核心配置

PC:

1）配置调用dhcp

interface GigabitEthernet0/0/0

ipv6 enable  

ipv6 address auto link-local

undo ipv6 nd ra halt

ipv6 address auto dhcp

2）配置路由

ipv6 route-static :: 0 GigabitEthernet0/0/0 FE80::2E0:FCFF:FE8F:7AD4

R1:

interface GigabitEthernet0/0/0

ipv6 enable  

ipv6 address 2001:10::1/64  

ipv6 address auto link-local

undo ipv6 nd ra halt

dhcpv6 relay destination 2001:20::2

#

interface GigabitEthernet0/0/1

ipv6 enable  

ipv6 address 2001:20::1/64  

ipv6 address auto link-local

R2:

1）定义dhcpv6 地址池

dhcp enable

#

dhcpv6 pool client

address prefix 2001:10::/64

excluded-address 2001:10::1

#

2）应用地址池

interface GigabitEthernet0/0/0

ipv6 enable  

ipv6 address 2001:20::2/64  

ipv6 address auto link-local

dhcpv6 server client     //client为地址池名称

#

3）配置路由

ipv6 route-static 2001:10:: 64 GigabitEthernet0/0/0 FE80::2E0:FCFF:FE8F:7AD5
