Verifying the EIGRP Database

Verifying the EIGRP Database

Lab Objective:

The objective of this lab exercise is for you to learn and understand how to verify the EIGRP database using the appropriate Cisco IOS commands.

Lab Purpose:

Verifying the EIGRP database is a fundamental skill. EIGRP is an advanced Distance Vector protocol that incorporates features from both Distance Vector and Link State routing protocols. The EIGRP database is a feature of Link State routing protocols. As a Cisco engineer, as well as in the Cisco CCNA exam, you will be expected to know how to verify routes in the EIGRP database.

Certification Level:

This lab is suitable for CCNA certification exam preparation

Lab Difficulty:

This lab has a difficulty rating of 6/10

Readiness Assessment:

When you are ready for your certification exam, you should complete this lab in no more than 10 minutes

Lab Topology:

Please use the following topology to complete this lab exercise:

Task 1:

Configure the hostnames on routers R1 and R3, as illustrated in the topology. Since R1 S0/0 is the DCE end of the back-to-back Serial connection, configure R1 to send R3 clocking information at a rate of 256Kbps. Configure the IP addresses for R1 and R3 S0/0 interfaces as specified in the topology and ping between the routers to verify connectivity based on your configuration.

Task 2:

Configure the Loopback interfaces on R3 as illustrated in the topology.

Task 3:

Enable EIGRP using Autonomous System 172 on both R1 and R3 and configure EIGRP network statements for R1 and R3 S0/0 interfaces and for the Loopback interfaces on R3. Ensure that EIGRP does not perform automatic summarization at Classful network boundaries.

Task 4:

On R1, verify the state of the received routes in the EIGRP database using the appropriate show commands. To take a more detailed look, also verify the EIGRP database information of the 10.20.20.0/24 subnet.
