An access point that is assigned the role of bridging frames destined for or received from a secondary LAN. A designated bridge connects a secondary LAN with the primary LAN. In the access point, the secondary LAN bridge priority parameter determines if the access point is a candidate to become the designated bridge.
  • Page 345 AT-WA7500 and AT-WA7501 Installation and User’s Guide Ethernet bridging When an access point receives wireless traffic and the destination address is known, it forwards frames to the port with the shortest path to the destination address. When the access point has not learned the direction of the shortest path for the destination address, it forwards frames based on flooding settings to try to locate the destination address.
  • Page 346 Appendix C: Glossary IGMP (Internet Group Management Protocol) A standard protocol that lets you originate multiple IP tunnels using one IP multicast address. IGMP allows IP multicast frames to be routed to remote IP subnets that have hosts participating in the multicast group.
