Cisco路由器在帧中继中的配置实例
1.帧中继技术
帧中继是一种高性能的WAN协议，它运行在OSI参考模型的物理层和数据链路层。
它是一种数据包交换技术，是X.25的简化版本。
它省略了X.25的一些强健功能，如提供窗口技术和数据重发技术，而是依靠高层协议提供纠错功能，这是因为帧中继工作在更好的WAN设备上，这些设备较之X.25的WAN设备具有更可靠的连接服务和更高的可靠性，它严格地对应于OSI参考模型的最低二层，而X.25还提供第三层的服务，所以，帧中继比X.25具有更高的性能和更有效的传输效率。
帧中继广域网的设备分为数据终端设备（DTE）和数据电路终端设备（DCE），Cisco路由器作为DTE设备。
帧中继技术提供面向连接的数据链路层的通信，在每对设备之间都存在一条定义好的通信链路，且该链路有一个链路识别码。
这种服务通过帧中继虚电路实现，每个帧中继虚电路都以数据链路识别码（DLCI）标识自己。
DLCI的值一般由帧中继服务提供商指定。
帧中继即支持PVC也支持SVC。
帧中继本地管理接口（LMI）是对基本的帧中继标准的扩展。
它是路由器和帧中继交换机之间信令标准，提供帧中继管理机制。
它提供了许多管理复杂互联网络的特性，其中包括全局寻址、虚电路状态消息和多目发送等功能。

任务
命令
设置FrameRelay封装
encapsulationframe-relay[ietf]1
设置FrameRelayLMI类型
frame-relaylmi-type{ansi|cisco|q933a}2
设置子接口
interfaceinterface-typeinterface-number.subinterface-number[multipoint|point-to-point]
映射协议地址与DLCI
frame-relaymapprotocolprotocol-addressdlci[broadcast]3
设置FRDLCI编号
frame-relayinterface-dlcidlci[broadcast]
注：
1.若使Cisco路由器与其它厂家路由设备相连，则使用Internet工程任务组（IETF）规定的帧中继封装格式。
2.从CiscoIOS版本11.2开始，软件支持本地管理接口（LMI）“自动感觉”，“自动感觉”使接口能确定交换机支持的LMI类型，用户可以不明确配置LMI接口类型。
3.broadcast选项允许在帧中继网络上传输路由广播信息。
