Vista has two paths to network , but they have unequal IGRP metrics. You will configure unequal-cost load balancing and use advanced debug features to verify your work. | Unequal-Cost Load Balancing with IGRP Workstation 24 SanJose2 SanJose1 IGRP 36 Vista Fa0 0 24 S0 0 24 S0 1 24 Fractional T1 56 Kbps Fractional T1 384 Kbps S0 0 24 S0 1 24 Fa0 0 24 Fa0 0 24 Objective In this lab you observe unequal-cost load balancing on an IGRP network by using advanced debug commands. Scenario Vista has two paths to network but they have unequal IGRP metrics. You will configure unequal-cost load balancing and use advanced debug features to verify your work. Step 1 Build and configure the network according to the diagram just shown. Use IGRP with an autonomous system number of 36 and enable updates on all active interfaces with these network commands SanJose2 config router igrp 36 SanJose2 config-router network SanJose2 config-router network 1 - 3 Semester 5 Advanced Routing - Lab Copyright 2001 Cisco Systems Inc. Use ping to verify your work and test connectivity between all interfaces. Also because IGRP s metric includes bandwidth in its calculation you must manually configure the bandwidth of serial interfaces in order to ensure accuracy. For the purposes of this lab Vista s alternative paths to network aren t of unequal cost until the appropriate bandwidths are set. Use the following commands to further configure Vista for the correct bandwidth and process switching Vista config interface s0 0 Vista config-if bandwidth 56 Vista config-if no ip route-cache Vista config-if interface s0 1 Vista config-if bandwidth 384 Vista config-if no ip route-cache Use the show interface command output to verify the correct bandwidth settings and the show ip interface command to ensure that fast switching is disabled. 1. Can the bandwidth of Ethernet or Token Ring interfaces be set manually 2. Can an Ethernet interface be placed in fast switching mode Step 2 Check the routing table on Vista by using the show ip route
