Lab 39:
Summarizing Routes with RIPv2
Lab Objective:
The objective of this lab exercise is for you to learn and understand how to summarize routes with RIPv2. Route summarization allows the size of routing tables to be reduced by advertising a summary route for a range of multiple specific routes.
Lab Purpose:
Route summarization is a fundamental skill. With the subnetted networks of today, routing tables can grow very large due to the sheer number of network entries. In order to reduce the burden of extremely large routing tables on routers, route summarization can be used. As a Cisco engineer, as well as in the Cisco CCNA exam, you will be expected to know how to configure a RIPv2 route summarization.
Certification Level:
This lab is suitable for CCNA certification exam preparation
Lab Difficulty:
This lab has a difficulty rating of 10/10
Readiness Assessment:
When you are ready for your certification exam, you should complete this lab in no more than 20 minutes
Lab Topology:
Please use the following topology to complete this lab exercise:
Task 1:
Configure the hostnames on routers R1, R2, R3 and Sw1 as illustrated in the topology.
Task 2:
Configure VLAN 2 named RIPv2-VLAN on Sw2 and assign ports FastEthernet0/1 and FastEthernet0/2 to this VLAN as access ports. Configure FastEthernet0/0 in R2 with the IP address 192.168.2.2/27 and FastEthernet0/0 on R3 with the IP address 192.168.2.3/27. Verify your VLAN and interface configuration by using ping.
Task 3:
Configure a back-to-back Serial connection between R1 and R2. Configure the DCE interface Serial0/0 in R2 to provide clocking to R1 at a clock speed of 128Kbps. Configure a back-to-back Serial connection between R2 and R3. Configure the DCE interface Serial0/1 in R2 to provide clocking to R3 at a clock speed of 128Kbps. Configure the IP addresses between R1 and R2 Serial interfaces and R2 and R3 Serial interfaces as illustrated in the topology. Ping from R1 to R2 and vice versa as well as from R2 to R3 and vice versa to validate your configuration.
Task 4:
Configure the Loopback interfaces on R1 with the IP addresses illustrated in the topology.
Task 5:
Enable RIPv2 on R1, R2 and R3 for all subnets configured on the routers. Verify that RIPv2 has been enabled using the appropriate commands. Verify that R2 and R3 can see the R1 Loopback subnets in their routing tables
Task 6:
Configure R1 to summarize the Loopback interfaces subnets and advertise a single route to R2 and R3 that encompasses the IP address range of the Loopback interfaces. Clear the routing table on R1 after you are done. Finally, validate that a summary address has been accepted and is in the RIP database.
Task 7:
Verify that both R2 and R3 now see a single route for the 10.10.0.0/24 through 10.10.3.0/24 subnets. Ping an IP address within this range from R2 and R3 to ensure that there is network connectivity.
