【实验说明】
在R1与R2之间配置IPv6，其中IP地址使用单播网络地址2001::/64 ，主机部分使用 modified EUI-64 格式
【实验拓扑】
【配置向导】
- 在R1与R2的以太网接口上配置 IPv6网络地址2001::/64
- 使用modified EUI-64 地址充当他们的主机为部分
【实验思考】
Pv6中的 link-local, site-local, and global unicast 地址的区别？
在整个全局单播地址空间中有多少个主机？
【实验配置】
R1 & R2:
interface FastEthernet0/0
ipv6 address 2001::/64 eui-64
【实验验证】
R1#show ipv6 interface brief
FastEthernet0/0 [up/up]
FE80::CE00:32FF:FE08:0
2001::CE00:32FF:FE08:0
R1#show ipv6 interface
FastEthernet0/0 is up, line protocol is up
IPv6 is enabled, link-local address is FE80::CE00:32FF:FE08:0
Global unicast address(es):
2001::CE00:32FF:FE08:0, subnet is 2001::/64 [EUI]
Joined group address(es):
FF02::1
FF02::2
FF02::1:FF08:0
MTU is 1500 bytes
ICMP error messages limited to one every 100 milliseconds
ICMP redirects are enabled

全球单播IPv6地址，也叫聚合全局地址，是一个以二进制序列001开头的地址，表示为2000::/3 开始的地址，整个 全球单播地址的范围为：
2000::/128 到 3FFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF/128, 可以的地址空间为
42,535,295,865,117,307,932,921,825,928,971,000,000 个，是整个ipv6 地址空间的八分之一。
