3.Distance Vector(距离矢量类型):是一种基于 “距离" 和 “方向" 的动态路由协议,如下图所示。该类型的路由协议有:RIP、BGP。 1. 距离:指示了到达目的网络的度量值,即:所要经过路由器的个数。 2. 方向:指示了到达目的网络的下一跳设备。 Link State(链路状态类型):是一种基于 LSDB(链路状态数据库)的动...
动态路由协议按照区域划分,可分为内部网关协议IGP(Interior Gateway Protocol)和外部网关协议EGP(Exterior Gateway Protocol), 按照执行的算法分类,又可分为距离矢量路由协议(Distance Vector)和链路状态路由协议(Link State) 3.1按照路由算法分:距离-矢量路由和链路状态路由协议 3.1.1距离-矢量路由:RIP 基于距离-矢量算法...
BGP是一种距离矢量(Distance-Vector)路由协议。 BGP从设计上避免了环路的发生。 AS之间:BGP通过携带AS路径信息来标记途经的AS,带有本地AS号的路由将被丢弃,从而避免了域间产生环路。 AS内部:BGP在AS内学到的路由不再通告给AS内的BGP邻居,避免了AS内产生环路。 BGP提供了丰富的路由策略,能够对路由实现灵活的过滤...

按照执行的算法分类,又可分为距离矢量路由协议(Distance Vector)和链路状态路由协议(Link State) 3.1 3.1.1 基于距离-矢量算法将周期性地将路由表发送给与其直连的网络邻居。每个接收者加上一个距离矢量,或它自己的距离“值”到表中,并将其转发给直接邻居。这个过程发生在直接相连的路由器之间,并使得每个路由器得到...

Distance-vector protocols, such as the Routing Information Protocol (RIP) Link state protocols, such as Open Shortest Path First (OSPF) and Intermediate System to Intermediate System (IS-IS) Although these protocols are designed for different purposes and have different behavior characteristics, they ...
This document discusses the usage and applicability of BGP Link-State Shortest Path First (BGP-SPF) extensions in data center networks utilizing Clos or Fat-Tree topologies. The document is intended to provide simplified guidance
The AS_Path attribute records the numbers of all ASs through which a route passes from the local end to the destination in the distance-vector order. When a BGP speaker advertises a local route: When advertising the route beyond the local AS, the BGP speaker adds the local AS number to ...
BGP is an inter-autonomous system routing protocol based on the distance-vector algorithm. It is used to exchange routing information across the Internet and is the only protocol that is designed to deal with a network of the Internet's size and the only protocol that can deal well with havi...
