R1、R2為IPv6路由器，雙方使用GE0/0/0口互聯(lián)

實(shí)驗(yàn)需求

R1、R2按照?qǐng)D示完成接口IP地址的配置；

R1、R2運(yùn)行OSPFv3，要求R1與R2的Loopback0接口能夠互相通信。

配置及實(shí)現(xiàn)

R1的配置如下：

[R1]?ipv6

[R1]?ospfv3?1?#創(chuàng)建OSPFv3進(jìn)程，并配置router-id為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?2001:1?64
[R1-GgabitEthernet0/0/0]?ospfv3?1?area?0?#接口激活OSPFv3，加入?yún)^(qū)域0

[R1]?interface?loopback?0
[R1-LoopBack0]?ipv6?enable
[R1-LoopBack0]?ipv6?address?2001:FFFF?128
[R1-LoopBack0]?ospfv3?1?area?0?#接口激活OSPFv3，加入?yún)^(qū)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?2001:2?64
[R2-GgabitEthernet0/0/0]?ospfv3?1?area?0

[R2]?interface?loopback0
[R2-LoopBack0]?ipv6?enable
[R2-LoopBack0]?ipv6?address?2001:FFFF?128
[R2-LoopBack0]?ospfv3?1?area?0

完成配置后，兩臺(tái)PC即可互相通信。下面做一些簡(jiǎn)單的查看和驗(yàn)證：

[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?0035?GE0/0/0?0

上面的輸出是R1的OSPFv3鄰居表，可以看到R1有一個(gè)OSPFv3的鄰居，也就是R2（2.2.2.2），并且該鄰居的狀態(tài)為Full，再來看一下鄰居的詳細(xì)信息：

[R1]?display?ospfv3?peer?verbose
OSPFv3?Process?(1)
Neighbor?2.2.2.2?is?Full,?interface?address?FE80:FCFF2E46
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?0037
Neighbour?is?up?for?0003
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?:?
Summary?Count?:?1
Destination?:?2001:FFFF?PrefixLength?:?128
NextHop?:?FE80:FCFF2E46?Preference?:?10
Cost?:?1?Protocol?:?OSPFv3
RelayNextHop?:?::?TunnelID?:?0x0
Interface?:?GigabitEthernet0/0/0?Flags?:?D
[?此處省略部分輸出?]

R1已經(jīng)學(xué)習(xí)到了2001:FFFF/128的OSPF路由，同樣，R2也學(xué)習(xí)到了2001:FFFF/128的路由。

現(xiàn)在來測(cè)試一下R1與R2的Loopback0接口的IP連通性：

[R1]?ping?ipv6?-a?2001:FFFF?2001:FFFF
PING?2001:FFFF?:?56?data?bytes,?press?CTRL_C?to?break
Reply?from?2001:FFFF
bytes=56?Sequence=1?hop?limit=64?time?=?30?ms
Reply?from?2001:FFFF

Reply?from?2001:FFFF

Reply?from?2001:FFFF

Reply?from?2001:FFFF
