Routers should be configured with a default route
You need to identify all the problems with the settings in each router, the impact on the
network due to the problems and how you can rectify them.
You need to implement your proposed solutions in the given packet tracer file.
IP addresses of the router interfaces are NOT to be changed.
HQ Tech Router
HQ LVL1 Router
HQ LVL2 Router
B. Complaints from Staff ()
You need to identify all the causes associated with the complaints shown in the table below
and how you can rectify them. You do NOT need to mention any issues related to the
