Packet Tracer - Troubleshoot Static and Default Routes
Background / Scenario
A newly hired network technician is attempting to preconfigure a simple topology that will be delivered to a customer. The technician has not been able to establish connectivity between the three LANs. You have been
asked to troubleshoot the topology and verify connectivity between the hosts on the three LANs over IPv4 and
IPv6.
Instructions
Step 1: Locate and document the problems.
Record your findings in a table like the one below.
Location
Problem
Solution
R3
IPv6 route to LAN1 missing
Configure ipv6 route to lan1: 2001:db8:1::/64
R3
Ipv4 mask incorrect
Correct mask: 255.255.255.128
R1
Ipv4 default route next hop should be 172.31.1.193
Reconfigure to correct address: 172.31.1.193
R2
Ipv4 next hop addresses are backwards
Reverse addresses
R2
Ipv6 route to LAN1 destination incorrectly addressed
Correct address: 2001:db8:1::/64
Step 2: Repair the problems.
Configure the devices so that full connectivity exists between the hosts on the LANs over IPv4 and IPv6.
Note:
Your task is to establish connectivity using the existing static route design. Changing the types of static routes used will result in a loss of points.
