Introduction

The following information provides an example for configuring IPv6 access.

Prerequisites

This document applies to Comware 7-based access points. Procedures and information in the examples might be slightly different depending on the software or hardware version of the access points.

The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

This document assumes that you have basic knowledge of DHCPv6, WLAN authentication, and WLAN access.

Example: Configuring IPv6 access

Network configuration

As shown in Figure 1, the clients associate with the fat AP to access the network. Configure the fat AP to act as a DHCP server to assign addresses to client 1 and assign a prefix in prefix range 3001::/64 to client 2. Make sure the following requirements are met:

·     Client 1 joins VLAN 200 and client 2 joins VLAN 300.

·     The WLAN uses IPv6 addresses.

Procedures

1.     Configure VLAN interfaces:

# Create VLAN 200 and VLAN-interface 200, and assign an IP address to the VLAN interface. Client 1 will join this VLAN after coming online.

<FAT AP> system-view  

[FAT AP] vlan 200

[FAT AP-vlan200] quit

[FAT AP] interface vlan-interface 200

[FAT AP-Vlan-interface200] ipv6 address 2001::1/64

[FAT AP-Vlan-interface200] quit

# Create VLAN 300 and VLAN-interface 300, and assign an IP address to the VLAN interface. Client 2 will join this VLAN after coming online.

[FAT AP] vlan 300

[FAT AP-vlan300] quit

[FAT AP] interface vlan-interface 300

[FAT AP-Vlan-interface430] ipv6 address 3001::1/64

[FAT AP-Vlan-interface300] quit

2.     Configure the DHCPv6 service:

# Enable the DHCPv6 server on the VLAN interfaces.

[FAT AP] interface vlan-interface 200

[FAT AP-Vlan-interface200] ipv6 dhcp select server

[FAT AP-Vlan-interface200] quit

[FAT AP] interface vlan-interface 300

[FAT AP-Vlan-interface300] ipv6 dhcp select server

[FAT AP-Vlan-interface300] quit

# Disable RA message suppression, and set both the managed address configuration flag (M) and the other stateful configuration flag (O) to 1 in RA advertisements to be sent.

[FAT AP] interface vlan-interface 200

[FAT AP-Vlan-interface200] undo ipv6 nd ra halt

[FAT AP-Vlan-interface200] ipv6 nd autoconfig managed-address-flag

[FAT AP-Vlan-interface200] ipv6 nd autoconfig other-flag

[FAT AP-Vlan-interface200] quit

[FAT AP] interface vlan-interface 300

[FAT AP-Vlan-interface300] undo ipv6 nd ra halt

[FAT AP-Vlan-interface300] ipv6 nd autoconfig managed-address-flag

[FAT AP-Vlan-interface300] ipv6 nd autoconfig other-flag

[FAT AP-Vlan-interface300] quit

# Create a DHCPv6 address pool 1, and specify subnet 2000::0/64. The fat AP will use this address pool to assign addresses to client 1.

[FAT AP] ipv6 dhcp pool 1

[FAT AP-dhcp6-pool-1] network 2000::0/64

[FAT AP-dhcp6-pool-1] quit

# Create prefix pool 1, and specify prefix 3001::/64 with an assigned prefix length of 64.

[FAT AP] ipv6 dhcp prefix-pool 1 prefix 3001::/64 assign-len 64

# Create a DHCPv6 address pool 2, and specify gateway address 3001::1. The fat AP will use this address pool to assign addresses to client 2.

[FAT AP] ipv6 dhcp pool 2

[FAT AP-dhcp6-pool-2] gateway-list 3001::1

# Apply prefix pool 1 to address pool 2.

[FAT AP-dhcp6-pool-2] prefix-pool 1

[FAT AP-dhcp6-pool-2] quit

3.     Configure wireless services:

# Create service template 1 and enter its view.

[FAT AP] wlan service-template 1

# Configure the SSID as service1.

[FAT AP-wlan-st-1] ssid service1

# Specify VLAN 200 for the service template.

[FAT AP-wlan-st-1] vlan 200

# Enable the service template.

[FAT AP-wlan-st-1] service-template enable

# Enable snooping DHCPv6 packets and snooping ND packets.

[FAT AP-wlan-st-1] client ipv6-snooping dhcpv6-learning enable

[FAT AP-wlan-st-1] client ipv6-snooping nd-learning enable

[FAT AP-wlan-st-1] quit

# Create service template 2 and enter its view.

[FAT AP] wlan service-template 2

# Configure the SSID as service2.

[FAT AP-wlan-st-2] ssid service2

# Specify VLAN 300 for the service template.

[FAT AP-wlan-st-2] vlan 300

# Enable the service template.

[FAT AP-wlan-st-2] service-template enable

# Enable snooping DHCPv6 packets and snooping ND packets.

[FAT AP-wlan-st-2] client ipv6-snooping dhcpv6-learning enable

[FAT AP-wlan-st-2] client ipv6-snooping nd-learning enable

[FAT AP-wlan-st-2] quit

4.     Bind service templates to radio interfaces:

# Enter interface view of interface WLAN-Radio 1/0/1.

[FAT AP] interface wlan-radio 1/0/1

# Bind service template 1 to interface WLAN-Radio 1/0/1.

[FAT AP-WLAN-Radio1/0/1] service-template 1

# Bind service template 2 to interface WLAN-Radio 1/0/1.

[FAT AP-WLAN-Radio1/0/1] service-template 2

[FAT AP-WLAN-Radio1/0/1] quit

Verifying the configuration

# Verify that client 1 and client 2 can access the IPv6 WLAN successfully.
