2. 128 eee Spanning Tree Protocol STP uses a distributed algorithm to select a bridging device STP compliant switch bridge or router that serves as the root of the spanning tree network It selects a root port on each bridging device except for the root device which incurs the lowest path cost when forwarding a packet from that device to the root device Then it selects a designated bridging device from each LAN which incurs the lowest path cost when forwarding a packet from that LAN to the root device All ports connected to designated bridging devices are assigned as designated ports After determining the lowest cost spanning tree it enables all root ports and designated ports and disables all other ports Network packets are therefore only forwarded between root ports and designated ports eliminating any possible network loops 6 23 6 System Configuration Once a stable network topology has been established all bridges listen for Hello BPDUs Bridge Protocol Data Units transmitted from the root bridge If a bridge does not get a Hello BPDU after a predefined interval Maximum Age the bridge assumes that the link to the root bridge is down This bridge will then initiate negotiations with other bridges to reconfigure the network to reestablish a valid network topology Bridge Enables disables STP on the wireless bridge or repeater Default Disabled Bridge Priority Used in selecting the root d
