(2) Wireless local area network devices with public IP address allocation function operate in the Layer 2 bridging mode and must support transparent transmission of IPv6 data packets. 

(3) The wireless local area network device with public IP address allocation function operates in the three-layer routing mode. The device can allocate IPv6 addresses to the connected users and supports the forwarding of user IPv6 data packets. 

II. Test Method for Wireless Local Area Network Devices' Support for IPv6 Protocol Capability 

Wireless local area network devices with public IP address allocation function need to undergo relevant tests. The test scenarios are as follows: Scenario 1: The home/business gateway is in three-layer routing mode, and the wireless local area network device is in two-layer bridging mode; Scenario 2: The home/business gateway is in two-layer bridging mode, and the wireless local area network device is in three-layer routing mode; Scenario 3: The optical modem is in routing mode, and the wireless local area network device is in three-layer routing mode. 

Among them, test scenarios one and two are mandatory items, while test scenario three is an optional one. 

(1) Test Scenario One 

Test environment

Home test topology 1: Three-layer routing mode of the residence/business gateway, and Layer 2 bridging mode of the wireless local area network equipment

　　The home/business gateway (optical modem) serves as the edge device of the user's network, connecting to the operator's network upwards. The home/business gateway operates in a three-layer routing mode, capable of providing dial-up access to the network and allocating IP addresses to downstream users. The wireless local area network device (the tested device) connects upwards to the home/business gateway device and downwards to the user terminal device, and operates in a two-layer bridging mode, transparently transmitting IPv6 data packets.

　　2. Test Steps

　　(1) Step 1: The home/business gateway is set up according to test topology 1. The home/business gateway is configured to operate in three-layer routing mode. On the WAN interface of the home/business gateway, user accounts and passwords are configured, and dial-up access to the operator's network is performed. On the LAN interface of the home/business gateway, the IP address allocation method for users is configured. In the IPv6 environment, any one of the SLAAC method, SLAAC DNS extension, and DHCPv6 methods can be selected.

　　(2) Step 2: Check the relevant information of the home/business gateway. The device successfully dials up, the WAN interface of the home/business gateway can be assigned an IPv6 address, and an IPv6 network prefix is provided for assigning IPv6 addresses to the LAN-side users of the home/business gateway.

　　(3) Step 3: The wireless local area network device (the device under test) is connected to the home/business gateway according to test topology 1 and configured to operate in the Layer 2 bridging mode.

　　(4) Step 4: Connect the LAN interface of the wireless local area network device using the user terminal, or access through the wireless local area network. Enable the IPv6 protocol stack on the user terminal. If the method of allocating IPv6 addresses to users is SLAAC on the home/business gateway, configure DNS on the user terminal as "2400:3200::1" or any other available IPv6 DNS; if the configuration on the home/business gateway is for other methods of allocating IPv6 addresses to users, no DNS information needs to be configured on the user terminal.

　　(5) Step 5: Check whether the user terminal has obtained IPv4 and IPv6 addresses.

　　(6) Step 6: Access websites that support IPv4 and those that support IPv6 through the user terminal, and observe the access status.

　　3. Expected Results

　　In step five, the user terminal is able to obtain IPv4 and IPv6 addresses, and the network prefix of these addresses is consistent with the configuration information of the home/enterprise gateway.

　　(2) In step six, the user terminal successfully accessed websites that support both IPv4 and IPv6.

　　4. Criteria for Judgment

　　The results are in line with expectations. The wireless local area network equipment passed the IPv6 functionality test in test scenario one; otherwise, it failed.

The home/business gateway operates in the three-layer routing mode. The wireless local area network device (the tested device) connects to the home/business gateway device on the upper side and to the user terminal device on the lower side, also operating in the three-layer routing mode. The wireless local area network device defaults to using the IPv6 protocol and assigns IP addresses to downstream user devices.

　　2. Test Steps

The home/business gateway is configured to work in this mode, and on the WAN interface of the home/business gateway, user accounts, passwords, and dial-up access to the operator's network are configured. On the LAN interface of the home/business gateway, the IP address allocation method for users is configured. In the IPv6 environment, any one of the SLAAC method, SLAAC DNS extension, and DHCPv6 methods can be selected.

　　(2) Step 2: After the wireless local area network device (the device under test) is powered on and started, use the management tool/management address of the wireless local area network device to check the default configuration of the wireless local area network device and determine whether the IPv6 protocol is enabled by default.

　　(3) Step 3: The wireless local area network devices are connected to the home/business gateway according to the test topology 3 and configured to operate in the three-layer routing mode. On the WAN interface of the wireless local area network devices, IPv6 forwarding is configured, such as NPTv6 or IPv4/6 dual-channel, etc.; on the LAN interface of the wireless local area network devices, the user-oriented IP address allocation method is configured. In the IPv6 environment, any one of the SLAAC method, SLAAC DNS extension and DHCPv6 methods can be selected.

　　(4) Step 4: Connect the LAN interface of the wireless local area network device using the user terminal, or access through the wireless local area network. Enable the IPv6 protocol stack on the user terminal. If the method of allocating IPv6 addresses to users on the wireless local area network device is SLAAC, configure DNS on the user terminal as "2400:3200::1" or any other available IPv6 DNS; if the configuration on the wireless local area network device is for other methods of allocating IPv6 addresses to users, no DNS information needs to be configured on the user terminal.

　　(5) Step 5: Check whether the user terminal has obtained IPv4 and IPv6 addresses.

　　(6) Step 6: Access websites that support IPv4 and those that support IPv6 through the user terminal, and observe the access status.

　　3. Expected Results

　　(2) In Step 2, after the wireless local area network device is powered on and initialized, the IPv6 protocol stack should be enabled by default and no additional configuration is required.

　　(2) In step five, the user terminal can obtain IPv4 addresses, IPv6 addresses, the network prefixes of both IPv4 and IPv6 addresses, and the configuration information of the wireless local area network device is consistent.

　　(3) In Step 6, the user terminal was able to access websites that support IPv4 successfully; websites that support IPv6 also succeeded.

　　4. Criteria for Judgment

　　The results are in line with expectations. The wireless local area network equipment passed the IPv6 functionality test in test scenario three; otherwise, it failed.
