配置IPV6的DHCP自动获取服务器

如图配置IPv6地址
R1是DHCPv6服务器
确保 PC1和PC2自动获取IPv6地址
确保PC1和PC2互通

实现此案例需要按照如下步骤进行。

1）设置PC1和PC2的IPv6地址为“自动获取”

2）设置 SW1，确保 DHCPv6 客户端与服务器可以互通

undo terminal monitor 
system-view 
[Huawei]sysname SW1
[SW1]vlan 12              //创建 VLAN 12 
[SW1-vlan12]quit
[SW1]interface gi0/0/1        //连接 PC1所用的接口
[SW1-GigabitEthernet0/0/1]port link-type access    
[SW1-GigabitEthernet0/0/1]port default vlan  12
[SW1-GigabitEthernet0/0/1]quit
[SW1]interface GigabitEthernet 0/0/2        //连接 PC2所用的接口
[SW1-GigabitEthernet0/0/2]port link-type access    
[SW1-GigabitEthernet0/0/2]port default vlan  12
[SW1-GigabitEthernet0/0/2]quit
[SW1]interface GigabitEthernet 0/0/24        //连接 R1所用的接口
[SW1-GigabitEthernet0/0/24]port link-type access
[SW1-GigabitEthernet0/0/24]port default vlan 12
[SW1-GigabitEthernet0/0/24]quit

3）配置R1为DHCPv6服务器

undo terminal monitor 
[Huawei]sysname R1
[R1]ipv6  enable    //开启IPv6功能
[R1]interface GigabitEthernet 0/0/0    
[R1-GigabitEthernet0/0/0]ipv6 enable 
[R1-GigabitEthernet0/0/0]ipv6  address 2001:1::254/64
[R1-GigabitEthernet0/0/0]quit
[R1]dhcp enable //开启 DHCP 功能
[R1]dhcpv6 pool VLAN12             //配置IPv6 的 DHCP 地址池
[R1-dhcpv6-pool-VLAN12]address prefix 2001:1::/64    //指定IPv6的网段
[R1-dhcpv6-pool-VLAN12]excluded-address 2001:1::254 //排除IPv6地址
[R1-dhcpv6-pool-VLAN12]dns-server 240C::6666
[R1-dhcpv6-pool-VLAN12]quit
[R1]interface gi0/0/0
[R1-GigabitEthernet0/0/0]dhcpv6 server VLAN12 //在接口上关联IPv6地址池
[R1-GigabitEthernet0/0/0]quit

4）验证PC1与PC2之间的互通性

PC1>ping 2001:1::1                       //在 PC1 上访问 PC2 的IPv6地址
Ping 2001:1::1: 32 data bytes, Press Ctrl_C to break
From 2001:1::1: bytes=32 seq=1 hop limit=254 time=141 ms
