摘 要

实验中关于银行地区网点与分行互联的最终要求是实现网点之间不能互访,但都可以访问分行。为了实现此目的,可以用路由过滤,精确重分发,MPLS VPN架构这三种方式。其中可以通过RIP和EIGRP来实现路由过滤;以OSPF作为骨干,其他协议做分支,通过标记路由,可以实现精确路由重分发;通过MPLS VPN的RT导入导出可以控制实现此目的。当进行路由分配时,由于相比于RIP路由器更加信任IGRP,可能会产生路由回馈的现象,即被通告路由沿错误方向穿过重新分配路由器。使用路由过滤则可以使网络管理员对路由通告施加严格的控制,防止这种情况的发生。同时路由过滤还可以建立路由防火墙,来达到对网络的保护效果。在网络搭建中,不同的系统会使用不同的动态路由协议,所以存在多种不同的协议并存的情况。同时在实际的工作过程中,无法确保使用的工作设备全部来自于同一个厂商,而不同厂商提供的设备所支持的协议也不同,所以需要使用路由重分布来对进行梳理。在实际工作工程中,为了完成不同的工作要求,会使用到不同的路由协议,为了在同一个网络中有效地支持多种路由协议,必须在不同的路由协议之间共享路由信息。为了完成以上的目标,我们可以使用路由重分发来对其中所使用到的路由协议进行梳理整合,来使网络正常运行。

Design and implementation of interconnection between regional branches and branches of a bank in Jiangsu Province

Abstract

In the experiment, the ultimate requirement of the interconnection between regional branches and branches is to realize that the branches can not visit each other, but can visit each other. In order to achieve this goal, we can use route filtering, precise redistribution and MPLS VPN architecture. The routing filtering can be realized by rip and EIGRP; With OSPF as the backbone and other protocols as branches, precise route redistribution can be realized by marking route; This can be achieved by RT import and export of MPLS VPN. When routing assignment is carried out, because the router trusts IGRP more than rip router, it may produce routing feedback phenomenon, that is, the notified route passes through the reallocated router in the wrong direction. By using route filtering, network administrators can exercise strict control over route advertisements to prevent this situation. At the same time, routing filtering can also establish routing firewall to achieve the effect of network protection.In the network construction, different systems will use different dynamic routing protocols, so there are many different protocols coexisting. At the same time, in the actual work process, it is impossible to ensure that all the working devices used come from the same manufacturer, and the protocols supported by the devices provided by different manufacturers are also different, so it is necessary to use routing redistribution to sort out. In practical work, in order to complete different work requirements, different routing protocols will be used. In order to effectively support multiple routing protocols in the same network, routing information must be shared between different routing protocols. In order to achieve the above goals, we can use route redistribution to sort out and integrate the routing protocols used in it to make the network run normally.
