Understanding the Network Connection Sequence for Windows IPv6 Clients
This section describes the network connection sequence for Windows Vista/XP clients that use IPv6 addresses, and
the actions performed by the AP and controller.
1. The IPv6 client sends a Router Solicit message through the AP. The AP passes the Router Solicit message from
the IPv6 client through the GRE tunnel to the controller.
2. The controller removes the 802.11 frame and creates an 802.3 frame for the Router Solicit message.
a. The controller authenticates the user, applies firewall policies and bridges the 802.3 frame to the IPv6 router.
b. Entries are created in the user and session tables.
3. IPv6 router responds with a Router Advertisement message.
4. The controller applies firewall policies, then creates an 802.11 frame for the Router Advertisement message. The
controller sends the Router Advertisement through the GRE tunnel to the AP.
5. IPv6 client sends a Neighbor Solicitation message.
6. IPv6 router responds with a Neighbor Advertisement message.
7. If DHCP is required to provide IPv6 addresses, the DHCPv6 process is started.
8. IPv6 client sends data.
9. The controller removes the 802.11 frame and creates an 802.3 frame for the data.
The controller authenticates the user, applies firewall policies and bridges the 802.3 frame to the IPv6 router.
Entries are created in the user and session tables.
