Understanding Site Local IPv6 Addressing（本地站点地址）

【实验说明】

在R1与R2之间以太网地址上配置IPv6 site local地址，其中主机位使用 EUI-64格式地址。

【实验拓扑】

 

【实验配置步骤】

• 使用IPV6的本地站点网络地址FEC0::/64 配置R1、R2以太网接口
• R1与R2的主机部分使用 modified EUI-64 地址

 

【实验分析】

• IPv6中的 link-local, site-local, and global unicast 地址的区别？
• site-local 地址的前缀是什么？
• 什么是 EUI-64 地址，它设计的目的和作用是什么？

 

【实验配置】

R1 & R2:

interface FastEthernet0/0

ipv6 address FEC0::/64 eui-64

no shutdown

【实验验证】

R1#show ipv6 int brief

FastEthernet0/0 [up/up]

FE80::230:19FF:FE69:81A0

FEC0::230:19FF:FE69:81A0

(output omitted)

R1#show ipv6 int fastethernet0/0

FastEthernet0/0 is up, line protocol is up

IPv6 is enabled, link-local address is FE80::230:19FF:FE69:81A0

Global unicast address(es):

FEC0::230:19FF:FE69:81A0, subnet is FEC0::/64

R2#show ipv6 int brief

FastEthernet0/0 [up/up]

FE80::202:4BFF:FE51:7C00

FEC0::202:4BFF:FE51:7C00

(output omitted)

R2#show ipv6 int fastethernet0/0

FastEthernet0/0 is up, line protocol is up

IPv6 is enabled, link-local address is FE80::202:4BFF:FE51:7C00

Global unicast address(es):

FEC0::202:4BFF:FE51:7C00, subnet is FEC0::/64

Joined group address(es):

FF02::1

FF02::1:FF51:7C00

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 milliseconds

 

R1#ping ipv6 FEC0::202:4BFF:FE51:7C00

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to FEC0::202:4BFF:FE51:7C00, timeout is 2

seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/3/8 ms

R1#show ipv6 neighbors

【实验总结】

• site-local地址和IPv4中的私有地址类似，只应用在局域网中
• EUI-64 地址的来历为
