16.5-IPv6路由基础

在企业网络中，IPv6技术的应用越来越普及，IETF组织针对IPv6网络制定了两种路由协议：RIPng和OSPFv3

一、RIPng

RIPng发送路由更新的目的地址为组播地址FF02::9

RIPng中的路由条目下一跳地址是0::0或者link-local地址

二、RIPng配置

PC1与PC2相互访问

(1)手动配置静态路由

R1

[R1]ipv6 route-s 2003:: 64 2001::2

R2

[R2]ipv6 route-s 2002:: 64 2001::1

(2)配置RIPng

R1

<R1>sys
[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]ripng 1 enable
[R1-GigabitEthernet0/0/0]int g0/0/1
[R1-GigabitEthernet0/0/1]ripng 1 enable

R2

<R2>sys
[R2]int g0/0/0
[R2-GigabitEthernet0/0/0]ripng 1 enable
[R2-GigabitEthernet0/0/0]int g0/0/1
[R2-GigabitEthernet0/0/1]ripng 1 enable

查看IPv6路由表

[R1]dis ipv6 routing-table 

注：(1)IPv4 rip协议 udp520端口
IPv6 RIP协议 UDP521端口

(2)RIPng只有v1和RIP v1不是同一个协议

(3)关闭RIPng

[R1]undo ripng 1

全局模式下去使能RIPng

三、OSPFv3配置

OSPFv3要启用必须给路由器一个Router-ID（IPv4形式的RID）

R1

[R1]ospfv3
[R1-ospfv3-1]router-id	
[R1-ospfv3-1]router-id 1.1.1.1
[R1-ospfv3-1]qu
[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]ospfv3 1 area 0
[R1-GigabitEthernet0/0/0]int g0/0/1 
[R1-GigabitEthernet0/0/1]ospfv3 1 area 0

进入端口视图，宣告区域

R2

[R2]ospfv3
[R2-ospfv3-1]router-id 2.2.2.2
[R2-ospfv3-1]int g0/0/0
[R2-GigabitEthernet0/0/0]ospfv3 1 area 0
[R2-GigabitEthernet0/0/0]int g0/0/1
[R2-GigabitEthernet0/0/1]ospfv3 1 area 0
