R2环回

[r2-LoopBack0]ipv6 enable 
[r2-LoopBack0]ipv6 address 2002:1701:0101:2::1/64
 

起ripng

[r1-LoopBack0]ripng 1 enable 
[r1]int lo 1 
[r1-LoopBack1]ripng 1 enable

查询是否学到各自环回
[r1]display ipv6 routing-table protocol ripng

将R1上的两个环回汇总
[r1]int g0/0/1
[r1-GigabitEthernet0/0/1]ripng summary-address 2002:1701:0101:: 64

[r8-LoopBack0]ipv6 address  2002:2201:0102:8006::1/64
 

as2起ospfv3

[r5]ospfv3 1
[r5-ospfv3-1]router-id 5.5.5.5 
[r5-ospfv3-1]int lo 0 
[r5-LoopBack0]ospfv3 1 area 0
[r5-LoopBack0]int g0/0/1
[r5-GigabitEthernet0/0/1]ospfv3 1 area 0
R6\7\8同理

至此R5678ospf已同

起bgp

[r4]bgp 1 
[r4-bgp]router-id 4.4.4.4
[r4-bgp]peer 2002:2201:102:1::2 as-number 2- 
[r4-bgp]ipv6-family 
[r4-bgp-af-ipv6]peer 2002:2201:102:1::2 enable

[r5]bgp 64512 
[r5-bgp]router-id 5.5.5.5
[r5-bgp]confederation id 2
[r5-bgp]peer 2002:2201:102:1::1 as-number 1 
[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
 

R5R7 EBGP

[r5]bgp 64512 
[r5-bgp]router-id 5.5.5.5
[r5-bgp]confederation id 2
[r5-bgp]peer 6::6 as-number 64512 
[r5-bgp]peer 6::6 connect-interface lo 0  5::5
[r5-bgp]ipv6-family  
[r5-bgp-af-ipv6]peer 6::6 enable

[r7]bgp 64512 
[r7-bgp]router-id 7.7.7.7
[r7-bgp]confederation id 2
[r7-bgp]peer 6::6 as-number 64512 
[r7-bgp]peer 6::6 connect-interface lo 0  7::7
[r7-bgp]peer 8::8 as-number 64513 
[r7-bgp]peer 8::8 connect-interface lo 0  7::7
[r7-bgp]peer 8::8 ebgp-max-hop 2
[r7-bgp]ipv6-family 
[r7-bgp-af-ipv6]peer 6::6 enable  
[r7-bgp-af-ipv6]pee 8::8 enable 
 

右边起tunnel

[r4]int Tunnel 0/0/0
[r4-Tunnel0/0/0]tunnel-protocol ipv6 6to4 
[r4-Tunnel0/0/0]ipv6 enable 
[r4-Tunnel0/0/0]ipv6 address  2002:2201:0102:2::1/64 
[r4-Tunnel0/0/0]source 34.1.1.2
[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
[r6-bgp]ipv6-family
[r6-bgp-af-ipv6]peer 7::7 reflect-client

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
