用凡科做网站要钱吗,百度导航下载2020新版语音,wordpress 文章标题字体,wordpress 添加html链接后404一.需求 1.AS1存在两个环回，一个地址为192.168.1.0/24，该地址不能再任何协议中宣告 AS3存在两个环回，一个地址为192.168.2.0/24，该地址不能再任何协议中宣告 AS1还有一个环回地址为10.1.1.0/24，AS3另一个环回地址是…

一.需求

1.AS1存在两个环回，一个地址为192.168.1.0/24，该地址不能再任何协议中宣告

AS3存在两个环回，一个地址为192.168.2.0/24，该地址不能再任何协议中宣告

AS1还有一个环回地址为10.1.1.0/24，AS3另一个环回地址是11.1.1.0/24

最终要求这两个环回可以互相通讯。

2.整个AS2的IP地址为172.16.0.0/16

3.AS间的骨干链路Ip地址随意分配

4.使用BGP协议让整个网络所有设备的环回可以互相访问

5.减少路由条目数量，避免环路出现

完成上图内容，使用联邦+反射器

二.需求分析

1.AS1 和 AS3 各有一个特定环回地址禁止宣告，另一个环回地址需实现互通

2.AS2 需使用 172.16.0.0/16 进行 IP 地址规划​

3.AS 间骨干链路 IP 自主分配，保证链路互联互通且地址不冲突。​

4.利用 BGP 协议，通过联邦和反射器实现全网设备环回地址相互访问。​

5.减少路由条目数量，通过合适的 BGP 机制和策略，避免网络出现环路。

三.配置
