需要帮助复制在路由器上的框架中继配置教程的结果。我需要更改/添加什么？

Question

我很难获得03:14显示在这里的输出：凯文·华莱士的帧中继配置

我的网络是3个路由器，每个路由器通过串行2/0接口连接到帧中继交换机，没有其他任何东西。我正试图建立一个轮毂和轮辐的拓扑，R1作为集线器，R2和R3作为辐条。所使用的帧中继开关是GNS3中默认的帧中继交换机应用程序。

更新:原来的问题解决了。第二个问题需要帮助：

最初的问题是由于配置错误的帧中继开关。然而，在每个路由器上，帧中继LMI已经更改为ANSI，以匹配帧中继.为什么帧中继的LMI类型仍然是错误的？也就是说，为什么它是CISCO而不是ANSI？

我的3台路由器的配置如下：

R1#sh run | s Serial2/0
interface Serial2/0
 description Conn to FR
 ip address 10.1.1.1 255.255.255.0
 encapsulation frame-relay
 serial restart-delay 0
 frame-relay lmi-type ansi

R2(config)#do sh run | s Serial2/0
interface Serial2/0
 description Conn to R1
 ip address 10.1.1.2 255.255.255.0
 encapsulation frame-relay
 serial restart-delay 0
 frame-relay lmi-type ansi

R3#sh run | s Serial2/0
interface Serial2/0
 description Conn to R1
 ip address 10.1.1.3 255.255.255.0
 encapsulation frame-relay
 serial restart-delay 0
 frame-relay lmi-type ansi

据我所知，我的路由器配置方式和凯文完全一样。但是，当我使用show frame-relay pvc命令或show frame-relay map命令时，我只获得有关第一个PVC/D8映射的信息：

R1#sh frame pvc

在本教程的输出中，R1显示PVCs 102和103，R2显示201，R3显示301。

此外，在帧中继地图方面：

R1#sh frame map
Serial2/0 (up): ip 10.1.1.2 dlci 102(0x66,0x1860), dynamic,
              broadcast,
              CISCO, status defined, active

R2#sh frame map
Serial2/0 (up): ip 10.1.1.3 dlci 103(0x67,0x1870), dynamic,
              broadcast,
              CISCO, status defined, active
Serial2/0 (up): ip 10.1.1.1 dlci 201(0xC9,0x3090), dynamic,
              broadcast,
              CISCO, status defined, active

R3#sh frame map
Serial2/0 (up): ip 10.1.1.2 dlci 301(0x12D,0x48D0), dynamic,
              broadcast,, status defined, active

为甚麽结果有差距呢？我刚开始使用帧中继，因此不知道我应该做什么。基本上，我和教程有什么不同？

P.S.每个路由器都是运行L3的GNS3中的IOU I86BI_LINUX-ADVENTERPRISEK9-M), Version 15.5(2)T设备

Answer 1

帧中继LMI是本地链路，这是在您的路由器和帧中继交换机之间。显然，您的帧中继开关配置为frame-relay lmi-type cisco。

Cisco支持用于帧中继的三种不同的本地管理接口( LMI )类型: Cisco、ANSI附件D和Q 933- A附件A。从Cisco IOS软件发布11.2开始，LMI自动识别功能允许帧中继接口自动检测直接连接的帧中继交换机支持的LMI类型。在从帧中继交换机接收到的<#>Based状态消息上，路由器会自动配置其帧中继接口，其支持的LMI类型由帧中继交换机确认。
