2. Configure Switch B:
# Configure a global unicast address for VLAN-interface 2.
<SwitchB> system-view
[SwitchB] interface vlan-interface 2
[SwitchB-Vlan-interface2] ipv6 address 3001::2/64
[SwitchB-Vlan-interface2] quit
# Configure an IPv6 static route with destination IPv6 address 2001::/64 and next hop address
3001::1.
[SwitchB] ipv6 route-static 2001:: 64 3001::1
3. Configure the host:
Enable IPv6 for the host to automatically obtain an IPv6 address through IPv6 ND.
# Display neighbor information for GigabitEthernet 1/0/2 on Switch A.
[SwitchA] display ipv6 neighbors interface gigabitethernet 1/0/2
