第6章 无状态自动配置

1.R1配置

[R1]ipv6 
[R1]interface GigabitEthernet 0/0/0
[R1-GigabitEthernet0/0/0]ipv6 enable 
[R1-GigabitEthernet0/0/0]ipv6 address 2012::1 64
[R1-GigabitEthernet0/0/0]undo ipv6 nd ra halt
//开启周期性主动发送RA报文

2.R2配置

[R2]ipv6 
[R2]interface GigabitEthernet 0/0/0
[R2-GigabitEthernet0/0/0]ipv6 enable 
[R2-GigabitEthernet0/0/0]ipv6 address auto global

[R2]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:FEF9:7F0F
  Global unicast address(es):
    2012::2E0:FCFF:FEF9:7F0F,
    subnet is 2012::/64 [SLAAC 1970-01-01 00:31:27 2592000S]
  Joined group address(es):
    FF02::1:FFF9:7F0F

    FF02::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
