Ø 实验调试
n show ipv6 interface
该命令用来查看IPv6 的接口信息。
R1#show ipv6 interface s1/0
Serial1/0 is up, line protocol is up
IPv6 is enabled, link-local address is FE80::CE00:13FF:FEE8:0
FE80::C800:BFF:FE80:0
//本接口启用IPv6，本地链路地址自动配置
Global unicast address(es):
2007:CCCC::1, subnet is 2007:CCCC::/64
//全球聚合地址
Joined group address(es):
FF02::1
//表示本地链路上的所有节点和路由器
FF02::2
//表示本地链路上的所有路由器
FF02::1:FF00:1
//用于替换ARP 机制的被请求节点的多播地址
FF02::1:FFE8:0
//与单播地址2007:CCCC::1 相关的被请求节点多播地址

ICMP error messages limited to one every 100 milliseconds
ICMP redirects are enabled
//启用ICMP 重定向
ND DAD is enabled, number of DAD attempts: 1
//邻居发现和重复地址检测启动
ND reachable time is 30000 milliseconds
//ND 可达时间

//使用无状态自动配置地址
n show ipv6 route
该命令用来查看IPv6 路由表。
R1#show ipv6 route
IPv6 Routing Table - 9 entries
Codes: C - Connected, L - Local, S - Static, R - RIP, B - BGP
U - Per-user Static route
I1 - ISIS L1, I2 - ISIS L2, IA - ISIS interarea, IS - ISIS summary

以上输出表明路由器R1 上有一条IPv6 的静态路由，R2 上有一条IPv6 的默认路由，IPv6中的默认路由是没有“*”的。
（3）ping
R2#ping ipv6 2006:AAAA::1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2006:AAAA::1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 48/62/76 ms
实验17-2: IPv6 RIPng
Ø 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
Ø 拓扑结构
实验步骤
n 步骤1：配置路由器R1
R1(config)#ipv6 unicast-routing
R1(config)#ipv6 router rip cisco
R1(config-rtr)#split-horizon
R1(config-rtr)#poison-reverse
R1(config)#interface Serial1/0
R1(config-if)#ipv6 address 2007:12::1/64
R1(config-if)#ipv6 rip cisco enable
R1(config-if)#clockrate 128000
R1(config-if)#no shutdown
R1(config)#interface Serial1/1
R1(config-if)#ipv6 address 2007:13::1/64
R1(config-if)#ipv6 rip cisco enable
R1(config-if)#no shutdown
n 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 Serial1/0
R2(config-if)#ipv6 address 2007:12::2/64
R2(config-if)#ipv6 rip cisco enable
R2(config-if)#no shutdown
R2(config)#interface Serial1/1
R2(config-if)#ipv6 address 2007:24::2/64
R2(config-if)#ipv6 rip cisco enable
R2(config-if)#clock rate 128000
R2(config-if)#no shutdown
n 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 Loopback0
R3(config-if)#ipv6 address 2008:3333::3/64
R3(config-if)#ipv6 rip cisco enable
R3(config)#interface Serial1/1
R3(config-if)#ipv6 address 2007:13::3/64
R3(config-if)#ipv6 rip cisco enable
R3(config-if)#no shutdown
n 步骤4：配置路由器R4
R4(config)#ipv6 unicast-routing
R4(config)#ipv6 router rip cisco //启动IPv6 RIPng 进程
R4(config-rtr)#split-horizon //启用水平分割
R4(config-rtr)#poison-reverse //启用毒化反转
R4(config)#interface Loopback0
R4(config-if)#ipv6 address 2008:4444::4/64
R4(config-if)#ipv6 rip cisco enable //在接口上启用RIPng
R4(config)#interface Serial1/1
R4(config-if)#ipv6 address 2007:24::4/64
R4(config-if)#ipv6 rip cisco enable
R4(config-if)#ipv6 rip cisco default-information originate
//向IPv6 RIPng 区域注入一条默认路由（：：/0）
R4(config-if)#no shutdown
R4(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。
Ø 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
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
R ::/0 [120/2]
via FE80::CE03:11FF:FE9C:0, Serial1/1
R 2006:3333::/64 [120/3]
via FE80::CE00:11FF:FE9C:0, Serial1/0
C 2007:12::/64 [0/0]
via ::, Serial1/0
L 2007:12::2/128 [0/0]
via ::, Serial1/0
R 2007:13::/64 [120/2]
via FE80::CE00:11FF:FE9C:0, Serial1/0
C 2007:24::/64 [0/0]
via ::, Serial1/1
L 2007:24::2/128 [0/0]
via ::, Serial1/1
R 2008:4444::/64 [120/2]
via FE80::CE03:11FF:FE9C:0, Serial1/1
L FE80::/10 [0/0]
via ::, Null0
L FF00::/8 [0/0]
via ::, Null0
以上输出表明R4 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", Next Hops
FE80::CE00:11FF:FE9C:0/Serial1/0 [3 paths]
FE80::CE03:11FF:FE9C:0/Serial1/1 [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:
Serial1/1
Serial1/0
Redistribution:
None
以上输出表明启动的IPv6 RIPng 进程为cisco，同时在Serial1/1 和Serial1/0
接口上起用RIPng。
n show ipv6 rip database
该命令用来查看RIPng 的数据库。
R2#show ipv6 rip database
RIP process "cisco", local RIB

Serial1/1/FE80::CE03:11FF:FE9C:0, expires in 167 secs
以上输出显示了R2 的RIPng 的数据库。
n debug ipv6 rip
该命令用来动态查看RIPng 的更新。
R2#debug ipv6 rip
