进行路由再分布(redistribution)可以实现两个或多个网络的互联,然而,如对多协议网络的路由不加以管理,可能会出现一些意想不到的问题。同一路由器(路由再分布点的路由器)从两个协议都学到到达同一目标的路由,该选哪一协议路由呢? 网络会选择管理距离较小的路由。但是,如果所有协议路由都按其缺省的管理距离运行而不对某些协议路由进行控制,网络很可能存在很大的缺陷。因此,用distance命令改变管理距离以及用distribute-list命令控制某些协议路由是网络路由管理中的一项非常重要的技术。

Routing redistribution can achieve the interconnection of two or more networks. However, some unexpected problems may occur if the routing of the multi-protocol network is not managed. The same router (route redistribution point of the router) learned from both protocols to reach the same goal of the route, the election which protocol routing? The network will choose to manage the smaller distance routing. However, if all protocol routes run at their default management distance without controlling certain protocol routes, the network is likely to be significantly flawed. Therefore, changing the administrative distance with the distance command and using the distribute-list command to control certain protocol routes is a very important technique in network routing management.
