Objectives

Part 1: Examine the Network and Evaluate the Need for Static Routing

Part 2: Configure Static and Default Routes

Part 3: Verify Connectivity

Background

In this activity, you will configure static and default routes. A static route is a route that is entered manually by the network administrator to create a reliable and safe route. There are four different static routes that are used in this activity: a recursive static route, a directly attached static route, a fully specified static route, and a default route.

Part 1:     Examine the Network and Evaluate the Need for Static Routing

a.     Looking at the topology diagram, how many networks are there in total? _____________

b.    How many networks are directly connected to R1, R2, and R3? _________________________________

c.     How many static routes are required by each router to reach networks that are not directly connected?

____________________________________________________________________________________

d.    Test connectivity to the R2 and R3 LANs by pinging PC2 and PC3 from PC1.

Why were you unsuccessful? ____________________________________________________________

Part 2:     Configure Static and Default Routes

Step 1:     Configure recursive static routes on R1.

a.     What is recursive static route?

____________________________________________________________________________________

____________________________________________________________________________________

b.    Why does a recursive static route require two routing table lookups?

____________________________________________________________________________________

____________________________________________________________________________________

c.     Configure a recursive static route to every network not directly connected to R1, including the WAN link between R2 and R3.

d.    Test connectivity to the R2 LAN and ping the IP addresses of PC2 and PC3.

Why were you unsuccessful?

____________________________________________________________________________________

Step 2:     Configure directly attached static routes on R2.

a.     How does a directly attached static route differ from a recursive static route?

____________________________________________________________________________________

____________________________________________________________________________________

b.    Configure a directly attached static route from R2 to every network not directly connected.

c.     Which command only displays directly connected networks? ___________________________________

d.    Which command only displays the static routes listed in the routing table? _________________________

e.     When viewing the entire routing table, how can you distinguish between a directly attached static route and a directly connected network?

____________________________________________________________________________________

Step 3:     Configure a default route on R3.

a.     How does a default route differ from a regular static route?

____________________________________________________________________________________

____________________________________________________________________________________

____________________________________________________________________________________

b.    Configure a default route on R3 so that every network not directly connected is reachable.

c.     How is a static route displayed in the routing table? _________________________

Step 4:     Document the commands for fully specified routes.

Note: Packet Tracer does not currently support configuring fully specified static routes. Therefore, in this step, document the configuration for fully specified routes.

a.     Explain a fully specified route.

____________________________________________________________________________________

____________________________________________________________________________________

b.    Which command provides a fully specified static route from R3 to the R2 LAN?

____________________________________________________________________________________

c.     Write a fully specified route from R3 to the network between R2 and R1. Do not configure the route; just calculate it.

____________________________________________________________________________________

d.    Write a fully specified static route from R3 to the R1 LAN. Do not configure the route; just calculate it.

____________________________________________________________________________________

Step 5:     Verify static route configurations.

Use the appropriate show commands to verify correct configurations.

Which show commands can you use to verify that the static routes are configured correctly?

____________________________________________________________________________________ 

Part 3:     Verify Connectivity

Every device should now be able to ping every other device. If not, review your static and default route configurations.
