  • Page 8: About Bridges

    1.1 About Bridges A bridge is a network device that can be used to merge two or more Local Area Networks (LANs) into a single functional LAN or, alternatively, to separate a single LAN into two or more functional LANs. The bridge is used to merge two or more LANs into a single functional LAN for: •...

    Learn Addresses When a data packet is received by the bridge, the source identifier and LAN are copied from the packet header and stored in the address cache. Then, when later packets are received, the bridge compares the destination identifier of the received packet with cache addresses. If a match is found, the bridge “knows”...

  • Page 16: Participate In "Spanning Tree

    Participate In “Spanning Tree” The spanning tree algorithm is intended to prevent LAN failure caused by the unintended generation of infinite broadcast loops. Infinite Loops Since bridges forward data packets across all LANs except the LAN from which the data packet is received, and since bridges are transparent to all other bridges, when multiple bridges connect multiple LANs, infinite loops can be generated by situations such as the following: 1.
