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.
