2020年5月29日 · 本文详细介绍了BGP协议中的AS_Path属性如何影响路径选择，包括原理概述、实验练习和通过修改AS_Path属性控制BGP选路的方法。 通过具体实验，展示了AS_Path属性在BGP选路中的作用及如何通过策略修改AS_Path来实现路径控制。

You can get a path in the BGP table through the BGP network command, redistribution, or aggregation. A BGP router will prefer routes that it installed into BGP itself over a route that another router installed in BGP.

2024年12月2日 · BGP selects the best path out of these 9 paths through the consideration of various attributes that are explained in this document. In the output shown here, BGP compares the available paths and selects Path 6 as the best path based on its lower router-ID.

2013年2月12日 · This document outlines the BGP best path selection algorithm, and covers specific configuration examples on how to manipulate BGP’s best path decision based on different attributes. Initial Topology

2024年12月2日 · We explain how BGP selects the best path to destinations based on a list of attributes. We also look at the code involved and provide explanatory diagrams and tables.

在bgp协议中，as-path属性是路由信息的一个关键组成部分，它是一个有序的as号列表，表示了一个bgp路由从起源as到接收该路由的as所经过的所有as的序列。

1 天前 · AS-Path（Autonomous System Path）是BGP协议中的一个公认强制属性，用于记录BGP路由从源到目的地所经过的所有AS（自治系统）的编号集合。 通过AS-Path，BGP能够有效避免路由环路，同时帮助网络管理员了解路由的传播路径。

2024年12月8日 · BGP path selection is governed by a set of attributes associated with each route. These attributes provide valuable information about the path and help BGP make informed decisions. The most significant attributes include: AS Path: This attribute represents the sequence of Autonomous Systems (AS) a packet traverses. A shorter AS path length is ...

2025年3月16日 · 5. BGP路径属性详解 5.1 公认必遵属性. 起源（Origin）：表示路由的来源，分为IGP、EGP和Incomplete三种。 AS路径（AS_PATH）：表示到达目的网络的AS路径。 下一跳（Next_Hop）：表示到达下一跳路由器的IP地址。 5.2 公认任意属性. 本地优先级（Local_Pref）：表示本地路由器的优先级，值越高优先级越高。

2024年11月13日 · BGP (Border Gateway Protocol) is a routing protocol designed to exchange routing and reachability information between different Autonomous Systems (ASes), which are large networks or collections of networks managed by a …
