SECTION 4 " Configuration

OWL/IP Options

"NOTE: Appendix E provides additional information about OWL/IP and contains configuration examples.

Overview

The OWL/IP extension to the open wireless LAN architecture enables a wireless LAN installation to span multiple IP subnets. OWL/IP is an advanced capability that requires basic knowledge of IP addressing conventions and routing to configure and use. You should review the following pages and Appendix E before using this capability.

OWL/IP does the following:

"Enables access points on different IP subnets to belong to the same wireless network.

"Supports transparent roaming of wireless stations between access points on different subnets without losing network connections for:

"Wireless stations using Internet Protocol (IP).

"Wireless stations using other network protocols, such as NORAND Network Layer (NNL), that are normally not routable.

OWL/IP is activated by enabling the OWL/IP port in the access point. The port is an entryway to an IP tunnel originated by the super root on the home subnet, and terminated by a designated bridge operating on a remote subnet (Figure 4-5). Frames forwarded through the tunnel are encapsulated using the Generic Router Encapsulation (GRE) protocol running over IP.
