Title: Spanning Tree

This is an extremely cut version but here goes: The first step of Spanning Tree is to Elect the Root Bridge.  Second step is that every Not Root Bridge must slect one Root port.  The third step is where loop prevention comes in, electing designated ports.  Every segment in a bridged network has one Designated Port.    Root and designated ports forward traffic, non designated block traffic.  Every active port on the root bridge is a designated port.   Hope that's clear,   Rick.  Rick Guthier CCNP/ATM Broadwing Inc. ----- Original Message ----- From: Deloso, Elmer G.

First of all, I just want to test if I'm able to post on the forum at all since I don't see any responses to my first posting. If this goes through, can someone tell me why would Spanning Tree Algorithm need a designated port when the root port has already been established as the least cost path to the Root Bridge? Thanks.
