Binding][MN][LMA]: Id: LMA_SVC [Binding][MN][LMA]: Lifetime: 0 [Binding][MN]: Yes [Binding][MN][Mobile Network]: Ethernet0/1 [Binding][MN][PATH]: interface: Cellular0/1/0, Label: MAG State: PATH_INIT Refresh time: 0(sec), Refresh time Remaining: 0(sec) ----------------------------------------
b) working example
MAG#show ipv6 mobile pmipv6 mag binding Total number of bindings: 1 ---------------------------------------- [Binding][MN]: Domain: LMA-DOMAIN, Nai: 310410901877700@13511.mcs [Binding][MN]: State: ACTIVE [Binding][MN]: Interface: Loopback0 [Binding][MN]: Hoa: x.x.x.x, Att: 4, llid: 310410901877700@135 [Binding][MN]: HNP: 0 [Binding][MN]: APN: 13511.mcs [Binding][MN][LMA]: Id: LMA_SVC [Binding][MN][LMA]: Lifetime: 3600 [Binding][MN]: Yes [Binding][MN][Mobile Network]: Ethernet0/1 [Binding][MN][PATH]: interface: Cellular0/1/0, Label: MAG State: PATH_ACTIVE Tunnel: Tunnel0 Refresh time: 300(sec), Refresh time Remaining: 299(sec) [Binding][MN][PATH][GREKEY]: Upstream: 0, Downstream: 0 ----------------------------------------
3.驗證路由器上的MAG狀態。感興趣的報文是PBU和PBA，它們是請求和回覆MAG與LMA的繫結。
MAG#show ipv6 mobile pmipv6 mag stats ---------------------------------------- [MAG819]: Total Bindings : 1 [MAG819]: PBU Sent : 6 [MAG819]: PBA Rcvd : 0 [MAG819]: PBRI Sent : 0 [MAG819]: PBRI Rcvd : 0 [MAG819]: PBRA Sent : 0 [MAG819]: PBRA Rcvd : 0 [MAG819]: No Of handoff : 0 Detailed Statistics Information < snip >
4.驗證蜂窩介面是否有向ISP發出的良好訊號。
附註：手機網路故障排除超出本文檔的範圍。
5.啟用平台上的調試，以驗證MAG和LMA之間的報文交換。

要考慮的重要日誌：
A)MAG啟動與LMA的連線。
*4月14日20:53:33.397: [PMIPV6_MAG_EVENT]：事件已收到為Nai附加的新MNintf：路徑狀態機中的310410901877700@13511.mcs，路徑：Cellular0/1/0，狀態：PATH_NULL，新狀態：PATH_INIT
B)傳送到LMA以建立隧道0的PBU消息
*4月14日20:53:33.398: [PMIPV6_MAG_EVENT]：向Nai傳送的PBU消息：310410901877700@13511.mcs
C)MAG未收到來自LMA的確認(PBA)。MAG嘗試傳送另一個PBU以建立隧道。
*4月14日20:53:34.423: [PMIPV6_MAG_EVENT]：收到事件的PBU恢復計時器對於Nai已過期：310410901877700@13511.mcs在路徑狀態機器中，路徑：Cellular0/1/0，狀態：PATH_INIT，新狀態：PATH_INIT
6.繼續使用嵌入式資料包捕獲(EPC)，驗證LMA沒有傳送PBA資料包。嵌入式資料包捕獲配置指南。
MAG#monitor capture cap control-plane both access-list tac buffer size 10 MAG#monitor capture cap start
< wait at least 3 minutes >
MAG#show monitor capture cap buffer brief ---------------------------------------------------------------------------- # size timestamp source destination dscp protocol ---------------------------------------------------------------------------- 0 194 0.000000 203.0.113.2 -> 203.0.113.10 0 BE UDP 1 194 1.024000 203.0.113.2 -> 203.0.113.10 0 BE UDP 2 194 3.075008 203.0.113.2 -> 203.0.113.10 0 BE UDP 3 194 7.109994 203.0.113.2 -> 203.0.113.10 0 BE UDP 4 194 15.178991 203.0.113.2 -> 203.0.113.10 0 BE UDP 5 194 31.246041 203.0.113.2 -> 203.0.113.10 0 BE UDP 6 194 65.757016 203.0.113.2 -> 203.0.113.10 0 BE UDP 7 194 66.780010 203.0.113.2 -> 203.0.113.10 0 BE UDP 8 194 68.828011 203.0.113.2 -> 203.0.113.10 0 BE UDP 9 194 72.861014 203.0.113.2 -> 203.0.113.10 0 BE UDP 10 194 80.931003 203.0.113.2 -> 203.0.113.10 0 BE UDP
資料包捕獲顯示IP地址203.0.113.2（由ISP分配的地址）將PBU資料包傳送到LMA IP地址203.0.113.10。
如需更多詳細資訊，可以使用monitor capture cap export bootflash:<name>.pcap 指令將擷取匯出至bootflash，並以.pcap檔案上傳到tftp伺服器。
在匯出的捕獲中，MAG向LMA請求確認，但LMA不傳送PBA資料包。
7.此問題與ISP無關。聯絡您當地的ISP並詢問是否啟用了PMIP服務。
MAG未建立指向LMA的PMIPv6隧道（PBU和PBA資料包交換）。
診斷問題
1.檢查移動接入網關(MAG)上的配置。
2.檢查MAG和LMA之間的關聯。
MAG#sh ipv6 mobile pmipv6 mag binding MAG#
3.驗證PBU和PBA報文。
MAG#show ipv6 mobile pmipv6 mag stats ---------------------------------------- [MAG819]: Total Bindings : 0 [MAG819]: PBU Sent : 48 [MAG819]: PBA Rcvd : 36 [MAG819]: PBRI Sent : 0 [MAG819]: PBRI Rcvd : 0 [MAG819]: PBRA Sent : 0 [MAG819]: PBRA Rcvd : 0 [MAG819]: No Of handoff : 0 -------------------------------------------------

A)RESP to MCSA CREATE REQ表示MAG請求連線到LMA。當LMA拒絕PBU時，MAG從清除指示消息開始。
4.啟用debug ipv6 mobile mag events以驗證MAG上顯示的錯誤代碼。

要考慮的重要日誌：
A)MAG啟動與LMA的連線。
*4月17日18:13:22.885: [PMIPV6_MAG_EVENT]：事件已收到為Nai附加的新MNintf：路徑狀態機中的310410901877700@13511.mcs，路徑：Cellular0/1/0，狀態：PATH_NULL，新狀態：PATH_INIT
B)PBU從MAG傳送至LMA。
*4月17日18:13:22.885: [PMIPV6_MAG_EVENT]：傳送至Nai的PBU消息：310410901877700@13511.mcs
C)從LMA收到的PBA。

5.繼續捕獲路由器上的控制平面，並驗證確認資料包中的移動IPv6報頭。
比較捕獲
報頭有錯誤
![PMIPv6 Tunnel Not Established [Error]](/c/dam/en/us/support/docs/ios-nx-os-software/ios-xe-amsterdam-1731/220598-troubleshoot-pmip-tunnel-establishment-02.png)
標頭無錯誤
6.向本地ISP驗證。在這種情況下，為了建立反向隧道，LMA回覆不包含家鄉地址。
PMIPv6向LMA迴轉

診斷問題
1.驗證天線是否有良好訊號。
附註：手機網路故障排除超出本文檔的範圍。
2.啟用debug ipv6 mobile，以驗證裝置是否將PBU資料包傳送到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.

要考慮的重要日誌：
A)MAG使與LMA的連線過期並等待響應。
*5月9日20:28:26.784: [PMIPV6_LMN_EVENT]：連線計時器已過期
*5月9日20:28:26.784: [PMIPV6_LMN_EVENT]：事件已接收附加計時器過期狀態：LMN_READY，新狀態：LMN_READY
*5月9日20:28:26.784: [PMIPV6_MAG_EVENT]：事件已收到為Nai附加的舊MNintf: 310410901877700@13511.mcs（在路徑狀態機中），路徑： Cellular0/1/0，狀態： PATH_INIT，新狀態： PATH_INIT
*5月9日20:28:26.784: [PMIPV6_MAG_EVENT]：收到事件為Nai建立的第一個路徑：310410901877700@13511.mcs狀態：INIT，新狀態：INIT
B)傳送一條明確消息，刪除以前的繫結並建立新隧道。
*5月9日20:28:39.523: [PMIPV6_MAG_EVENT]：事件接收到Nai的最後路徑關閉：310410901877700@13511.mcs狀態：INIT，新狀態：NULL

*5月9日20:28:39.523: [PMIPV6_MAG_EVENT]:Nai:310410901877700@13511.mcs，已移除繫結
C)向LMA傳送PBU消息以建立新隧道0。一旦MAG收到，PBA就會啟動隧道。
*5月9日20:28:41.955: [PMIPV6_MAG_EVENT]:PBU消息傳送至Nai:310410901877700@13511.mcs
D)MAG和LMA接收並接受PBA。
*5月9日20:28:45.228: [PMIPV6_MAG_EVENT]：收到的消息：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

E)隧道0已建立。
*5月9日20:28:45.229: [PMIPV6_LMN_EVENT]：接收Tunnel0的地址更改事件
*5月9日20:28:45.229: %LINEPROTO-5-UPDOWN：介面Tunnel0上的線路協定，狀態更改為up
*5月9日20:28:45.230: %PMIPV6-5-TUNNELUP：啟用代理移動IPv6隧道Tunnel0
3.繼續路由器上的控制平面捕獲，並驗證資料包是否在MAG和LMA之間共用。
在匯出的捕獲中，MAG請求確認LMA。LMA將使用此消息進行響應；但是，由於傳輸出現問題，MAG無法一致地接收這些消息。
一旦傳輸穩定，隧道就會變得穩定。
4.與您的本地ISP確認這兩台裝置之間的傳輸是否穩定。
其他資訊
PMIP預計不會從ISP收到預設路由。為了獲得連線並建立隧道，必須具有指向LMA的IP的主機路由，並將蜂窩介面新增為下一跳。
範例：
ip route 203.0.113.10 255.255.255 cellular0/1/0
