S5820 IPV6 BGP4+ RR二级路由反射器典型组网配置案例

组网说明：

本案例采用H3C HCL模拟器的S5820交换机来模拟ipv6 BGP RR二级路由反射器的典型组网配置。其中SW1、SW2、SW3属于AS100，SW4属于AS200，由于SW1、SW2与SW4没有互联，同时又想实现业务地址之间的互通，因此需要使用BGP RR二级路由反射器来实现。SW2是SW1的一级RR反射，SW3是SW2的二级反射。SW1与SW2，SW2与SW3建立IBGP邻居关系，为了SW1与SW2，SW2与SW3建立IBGP邻居关系及RR路由反射，因此SW1、SW2、SW3之间建立OSPFv3邻居关系来进行承载。最后SW3与SW4建立EBGP邻居关系。
