EE450 Fall 2006 Homework #6 Due: Tuesday, November 14 th Reading Assignment: Read Chapter 4, Sections 4.1, 4.4, 4.5 and 4.6 Text book Problems from Chapter 4: Problems 7, 8, 10, 11, 13, 15, 16, 18, 21 and 23 Supplementary Problems: 1. Construct a Spanning-tree topology computed by the spanning tree algorithm for the interconnected LAN shown below. Assume B 1 is the Root Bridge . Go through the process in detail (I am not interested in the final answer). Use the symbol “R” to indicate a “Root Port” and the Symbol “D” to indicate a “Designated Port”.

Unformatted text preview: Consider the following Bridged LAN comprising of three LANs. Assume the forwarding Tables are initially empty. Suppose the following stations transmits frames (in the following order): S 1 to S 5 , S 3 to S 2 , S 4 to S 3 , S 2 to S 1 . Clearly explain, step by step (I am not interested in final answer !!) how the forwarding tables for B 1 and B 2 are filled up with appropriate entries after the frames have been completely transmitted. Indicate the mode of operation of each bridge during each step of transmissions. S 2 B 1 B 2 S 4 LAN 1 LAN 2 S 3 S 5 LAN 3 S 1 (1) (2) (1) (2) Port Station Port Station 2...
