### 实验拓扑 ###

R1、R2为IPv6路由器，双方使用GE0/0/0口互联

### 实验需求 ###

*  R1、R2按照图示完成接口IP地址的配置；
 *  R1、R2运行OSPFv3，要求R1与R2的Loopback0接口能够互相通信。

### 配置及实现 ###

R1的配置如下：

[R1] ipv6
    
    [R1] ospfv3 1 #创建OSPFv3进程，并配置router-id为1.1.1.1
    [R1-ospfv3-1] router-id 1.1.1.1
    
    [R1] interface gigabitEthernet0/0/0
    [R1-GgabitEthernet0/0/0] ipv6 enable
    [R1-GgabitEthernet0/0/0] ipv6 address 2001:12::1 64
    [R1-GgabitEthernet0/0/0] ospfv3 1 area 0 #接口激活OSPFv3，加入区域0
    
    [R1] interface loopback 0
    [R1-LoopBack0] ipv6 enable
    [R1-LoopBack0] ipv6 address 2001:0001::FFFF 128
    [R1-LoopBack0] ospfv3 1 area 0 #接口激活OSPFv3，加入区域0

R2的配置如下：

[R2] ipv6
    
    [R2] ospfv3 1
    [R2-ospfv3-1] router-id 2.2.2.2
    
    [R2] interface gigabitEthernet0/0/0
    [R2-GgabitEthernet0/0/0] ipv6 enable
    [R2-GgabitEthernet0/0/0] ipv6 address 2001:12::2 64
    [R2-GgabitEthernet0/0/0] ospfv3 1 area 0
    
    [R2] interface loopback0
    [R2-LoopBack0] ipv6 enable
    [R2-LoopBack0] ipv6 address 2001:0002::FFFF 128
    [R2-LoopBack0] ospfv3 1 area 0

完成配置后，两台PC即可互相通信。下面做一些简单的查看和验证：

[R1] display ospfv3 peer
    OSPFv3 Process (1)
    OSPFv3 Area (0.0.0.0)
    Neighbor ID Pri State Dead Time Interface Instance ID
    2.2.2.2 1 Full/Backup 00:00:35 GE0/0/0 0

上面的输出是R1的OSPFv3邻居表，可以看到R1有一个OSPFv3的邻居，也就是R2（2.2.2.2），并且该邻居的状态为Full，再来看一下邻居的详细信息：

[R1] display ospfv3 peer verbose
    OSPFv3 Process (1)
    Neighbor 2.2.2.2 is Full, interface address FE80::2E0:FCFF:FEFB:2E46
    In the area 0.0.0.0 via interface GE0/0/0
    DR Priority is 1 DR is 1.1.1.1 BDR is 2.2.2.2
    Options is 0x000013 (-|R|-|-|E|V6)
    Dead timer due in 00:00:37
    Neighbour is up for 00:01:03
    Database Summary Packets List 0
    Link State Request List 0
    Link State Retransmission List 0
    Neighbour Event: 14
    Neighbour If Id : 0x3

接下去查看一下R1的IPv6路由表：

[R1] display ipv6 routing-table protocol ospfv3
    Public Routing Table : OSPFv3
    Summary Count : 3
    OSPFv3 Routing Table's Status : < Active >
    Summary Count : 1
    Destination : 2001:2::FFFF PrefixLength : 128
    NextHop : FE80::2E0:FCFF:FEFB:2E46 Preference : 10
    Cost : 1 Protocol : OSPFv3
    RelayNextHop : :: TunnelID : 0x0
    Interface : GigabitEthernet0/0/0 Flags : D
    [ 此处省略部分输出 ]

R1已经学习到了2001:2::FFFF/128的OSPF路由，同样，R2也学习到了2001:1::FFFF/128的路由。

现在来测试一下R1与R2的Loopback0接口的IP连通性：

[R1] ping ipv6 -a 2001:1::FFFF 2001:2::FFFF
    PING 2001:2::FFFF : 56 data bytes, press CTRL_C to break
    Reply from 2001:2::FFFF
    bytes=56 Sequence=1 hop limit=64 time = 30 ms
    Reply from 2001:2::FFFF
    bytes=56 Sequence=2 hop limit=64 time = 20 ms
    Reply from 2001:2::FFFF
    bytes=56 Sequence=3 hop limit=64 time = 20 ms
    Reply from 2001:2::FFFF
    bytes=56 Sequence=4 hop limit=64 time = 20 ms
    Reply from 2001:2::FFFF
    bytes=56 Sequence=5 hop limit=64 time = 20 ms
    --- 2001:2::FFFF ping statistics ---
    5 packet(s) transmitted
    5 packet(s) received
    0.00% packet loss
    round-trip min/avg/max = 20/22/30 ms
