BGP与IPv6配置指南
BGP简介
Border Gateway Protocol（BGP）是一种在互联网中用于路由选择的协议，它允许自治系统（AS）之间的路由器交换路由信息，以实现网络之间的互联，随着互联网的快速发展，IPv6作为下一代互联网协议，已经成为网络建设的重要方向，本文将介绍如何在BGP环境中配置IPv6。
BGP与IPv6
BGP与IPv6的关系
BGP是IPv6网络中不可或缺的一部分,它负责在IPv6网络中交换路由信息，由于IPv6地址长度较长，因此在BGP环境中配置IPv6需要特别注意。
BGP与IPv6的配置需求
（1）确保BGP路由器支持IPv6协议；
（2）配置IPv6接口；
（3）设置BGP邻居，实现IPv6路由信息交换；
（4）配置BGP路由策略，实现IPv6路由优化。
BGP与IPv6配置步骤
确保BGP路由器支持IPv6
在配置BGP与IPv6之前,首先要确保BGP路由器支持IPv6协议，不同厂商的路由器支持情况可能有所不同，请查阅相关设备手册。
配置IPv6接口
（1）创建IPv6接口：在路由器上创建IPv6接口，如eth0.100。
（2）配置IPv6地址：为IPv6接口分配一个全球唯一的IPv6地址。
（3）启用IPv6接口：使用命令启用IPv6接口。
设置BGP邻居
（1）创建BGP邻居：在BGP配置模式下，创建BGP邻居，指定邻居的IPv6地址。
（2）配置邻居参数：设置邻居参数，如路由反射器、邻居保持时间等。
配置BGP路由策略
（1）创建路由策略：在BGP配置模式下，创建一个IPv6路由策略。
（2）设置策略规则：为IPv6路由策略设置规则，如路由过滤、路由聚合等。
（3）应用路由策略：将IPv6路由策略应用到BGP邻居。
BGP与IPv6配置示例
以下是一个简单的BGP与IPv6配置示例：
