Configure Switch as a DHCPv6 relay agent:
1.
# Enable the IPv6 packet forwarding function.
<Switch> system-view
[Switch] ipv6
# Configure the IPv6 addresses of VLAN-interface 2 and VLAN-interface 3 respectively.
[Switch] interface vlan-interface 2
[Switch-Vlan-interface2] ipv6 address 2::1 64
[Switch-Vlan-interface2] quit
[Switch] interface vlan-interface 3
[Switch-Vlan-interface3] ipv6 address 1::1 64
# Enable DHCPv6 relay agent and specify the DHCPv6 server address on VLAN-interface 3.
[Switch-Vlan-interface3] ipv6 dhcp relay server-address 2::2
Configure Switch as a gateway:
2.
# Enable Switch to send RA messages and turn on the M and O flags.
[Switch-Vlan-interface3] undo ipv6 nd ra halt
[Switch-Vlan-interface3] ipv6 nd autoconfig managed-address-flag
[Switch-Vlan-interface3] ipv6 nd autoconfig other-flag

Verifying the configuration
