After applying command below, error is:
[test-ar1-s7703-Vlanif200] ipv6 address 2001::100/64
Error: The configured IPv6 address conflicted with the IPv6 address or prefix of interface Tunnel94.
1. Checked configuration below:
interface Vlanif200
description IPv6
ipv6 enable
#
interface Vlanif94
description IPv6 tunnel
ip binding vpn-instance 94
ipv6 enable
ip address 2.2.2.2 255.255.255.252
#
interface Eth-Trunk94
ipv4 statistic enable both
ipv6 statistic enable both
service type tunnel
#
interface GigabitEthernet1/1/6
description ipv4 to RN for IPV6 tunnel
port link-type hybrid
port hybrid tagged vlan 94
loopback-detect enable
#
interface GigabitEthernet2/1/2
description servicee loopback interface

#
interface Tunnel94
description to HE
ip binding vpn-instance 94
ipv6 enable
ipv6 address 2001::2/64

#
ipv6 route-static vpn-instance 94 :: 0 Tunnel94
ipv6 route-static vpn-instance 94 2001:: 16 Tunnel94
#
2. Changed the subnet of VLAN 200 and retried. Displaying interface Tunnel 94 shows tunnel still down:
<Huawei>display intnterface tunnel 94
Tunnel94 current state : UP
Line protocol current state : DOWN
Description:to HE tunnebroker
Route Port,The Maximum Transmit Unit is 1500
Internet protocol processing : disabled
Encapsulation is TUNNEL, loopback not set
Tunnel source 85.11.25.102 (Vlanif94), destination unknown
Tunnel protocol/transport IPv6 over IPv4(6to4)
Current system time: 2017-12-18 14:39

Output bandwidth utilization : --
3. Tried to configure the tunnel protocol to only ipv6-ipv4 as below, then retried.
#
interface Tunnel94
description to HE
ip binding vpn-instance 94
ipv6 enable
ipv6 address 2002::2/64
tunnel-protocol ipv6-ipv4
source 2.2.2.2

4. Issue solved, interface status became UP!
[Huawei]display intnterface tunnel 94
Tunnel94 current state : UP
Line protocol current state : UP
Description:to HE tunnebroker
Route Port,The Maximum Transmit Unit is 1500
Internet protocol processing : disabled
Encapsulation is TUNNEL, loopback not set
Tunnel source 85.11.25.102 (Vlanif94), destination unknown
Tunnel protocol/transport IPv6 over IPv4(6to4)
Current system time: 2017-12-18 14:39
Input bandwidth utilization : --
Output bandwidth utilization : --
Root cause: Tunnel protocol should have been set to only ipv6-ipv4 instead of ipv6-ipv4 6to4
Solution: Set tunnel interface as below:
interface Tunnel94
ipv6 address 2002::2/64
tunnel-protocol ipv6-ipv4
