[r5-bgp]ipv6-family
[r5-bgp-af-ipv6]peer 2002:2201:102:1::1 enable
利用IPV6多宿主特点在环回在配置一个ip地址便于bgp配置
[r5]int lo 0
[r5-LoopBack0]ipv6 address 5::5/64----R6\7\8同理

[r4]ipv6 route-static 2002:: 16 Tunnel 0/0/0
[r4]bgp 1
[r4-bgp]ipv6-family
将tunnel宣告到右边区域传给R5\6\7\8
[r4-bgp-af-ipv6]network 2002:: 16
由于R4\R5为EBGP关系，因此R4传给R5时R5学到的此条目为优，但R5\R6为IBGP，只能传一跳，此时需要在EBGPR5上改下一跳属性，使R6学到此路由条目为优
[r5]bgp 64512
[r5-bgp]ipv6-family
[r5-bgp-af-ipv6]peer 6::6 next-hop-local
解决ibgp水平分割
[r6]bgp 64512

在R5上汇总
[r5]ipv6 route-static 2002:2201:0102:8000:: 49 null 0
[r5]bgp 64512
[r5-bgp]ipv6-family
[r5-bgp-af-ipv6]network 2002:2201:0102:8000:: 49
注：在做实验的过程中因为路由器不能用其他只能使用Router名称的路由器也就是软件自带而不是注册的路由器 所以 ripng 功能不能启用 ospfv3功能也不能使用，别问我怎么知道的，TvT， 所以只能在网页上搜寻一样的题来进行学习
