第3章 EUI-64的方式形成的地址

1.查看R1接口的MAC地址

<R1>display interface GigabitEthernet 0/0/0 
GigabitEthernet0/0/0 current state : UP
Line protocol current state : DOWN
Description:HUAWEI, AR Series, GigabitEthernet0/0/0 Interface
Route Port,The Maximum Transmit Unit is 1500
Internet protocol processing : disabled
IP Sending Frames' Format is PKTFMT_ETHNT_2, Hardware address is 00e0-fc3f-49de

2.查看R1本地接口的IPV6 link-local地址，在MAC地址的OUI与厂商之间插入16bit的FFFE，变成00e0-fcff–fe3f-49de，根据EUI-64形成IPV6接口的规则。

1）EUI-64地址第一个字节的第七位反转得到：02e0-fcff--fe3f-49de
2）加上固定前缀FE80得到本接口link-local地址：FE80::2E0:FCFF:FE3F:49DE
<R1>display ipv6 interface GigabitEthernet 0/0/0 
GigabitEthernet0/0/0 current state : UP 
IPv6 protocol current state : UP
IPv6 is enabled, link-local address is FE80::2E0:FCFF:FE3F:49DE

3.使用EUI-64形成全局的地址

[R1]interface GigabitEthernet 0/0/0
[R1-GigabitEthernet0/0/0]ipv6 address 2011::/64 eui-64
[R1]display ipv6 interface GigabitEthernet 0/00/
                                           ^
Error: Wrong parameter found at '^' position.
[R1]display ipv6 interface GigabitEthernet 0/0/0
GigabitEthernet0/0/0 current state : UP 
IPv6 protocol current state : UP
IPv6 is enabled, link-local address is FE80::2E0:FCFF:FE3F:49DE
  Global unicast address(es):
    2012::1, subnet is 2012::/64
    2011::2E0:FCFF:FE3F:49DE, subnet is 2011::/64
  Joined group address(es):
    FF02::1:FF3F:49DE
    FF02::2
    FF02::1
    FF02::1:FF00:1
  MTU is 1500 bytes
  ND DAD is enabled, number of DAD attempts: 1
  ND reachable time is 30000 milliseconds
  ND retransmit interval is 1000 milliseconds
  Hosts use stateless autoconfig for addresses
