Introduction

In this practice Packet Tracer Skills Exam, you will:

finish the configuration of a partially configured network

establish connectivity to the East Region and the Internet through the use of static and dynamic routing

Note: The password for user EXEC mode is cisco. The password for privileged EXEC mode is class.

Step 1: Finish the IP Addressing.

Note: Initially, you can only access router W-Branch2 through the console connection on NetAdmin.

a. Configure and verify interface addressing on W-Branch2.

Configure and activate all interfaces for W-Branch2 that are listed in the addressing table.

b. Configure the correct IP addresses on WPC2 and W-Branch1.

Configure WPC2 with the last IP address in the subnet.

Configure the Fa0/1 interface on W-Branch1 with the last IP address in the subnet.

c. Verify connectivity.

Step 2: Discover the Network.

Explore the network to determine the IP addressing of the serial interfaces that WestHQ shares with W-Branch1 and W-Branch2.

Remotely access WestHQ.

Step 3: Configure Static and Default Routing.

a. Configure connectivity to the East Region.

Using the next hop address 192.0.0.2, configure one summary static route on WestHQ for the entire East Region. The East Region subnets are listed in the following table:

East Region Subnets

192.168.0.0/25

192.168.0.128/25

192.168.1.0/26

192.168.1.64/26

192.168.1.128/26

192.168.1.192/27

192.168.1.224/28

192.168.1.240/30

192.168.1.244/30

192.168.1.248/30

192.168.1.252/30

Configure a default route on WestHQ to send to the Internet all other traffic for destinations that are not found in the WestHQ routing table. Use the outbound interface argument.

b. Verify static and default routing.

Step 4: Configure OSPF Routing.

a. Configure OSPF on WestHQ, W-Branch1, and W-Branch2.

Use OSPF process ID 1 and area 0.

Advertise each subnet individually with its corresponding wildcard mask. On WestHQ, do not advertise the subnet to the Internet or the subnet to East Region.

Disable OSPF updates out interfaces where there are no OSPF neighbors available.

Configure WestHQ to send the default route to W-Branch1 and W-Branch2 in OSPF updates.

b. Modify the default OSPF operation.

Configure W-Branch1 to always be the DR by using a priority of 100.

Configure W-Branch2 to always be the BDR by using a priority of 50.

Change the hello interval to 20 seconds on W-Branch1 and W-Branch2 for the LAN that these two routers share with ServerFarm.

Verify OSPF neighbor status.

c. Verify that OSPF is fully operational.

Verify that the routing tables on W-Branch1, W-Branch2, and WestHQ contain all the expected routes. It may be necessary to shutdown and then reactivate interfaces to force OSPF to converge.

Step 5: Verify Full Connectivity.

Although these are not scored, the following connectivity tests should be successful.

To test the static route to East Region, successfully ping between WestHQ and EPC1.

To test the OSPF neighbor establishment with ServerFarm, successfully ping between WPC1 and Payroll.

To test end-to-end connectivity between the East and West Regions, successfully ping between WPC2 and EPC3.

To test the default route, successfully ping the Cisco Server from NetAdmin.
