Packet Tracer
Activity
Open your LSG02-0903-task2.pka saved version of this Packet Tracer Exercise. According to your
answers to the questions in the “Modifying the Bandwidth” exercise, complete the steps in Task 3.
Task 3: Modify the EIGRP Metric
Modify the bandwidth on interfaces HQ shares with Branch routers.
Step 1.
Modify the bandwidth on the interface B1 shares with HQ.
Step 2.
Modify the bandwidth on the interface B2 shares with HQ.
Step 3.
Modify the bandwidth on the interface B3 shares with HQ.
Step 4.
Your completion percentage should be 83%. If not, review the previous steps to see what
part of the task you left incomplete.
DUAL
The following sections review the concepts of how DUAL determines the best loop-free path and
loop-free backup paths.

Successor and Feasible Distance
Briefly explain the term
successor
.
A successor is a neighboring router that is used for packet forwarding and is the least-cost route to the
destination network.
Briefly explain what is meant by
feasible distance
.
Feasible distance (FD) is the lowest calculated metric to reach the destination network.
Examine the routing table for HQ in Example 9-4 and answer the questions that follow.
