第7章 有状态自动配置

7.1 有状态自动配置

1.R1配置

[R1]ipv6 
[R1]dhcp enable 
[R1]dhcpv6 poo dsrw
[R1-dhcpv6-pool-dsrw]address prefix 2012::/64
[R1-dhcpv6-pool-dsrw]dns-domain-name dsrw.com
[R1-dhcpv6-pool-dsrw]dns-server 2002::2

[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]ipv6 nd autoconfig managed-address-flag 
//设置M位位置为1
[R1-GigabitEthernet0/0/0]ipv6 nd autoconfig other-flag 
//设置O位置为1
[R1-GigabitEthernet0/0/0]dhcpv6 server dsrw
//调用pool

2.R2配置

[R2]ipv6 
[R2]dhcp enable
[R2]interface GigabitEthernet 0/0/0
[R2-GigabitEthernet0/0/0]ipv6 address auto link-local
[R2-GigabitEthernet0/0/0]ipv6 address auto dhcp

3.R2查看地址

[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::3, subnet is 2012::3/128
  Joined group address(es):
    FF02::1:FF00:3
    FF02::2
    FF02::1
    FF02::1:FFF9:7F0F
  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
