华为MPLS跨域带RR实验配置

news2024/10/7 20:36:42

Option B方案实验配置

配置建立Vpnv4邻居

配置反射器

配置RR和ASBR取消RT值检测

配置ASBR相连接口开启MPLS

配置ASBR向RR发送路由时更改下一跳

Option C1方案实验配置

Option C2方案实验配置

接口IP地址、底层IGP路由协议（ISIS）、MPLS LDP协议、PE与CE之间交互配置此处不做讲解（通跨域不带RR解决方案的配置）

1、为了减轻RR的负担，需要实现转发路径不经过RR，RR只作为控制层面（RR只传递路由，不传输数据）

2、RR不需要开启MPLS（如果RR参与数据转发了，就需要在接口开启MPLS）

Option B方案实验配置

配置建立Vpnv4邻居

PE和RR建立Vpnv4的IBGP邻居

ASBR和RR建立Vpnv4的IBGP邻居

ASBR和ASBR建立Vpnv4的EBGP邻居
