实验拓扑：

配置过程：

R1的配置：

R1(config)#int f0/0

R1(config-if)#ipv6 address 2001:1::1/64

R1(config-if)#no shutdown

R2的配置：

R2(config)#int f0/0

R2(config-if)#ipv6 add 2001:1::2/64

R2(config-if)#no shutdown

验证及理解：

查看配置

R2#show running-config int f0/0

Building configuration...

Current configuration : 117 bytes

!

interface FastEthernet0/0

no ip address

duplex half

ipv6 address 2001:1::2/64

end

使用ping命令验证其联通性

R2#

R2#ping 2001:1::2或ping ipv6 2001:1::1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 2001:1::2, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms

R2#

查看接口情况

R2#show ipv6 int f0/0

FastEthernet0/0 is up, line protocol is up

IPv6 is enabled, link-local address is FE80::C801:EFF:FE58:0 / /本地链路地址

Global unicast address(es):

2001:1::2, subnet is 2001:1::/64 //单播地址

Joined group address(es): //加入组地址

FF02::1 //所有节点的组播地址

FF02::1:FF00:2 / /单播地址的被请求的组播地址

FF02::1:FF58:0 //本地链路的被请求组播地址

MTU is 1500 bytes

ICMP error messages limited to one every 100 milliseconds

ICMP redirects are enabled

ND DAD is enabled, number of DAD attempts: 1

ND reachable time is 30000 millisecond s

查看IPv6邻居

R2#sh ipv6 neighbors

IPv6 Address Age Link-layer Addr State Interface

2001:1::1 3 ca00.0e98.0000 STALE Fa0/0

FE80::C800:EFF:FE98:0 2 ca00.0e98.0000 STALE Fa0/0

我们在给IPV6配置多个地址的时候是没有主次地址之分的这个与IPV4不同其在配置的时候有主次之分，ipv4在配置次地址时候需要在末尾加“secondary”

例如：

R2(config)#int f0/0

R2(config-if)#ipv6 address 2001:1::2/64

R2(config-if)#ipv6 address 2001:1::3/64

R2#show running-config int f0/0

Building configuration...

Current configuration : 115 bytes

!

interface FastEthernet0/0

no ip address

duplex half

ipv6 address 2001:1::2/64

ipv6 address 2001:1::3/64

end

R2#

但是IPV6既然没有主次地址之分，那么两台路由器之间的通信采用的是哪个源地址呢？我们可以用实验来验证下

实验过程

R2#debug ipv6 packet

R2#ping 2001:1::1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 2001:1::1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 8/10/20 ms

实验证明IPV6在ping的过程中使用时ip地址较高的地址作为源地址.

二、 配置IPV6的静态路由

R1的配置：

R1(config)#int f0/0

R1(config-if)#ipv6 address 2001:1::1/64

R1(config-if)#no shutdown

R1(config)#int loopback 0

R1(config-if)#ipv6 address 2001:3::1/64

R1(config)#ipv6 unicast-routing

R2的配置：

R2(config)#int f0/0

R2(config-if)#ipv6 address 2001:1::2/64

R2(config-if)#no shutdown

R2(config)#ipv6 route 2001:3::/64 2001:1::1

R2(config)#ipv6 unicast-routing

查看ipv6路由表

R2#sh ipv6 route

R1的配置：

R1(config)#int f0/0

R1(config-if)#ipv6 address 2001:1::1/64

R1(config-if)#no shutdown

R1(config)#int loopback 0

R1(config)#ipv6 unicast-routing

R1(config)#int f0/0

R1(config-if)#ipv6 rip cisco enable

R1(config-if)#int lo 0

R1(config-if)#ipv6 rip cisco enable

R2的配置：

R2(config)#int f0/0

R2(config-if)#ipv6 address 2001:1::2/64

R2(config-if)#no shutdown

R2(config-if)#ipv6 address 2001:4::1/64

R2(config)#ipv6 unicast-routing

R2(config-rtr)#int f0/0

R2(config-if)#ipv6 rip cisco enable

R2(config-if)#int lo 0

R2(config-if)#ipv6 rip cisco enable

验证：

测试连通性

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 2001:4::1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 4/16/32 ms
