APPENDIX E " OWL/IP

Following are three primary differences between secondary LANs separated by wireless links and secondary LANs separated by OWL/IP tunnels:

"Any access point on the distribution LAN can provide wireless connectivity for a designated bridge on a secondary Ethernet LAN. Only the super root can originate OWL/IP connections to designated bridges on remote subnets.

"Flooding parameters for designated bridges on secondary Ethernet LANs can be adjusted through the global settings in the super root, or through local configuration in the designated bridge. Flooding parameters for OWL/IP tunnels are not adjustable.

"The super root and designated bridges for OWL/IP tunnels include additional configurable output (transmit) filters, allowing frame types forwarded through tunnels to be tightly controlled. These filters are provided in addition to the standard Ethernet input filters available in all access points.

Tunnel Origination

Building the Spanning Tree

The open wireless LAN spanning tree is established and maintained by short hello messages originating at the super root. “Hellos” are broadcast periodically at intervals of a few seconds. These frames contain network coordination information, including root priority.

At power up, all super root candidates listen for hello messages. If they do not detect hellos, or detect hellos from a lower priority root candidate, they begin to send hello messages.
