RIPv2 Basics 2

RIP Version 2 (RIPv2) configuration requires the use of network command to indirectly enable RIP on router interfaces. This lab asks you to configure RIP by choosing the correct parameters for the RIPv2 network command, please consider a few other RIP options. And RIPv2 is easily the single largest new topic added into ICND1 (CCENT) with Cisco’s May 2016 exam changes.

Requirements

This lab exercise uses a topology with four routers at the same site all connected to the same layer 2 Ethernet VLAN. The lab begins with the four routers having their interfaces up and working and with IPv4 addresses configured. Your job: look at the design details and choose the correct RIP Version 2 (RIPv2) configuration to match the design. The specific rules for this lab are:

• Use RIP Version 2 only
• Do not automatically summarize routes at the boundary between classful networks
• Use only the required commands
• Assumptions:
  • All router interfaces shown in the lab are up and working
  • All router interfaces have been pre-configured with the IPv4 addresses shown in the figure
  • All LAN switches in the figure are layer 2 switches

Initial Configuration

Examples 1, 2, 3 and 4 show the beginning configuration state of R1, R2, R3 and R4.

Example 1: R1 Config

hostname R1
!
interface GigabitEthernet0/1
 no shutdown
 ip address 192.168.100.1 255.255.255.0
!
interface GigabitEthernet0/2
 no shutdown
 ip address 192.168.1.1 255.255.255.0

Example 2: R2 Config

hostname R2
!
interface GigabitEthernet0/1
 no shutdown
 ip address 192.168.100.2 255.255.255.0
!
interface GigabitEthernet0/2
 no shutdown
 ip address 192.168.2.1 255.255.255.0

Example 3: R3 Config

hostname R3
!
interface GigabitEthernet0/1
 no shutdown
 ip address 192.168.100.3 255.255.255.0
!
interface GigabitEthernet0/2
 no shutdown
 ip address 192.168.3.1 255.255.255.0

Example 4: R4 Config

hostname R4
!
interface GigabitEthernet0/1
 no shutdown
 ip address 192.168.100.4 255.255.255.0
!
interface GigabitEthernet0/2
 no shutdown
 ip address 192.168.4.1 255.255.255.0

Answer on Paper, or Maybe Test in Lab

Next, write your answer on paper. Or if you have some real gear, or other tools, configure the lab with those tools.

To test your solution if you happen to try it with VIRL or real gear, you can check by going to each of the routers and attempt to ping both of the other routers. This can then be extended by using an extended ping (or traceroute) from each of the routers using a source interface of each respective Loopback0 interface.

Do this Lab with Cisco’s VIRL

You can do these labs on paper and still get a lot out of the lab. As an extra help, we have added files for the Virtual Internet Routing Lab (VIRL) software as well. The .VIRL file found here is a file that when used with VIRL will load a lab topology similar to this lab’s topology, with the initial configuration shown in the lab as well. This section lists any differences between the lab exercise and the .VIRL file’s topology and configuration.

All interfaces in topology match the lab figure.
