sw1(config)#int vlan 1000
sw1(config-if-vlan1000)#ipv6 address aa::aa/64

sw1(config-if-vlan1000)#exit
sw1(config)#vlan 1001
sw1(config-vlan1001)#swi int eth1/0/4
Set the port Ethernet1/0/4 access vlan 1001 successfully
sw1(config)#int vlan 1001
sw1(config-if-vlan1001)#ipv6 address bb::bb/64
sw1(config)#int loopback 1
sw1(config-if-loopback1)#ipv6 address 11::11/128

sw1#show ipv6 int bri
