HW2 – Router Configuration - IPv4 Static Routing and Default Routes

• This is an Individual assignment
• Objective

A router uses a routing table to determine where to send packets. The routing table contains a set of routes that describe which gateway or interface the router uses to reach a specified network. Initially, the routing table contains only directly connected networks. To communicate with distant networks, routes must be specified and added to the routing table.

In this lab, you will manually configure a static route to a specified distant network based on a next-hop IP address or exit interface. You will also configure a static default route. A default route is a type of static route that specifies a gateway to use when the routing table does not contain a path for the destination network.

Addressing Table

• Required Resources
• 2 Routers (Cisco 1941)
• 2 Switches (Cisco 2960)
• 2 PCs
• Ethernet and serial cables as shown in the topology

 

• Set Up the Topology and Initialize Devices
  • Cable the network as shown in the topology.
  • Initialize and reload the routers
    1. Write the commands used
  • Configure Basic Device Settings and Verify Connectivity

In Part 2, you will configure basic settings, such as the interface IP addresses, device access. You will verify LAN connectivity and identify routes listed in the routing tables for R1 and R3.

• Configure the PC interfaces.
• Configure basic settings on the routers.
  1. Configure device names, as shown in the Topology and Addressing Table.
  2. Disable DNS lookup. Write all the command you used including the mode.

 

1. Save the running configuration to the startup configuration file. Write all the commands you used including the mode.

• Configure IP settings on the routers.
  1. Configure the R1 and R3 interfaces with IP addresses according to the Addressing Table.
  2. The S0/0/0 (interface name may vary) connection is the DCE connection and requires the clock rate Write all the command you used including the mode.
  3. Configure loopback interfaces on R3. Write all the command you used including the mode.
• Verify connectivity of the LANs.
  1. Test connectivity by pinging from each PC to the default gateway that has been configured for that host.

From PC-A, is it possible to ping the default gateway? __________

From PC-C, is it possible to ping the default gateway? __________

1. Test connectivity by pinging between the directly connected routers.

From R1, is it possible to ping the S0/0/0 interface of R3? __________

If the answer is no to any of these questions, troubleshoot the configurations and correct the error.

1. Test connectivity between devices that are not directly connected.

From PC-A, is it possible to ping PC-C? __________

From PC-A, is it possible to ping Lo0? __________

From PC-A, is it possible to ping Lo1? __________

Were these pings successful? Why or why not?

• Gather information.

Check the status of the interfaces on R1 with the show ip interface brief command.

How many interfaces are activated on R1? __________

3. Similar to R1, check the status of the interfaces on R3. Write all the all the commands you used including the mode. Show your output (Paste a screenshot).

How many interfaces are activated on R3? __________

1. View the routing table information for R1 using the show ip route Show your output (Paste a screenshot).

What networks are present in the Addressing Table of this lab, but not in the routing table for R1?

____________________________________________________________________________________

3. View the routing table information for R3. Show your output (Paste a screenshot).

What networks are present in the Addressing Table in this lab, but not in the routing table for R3?

____________________________________________________________________________________

Why are all the networks not in the routing tables for each of the routers?

Configure Static Routes

In Part 3, you will employ multiple ways to implement static and default routes, you will confirm that the routes have been added to the routing tables of R1 and R3, and you will verify connectivity based on the introduced routes.

• Configure a recursive static route.

With a recursive static route, the next-hop IP address is specified. Because only the next-hop IP is specified, the router must perform multiple lookups in the routing table before forwarding packets. To configure recursive static routes, use the following syntax:

Router(config)# ip route network-address subnet-mask ip-address

On the R1 router, configure a static route to the 192.168.1.0 network using the IP address of the Serial 0/0/0 interface of R3 as the next-hop address. Write the command you used in the space provided.

View the routing table to verify the new static route entry. Include a screeshot
