Configuration procedure
1) Configure Switch A.
# Configure an automatically generated link-local address for the interface VLAN-interface 2.
<SwitchA> system-view
[SwitchA] interface Vlan-interface 2
[SwitchA-Vlan-interface2] ipv6 address auto link-local
# Configure an EUI-64 address for the interface VLAN-interface 2.
[SwitchA-Vlan-interface2] ipv6 address 2001::/64 eui-64
# Configure a global unicast address for the interface VLAN-interface 2.
[SwitchA-Vlan-interface2] ipv6 address 3001::1/64
2) Configure Switch B.
# Configure an automatically generated link-local address for the interface VLAN-interface 2.
<SwitchA> system-view
[SwitchB] interface Vlan-interface 2
[SwitchB-Vlan-interface2] ipv6 address auto link-local
# Configure an EUI-64 address for the interface VLAN-interface 2.
[SwitchB-Vlan-interface2] ipv6 address 2001::/64 eui-64
# Configure a global unicast address for the interface VLAN-interface 2.
[SwitchB-Vlan-interface2] ipv6 address 3001::2/64
Verification
# Display the brief IPv6 information of an interface on Switch A.
[SwitchA-Vlan-interface2] display ipv6 interface vlan-interface 2
