幀中繼網絡部分配置完成，R3 pingR2,R4測試結果如下：
配置R2,R6,R7的ospfv3,為area0。

R7(config-if)#ipv6 address 2001:db8:99:2::3/64
R7(config-if)#ipv6 ospf 1 area 0
R7(config-if)#no shutdown
然后查看R7在area0的ospf的鄰居關系
R7#show ipv6 ospf neighbor
配置R6 F0/1,R7 F0/1,R8 F0/0 F0/1ospf area1為nssa 區域
R6:
R6(config)#ipv6 router ospf 1
R6(config-rtr)#area 1 nssa
R6(config-rtr)#int f0/1
R6(config-if)#ipv6 enable
R6(config-if)#ipv6 address 2001:db8:99:3::1/64

R8(config-if)#ipv6 enable
R8(config-if)#ipv6 address 2001:db8:99:4::2/64
R8(config-if)#ipv6 ospf 1 area 1
R8(config-if)#no shutdown
查看R8 ospfv3路由表
到此ipv6 ospfv3部分配置完成，測試R4 ping R8成功
配置R5到R8 RIPng部分並且重分布到ospfv3
R5:
R5(config)#ipv6 unicast-routing
R5(config)#ipv6 router rip 1
R5(config)#int fastEthernet 0/0
R5(config-if)#ipv6 enable
R5(config-if)#ipv6 address 2001:Db8:99:5::1/64
R5(config-if)#ipv6 rip 1 enable
R5(config-if)#no shutdown
R8:
R8(config)#ipv6 router rip 1
R8(config)#int fastEthernet 1/0
R8(config-if)#ipv6 enable
R8(config-if)#ipv6 address 2001:Db8:99:5::2/64
R8(config-if)#ipv6 rip 1 enable
R8(config-if)#no shutdown
R8(config-if)#exit
R8(config)#ipv6 router ospf 1
R8(config-rtr)#redistribute rip 1
R8(config-rtr)#redistribute connected
R8(config-rtr)#exit
R8(config)#ipv6 router rip 1
R8(config-rtr)#redistribute ospf 1
R8(config-rtr)#redistribute connected
查看R5路由表,可獲取area1,無法獲取area 0和area2,可ping通R8
Ipv6的部分也做了一晚上，需要配置的地方很多很復雜，一個不小心就會配置出錯，不是打錯地址就是漏打什么，十分的考驗耐心。配置已經到了最后的階段，僅剩的幾行代碼，最后的實驗結果就要出來了，可是正好十一點到了，電腦斷網導致Vmware橋接模式的GNS3虛擬機IP失效了，GNS3也找不到服務器IP崩潰，我沉默了很久，放棄了再一次的配置。
