实验四 IPV6 ripng实验

实验 2: IPv6 RIPng

1.实验目的

通过本实验可以掌握

（1）启用 IPv6 流量转发

（2）向 RIPng 网络注入默认路由

（3）RIPng 配置和调试

2.拓扑结构

实验拓扑如图 23-2 所示。

图 23-2 IPv6 RIPng 配置

3.实验步骤

（1）步骤 1：配置路由器 R1

R1(config)#ipv6 unicast-routing

R1(config)#ipv6 router rip cisco //启动 IPv6 RIPng 进程

R1(config-rtr)#split-horizon //启用水平分割

R1(config-rtr)#poison-reverse //启用毒化反转

R1(config)#interface Loopback0

R1(config-if)#ipv6 address 2006:1111::1/

R1(config-if)#ipv6 rip cisco enable //在接口上启用 RIPng

R1(config)#interface Serial0/0/0

R1(config-if)#ipv6 address 2007:12::1/

R1(config-if)#ipv6 rip cisco enable

R1(config-if)#ipv6 rip cisco default-information originate

//向 IPv6 RIPng 区域注入一条默认路由（：：/0）

R1(config-if)#no shutdown

R1(config)#ipv6 route ::/0 Loopback0 //配置默认路由

【提示】

“ipv6 rip cisco default-information only ”命令也可以向 IPv6 RIPng 区域注入一条默认路由，但是该命令只从该接口发送默认的IPv6路由，而该接口其它的IPv6的RIPng路由都被抑制。

（2）步骤 2：配置路由器 R2

R2(config)#ipv6 unicast-routing

R2(config)#ipv6 router rip cisco

R2(config-rtr)#split-horizon

R2(config-rtr)#poison-reverse

R2(config)#interface Serial0/0/0

R2(config-if)#ipv6 address 2007:12::2/

R2(config-if)#ipv6 rip cisco enable

R2(config-if)#clock rate 128000

R2(config-if)#no shutdown

R2(config)#interface Serial0/0/1

R2(config-if)#ipv6 address 2007:23::2/

R2(config-if)#ipv6 rip cisco enable

R2(config-if)#clock rate 128000

R2(config-if)#no shutdown

（3）步骤 3：配置路由器 R3

R3(config)#ipv6 unicast-routing

R3(config)#ipv6 router rip cisco

R3(config-rtr)#split-horizon

R3(config-rtr)#poison-reverse

R3(config)#interface Serial0/0/0

R3(config-if)#ipv6 address 2007:34::3/

R3(config-if)#ipv6 rip cisco enable

R3(config-if)#clockrate 128000

R3(config-if)#no shutdown

R3(config)#interface Serial0/0/1

R3(config-if)#ipv6 address 2007:23::3/

R3(config-if)#ipv6 rip cisco enable

R3(config-if)#no shutdown

（4）步骤 4：配置路由器 R4

R4(config)#ipv6 unicast-routing

R4(config)#ipv6 router rip cisco

R4(config-rtr)#split-horizon

R4(config-rtr)#poison-reverse

R4(config)#interface Loopback0

R4(config-if)#ipv6 address 2008:4444::4/

R4(config-if)#ipv6 rip cisco enable

R4(config)#interface Serial0/0/0

R4(config-if)#ipv6 address 2007:34::4/

R4(config-if)#ipv6 rip cisco enable

R4(config-if)#no shutdown

4.实验调试

（1）show ipv6 route

R2#show ipv6 route

IPv6 Routing Table – 10 entries

Codes: C – Connected, L – Local, S – Static, R – RIP, B – BGP

U – Per-user Static route, M – MIPv6

I1 – ISIS L1, I2 – ISIS L2, IA – ISIS interarea, IS – ISIS summary

O – OSPF intra, OI – OSPF inter, OE1 – OSPF ext 1, OE2 – OSPF ext 2

ON1 – OSPF NSSA ext 1, ON2 – OSPF NSSA ext 2

D – EIGRP, EX – EIGRP external

R ::/0 [120/2]

via FE80::C800:AFF:FE90:0, Serial0/0/0

R 2006:1111::/ [120/2]

via FE80::C800:AFF:FE90:0, Serial0/0/0

C 2007:12::/ [0/0]

via ::, Serial0/0/0

L 2007:12::2/128 [0/0]

via ::, Serial0/0/0

C 2007:23::/ [0/0]

via ::, Serial0/0/1

L 2007:23::2/128 [0/0]

via ::, Serial0/0/1

R 2007:34::/ [120/2]

via FE80::C802:AFF:FE90:0, Serial0/0/1

R 2008:4444::/ [120/3]

via FE80::C802:AFF:FE90:0, Serial0/0/1

L FE80::/10 [0/0]

via ::, Null0

L FF00::/8 [0/0]

via ::, Null0

以上输出表明 R1 确实向 IPv6 RIPng 网络注入一条 IPv6 的默认路由，同时收到 3 条

IPv6 RIPng 路由条目，而且所有 IPv6 RIPng 路由条目的下一跳地址均为邻居路由器接口的

“link-local”地址。可以通过“show ipv6 rip next-hops”命令查看 RIPng 的下一跳地

址。

R2#show ipv6 rip next-hops

RIP process \"cisco\

FE80::C800:AFF:FE90:0/Serial0/0/0 [3 paths]

FE80::C802:AFF:FE90:0/Serial0/0/1 [3 paths]

（2）show ip protocols

R2#show ipv6 protocols

IPv6 Routing Protocol is \"connected\"

IPv6 Routing Protocol is \"static\"

IPv6 Routing Protocol is \"rip cisco\"

Interfaces:

Serial0/0/1

Serial0/0/0

Redistribution:

None

以上输出表明启动的 IPv6 RIPng 进程为 cisco，同时在 Serial0/0/1 和 Serial0/0/0

接口上起用 RIPng。

（3）show ipv6 rip database

该命令用来查看 RIPng 的数据库。

R2#show ipv6 rip database

RIP process \"cisco\

2006:1111::/, metric 2, installed

Serial0/0/0/FE80::C800:AFF:FE90:0, expires in 178 secs

2007:12::/, metric 2

Serial0/0/0/FE80::C800:AFF:FE90:0, expires in 178 secs

2007:23::/, metric 2

Serial0/0/1/FE80::C802:AFF:FE90:0, expires in 168 secs

2007:34::/, metric 2, installed

Serial0/0/1/FE80::C802:AFF:FE90:0, expires in 168 secs

2008:4444::/, metric 3, installed

Serial0/0/1/FE80::C802:AFF:FE90:0, expires in 168 secs

::/0, metric 2, installed

Serial0/0/0/FE80::C800:AFF:FE90:0, expires in 178 secs

以上输出显示了 R2 的 RIPng 的数据库。

（4）debug ipv6 rip

该命令用来动态查看 RIPng 的更新。

R2#debug ipv6 rip

RIP Routing Protocol debugging is on

R2#clear ipv6 route *

以上输出显示路由器 R2 发送和接收 RIPng 的信息。
