华为交换机配置DHCPv6中继示例实现为多个网段的用户分配IPv6地址

配置SwitchA作为DHCPv6中继

使能DHCP服务。

[HUAWEI] sysname SwitchA
[SwitchA] dhcp enable

配置接口GE1/0/1接口加入VLAN10，接口GE1/0/2接口加入VLAN20，接口GE1/0/3接口加入VLAN30。

[SwitchA] vlan batch 10 20 30
[SwitchA] interface gigabitethernet 1/0/1
[SwitchA-GigabitEthernet1/0/1] port link-type hybrid
[SwitchA-GigabitEthernet1/0/1] port hybrid pvid vlan 10
[SwitchA-GigabitEthernet1/0/1] port hybrid untagged vlan 10
[SwitchA-GigabitEthernet1/0/1] quit
[SwitchA] interface gigabitethernet 1/0/2
[SwitchA-GigabitEthernet1/0/2] port link-type hybrid
[SwitchA-GigabitEthernet1/0/2] port hybrid pvid vlan 20
[SwitchA-GigabitEthernet1/0/2] port hybrid untagged vlan 20
[SwitchA-GigabitEthernet1/0/2] quit
[SwitchA] interface gigabitethernet 1/0/3
[SwitchA-GigabitEthernet1/0/3] port link-type hybrid
[SwitchA-GigabitEthernet1/0/3] port hybrid pvid vlan 30
[SwitchA-GigabitEthernet1/0/3] port hybrid untagged vlan 30
[SwitchA-GigabitEthernet1/0/3] quit

配置VLANIF接口的IPv6地址。

[SwitchA] ipv6
[SwitchA] interface vlanif 10
[SwitchA-Vlanif10] ipv6 enable
[SwitchA-Vlanif10] ipv6 address fc00:1::1 64
[SwitchA-Vlanif10] quit
[SwitchA] interface vlanif 20
[SwitchA-Vlanif20] ipv6 enable
[SwitchA-Vlanif20] ipv6 address fc00:3::1 64
[SwitchA-Vlanif20] quit
[SwitchA] interface vlanif 30
[SwitchA-Vlanif30] ipv6 enable
[SwitchA-Vlanif30] ipv6 address fc00:2::1 64
[SwitchA-Vlanif30] quit

使能DHCPv6中继功能。

[SwitchA] interface vlanif 10
[SwitchA-Vlanif10] dhcpv6 relay destination fc00:3::3
[SwitchA-Vlanif10] quit
[SwitchA] interface vlanif 30
[SwitchA-Vlanif30] dhcpv6 relay destination fc00:3::3
[SwitchA-Vlanif30] quit

配置SwitchA作为网关向主机发送RA消息的M和O标志位，实现主机通过DHCPv6方式获取IPv6地址。

[SwitchA] interface vlanif 10
[SwitchA-Vlanif10] undo ipv6 nd ra halt
[SwitchA-Vlanif10] ipv6 nd autoconfig managed-address-flag
[SwitchA-Vlanif10] ipv6 nd autoconfig other-flag
[SwitchA-Vlanif10] quit
[SwitchA] interface vlanif 30
[SwitchA-Vlanif30] undo ipv6 nd ra halt
[SwitchA-Vlanif30] ipv6 nd autoconfig managed-address-flag
[SwitchA-Vlanif30] ipv6 nd autoconfig other-flag
[SwitchA-Vlanif30] quit

配置SwitchB作为DHCPv6服务器

system-view
[HUAWEI] sysname SwitchB
[SwitchB] dhcp enable
[SwitchB] ipv6
[SwitchB] vlan 20
[SwitchB-vlan20] quit
[SwitchB] interface gigabitethernet 1/0/2
[SwitchB-GigabitEthernet1/0/2] port link-type hybrid
[SwitchB-GigabitEthernet1/0/2] port hybrid pvid vlan 20
[SwitchB-GigabitEthernet1/0/2] port hybrid untagged vlan 20
[SwitchB-GigabitEthernet1/0/2] quit
[SwitchB] interface vlanif 20
[SwitchB-Vlanif20] ipv6 enable
[SwitchB-Vlanif20] ipv6 address fc00:3::3 64
[SwitchB-Vlanif20] quit
[SwitchB] dhcpv6 pool pool1
[SwitchB-dhcpv6-pool-pool1] address prefix fc00:1::/64
[SwitchB-dhcpv6-pool-pool1] excluded-address fc00:1::1
[SwitchB-dhcpv6-pool-pool1] quit
[SwitchB] dhcpv6 pool pool2
[SwitchB-dhcpv6-pool-pool2] address prefix fc00:2::/64
[SwitchB-dhcpv6-pool-pool2] excluded-address fc00:2::1
[SwitchB-dhcpv6-pool-pool2] quit
[SwitchB] dhcpv6 server preference 255
[SwitchB] ipv6 route-static :: 0 fc00:3::1
