LISP（Locator/ID Separation Protocol，位置/ID分离协议）协议提供了一种新型的网络架构，把IP地址分为两个独立的地址空间：
· EID（Endpoint Identifier，节点标识符）地址空间：通信节点的主机地址。
· RLOC（Routing Locator，路由标识符）地址空间：LISP路由器的地址。
RLOC用来表明位置，定义了设备如何接入网络，如何能被找到；EID用来表明位置，定义了设备是谁，属于什么组织。站点发出的数据包被打上两层包头，内部包头为EID，外部包头为RLOC，设备依靠RLOC地址将数据包发送出去，到目的设备后去掉外部RLOC包头，根据EID将数据包送到目的站点，这种模式称为映射与封装机制。由于这种机制采用的是两层封装的方式，大部分网络设备无需做很多改动，只需网络边缘的路由器支持数据包的封装和解封装即可。
LISP协议具有下列优点：
· 可解决当前Internet网络过大，路由表过多的问题；
· 通信终端位置发生变化，其EID地址可以保持不变，可实现园区内的移动办公；
· 可实现跨三层的虚拟机迁移，同时解决迁移后访问路径的优化问题；
· 可实现虚拟化/多租户。
图1-1 LISP协议设计示意图
如图1-1所示：
· 核心网络：使用PA（Provider Allocated，分发提供者）地址，用于核心网的路由。
· 客户网络：内部使用PI（Provider Independent，独立提供者）地址，既作为主机的标识符也用于内部的路由寻址。
· ITR（Ingress Tunnel Router，入方向隧道路由器）：接收到从终端发送来的报文，对报文进行LISP封装，通过LISP隧道发送给远端的ETR设备。
· ETR（Egress Tunnel Router，出方向隧道路由器）：接收到ITR发送过来的LISP数据报文，解除LISP封装，然后将此报文按照EID地址进行转发。
· xTR：同时支持ITR和ETR功能的设备，称为xTR。
· FHR（First Hop Router，第一跳路由器）：在大二层网络下的多跳迁移场景中，主机直连的路由器称为第一跳路由器，负责迁移主机发现，并通知Site GW xTR设备。
· Site GW xTR：在大二层网络下的多跳迁移场景中，站点网关xTR设备负责数据包的封装和解封装。
目前只实现了4O4（IPv4 to IPv4）的封装。
LISP数据平面主要进行隧道封装，即对原始的IP报文进行UDP封装，并添加LISP头信息，共增加长度36～56字节，协议可以支持4O4/4O6/6O4/6O6封装。具体的报文头如图1-2所示。
LISP控制平面主要进行映射信息控制。
基本概念：
· Mapping-Database：EID地址与RLOC地址的映射关系，每个LISP站点的所有ETR上都维护有本站点的EID-to-RLOC映射关系。
· MS（Map Server，映射服务器）：负责接收ETR发送的注册报文，维护映射关系。
· MR（Map Resolver，映射解答者）：负责处理请求报文。
MS和MR为同一台设备。
LISP协议报文为UDP报文，端口号为4342。LISP协议报文共分为下面几种：
· Map-Request：请求报文。ITR通过发送请求报文向MR或者ETR请求EID-to-RLOC映射。请求报文的UDP目的端口号为4342，源端口号随机生成。
· Map-Reply：应答报文。ETR通过回应应答报文来响应请求报文。应答报文的UDP源端口号为4342，目的端口号为请求报文源端口号。
· Map-Register：注册报文。ETR周期性地向MS发送注册报文，将本站点的EID-to-RLOC映射关系向MS注册。注册报文的UDP目的端口号为4342，源端口号随机生成。
· ECM（Encapsulated Control Message，封装控制信息）：隧道封装报文。当ITR发送请求报文给MR，或者MS转发请求报文给ETR时，使用ECM封装。即在原请求报文的外层，再添加一层LISP封装，外层的源地址、目的地址都是全局RLOC地址，UDP目的端口号为4342，源端口号为随机生成。
· Map-Notify：通知报文。当ETR发送注册报文给MS，MS收到之后会回应通知报文给ETR，用于通知ETR注册报文已经收到并处理。
· Map-ACK：确认报文。ETR收到通知报文之后，向MS回应确认报文，通知MS已经收到此通知报文。
注册过程如下：
(1) ETR周期性地将本站点的EID-to-RLOC映射信息通过注册报文向MS注册；
(2) MS收到注册报文，记录对应站点的映射关系。
请求过程如下：
(1) 主机通过DNS服务器得到要通信的对端的IP地址，并将报文发送给ITR；
(2) ITR检查源地址为EID地址，并且本地没有对应的映射关系，于是向MR发送请求报文，此请求报文被封装在ECM报文中发送给MR；
(3) MR收到ECM报文后进行解封装，然后将请求报文转给MS处理；
(4) MS根据本地注册的映射关系，将此请求报文重新进行ECM封装，并发送给对应的ETR处理；
(5) ETR收到此请求报文，解开ECM封装，根据本地维护的映射关系，向ITR回应应答报文；
(6) ITR收到应答报文，根据应答报文中的信息，维护映射关系；
(7) ITR下一次再收到主机发送的数据报文时，便可根据映射关系将数据报文进行LISP封装，发送到ETR处理了。

LISP网络支持多实例。当不同租户的流量需要在不同的站点之间扩展时，可以采用多个实例来实现。每个实例使用实例ID来唯一标识。如图1-3中定义了三个LISP实例。
多实例实现了以下功能：
· LISP的控制报文和数据报文中都可以携带24位的实例ID，通过实例实现了虚拟化；
· 不同租户的控制信息和数据流被实例ID标记，映射关系在数据库和缓存中同样被标记；
· 实例ID可以映射为VRF的实例ID。在边缘设备上通过VRF实现不同缓存；
· LISP支持两级虚拟化，EID和RLOC可以分别映射不同的实例ID。
支持不同子网下的虚拟机迁移。例如，在数据中心的灾备模式下使用。
图1-4 跨网段虚拟机迁移应用场景示意图
在大二层网络下的虚拟机迁移以及虚拟机多跳迁移，需要与EVI结合使用。例如，在双活数据中心中使用。
图1-5 同网段虚拟机迁移应用场景示意图
与LISP相关的协议规范有：
· RFC 6830：The Locator/ID Separation Protocol(LISP)
· RFC 6833：Locator/ID Separation Protocol (LISP) Map-Server Interface
· RFC 6835：The Locator/ID Separation Protocol Internet Groper(LIG)

· 配置接口的网络层地址，使相邻节点网络层可达
· 配置LISP的基本功能
ITR在发送请求报文时，如果自身也是ETR，可以将自身的映射信息携带在请求报文中。ETR可以选择直接接受并缓存请求报文中的映射信息，这样可以加快缓存速度。

LIG（LISP Internet Groper）是一种探测解析机制。LIG给管理员提供一个CLI命令，让用户可以在没有数据发送的情况下，通过命令行在设备上建立映射信息。
LIG通过触发一次Map请求和应答过程，获取一个EID/RLOC数据库映射表项，并将结果显示给用户，请求的EID可以是路由器或主机的EID，主要应用在下面两个场景：
(1) 获取特定EID在映射数据库中的映射信息；
(2) 确认站点是否成功向MS注册。
在任意视图下执行lig命令可以用来查询EID数据库映射关系。
