CCNA Certification – RIPv2 Configuration Lab Simulation

Lab Simulation Question – RIPv2


Central Florida Widgets recently installed a new router in their office. Complete the network installation by performing the initial router configurations and configuring RIPV2 routing using the router command line interface (CLI) on the R2.
Configure the router per the following requirements:
– Name of the router is R2
– Enable.secret password is cisco
– The password to access user EXEC mode using the console is cisco2
– The password to allow telnet access to the router is cisco3
IPV4 addresses mast be configured as follows:
– Ethernet network 209.165.201.0/27 – router has fourth assignable host address in subnet
– Serial network is 192.0.2.176/28 – router has last assignable host address in the subnet.
– Interfaces should be enabled.
– Router protocol is RIPV2

Attention:

In practical examinations, please note the following, the actual information will prevail.
1. Name or the router is xxx
2. EnablE. secret password is xxx
3. Password In access user EXEC mode using the console is xxx
4. The password to allow telnet access to the router is xxx
5. IP information

Answer:

Step 1:

Click on the console host, you will get a pop-up screen CLI of Router.

Configure the new router as per the requirements provided in Lab question
Requirement 1:
Name of the router is R2

Step 2:

To change the hostname of the router to R2 follow the below steps:

Router>
Router>enable
Router#configure terminal
Router(config)#hostname R2
R2(config)#

Requirement 2:
Enable-secret password is cisco1

Step 3:

To set the enable secret password to cisco1 use the following command

R2(config)#enable secret cisco1

Requirement 3:
The password to access user EXEC mode using the console is cisco2

Step 4:

We need to configure the line console 0 with the password cisco2
Also remember to type login command after setting up the password on line con 0 which allows router to accept logins via console.

R2(config)#line con 0
R2(config-line)#password cisco2
R2(config-line)#login
R2(config-line)#exit

Requirement 4:
The password to allow telnet access to the router is cisco3

Step 5:

To allow telnet access we need to configure the vty lines 0 4 with the password cisco3
Also remember to type login command after setting up the password on line vty 0 4 which allows router to accept logins via telnet.

R2(config)#line vty 0 4
R2(config-line)#password cisco3
R2(config-line)#login
R2(config-line)#exit

Requirement 5:
(5.1) Ethernet network 209.165.201.0 /27 – Router has the fourth assignable host address in subnet.
(5.2) Serial Network is 192.0.2.176 /28 – Router has the last assignable host address in subnet.

Step 6:

Ethernet network 209.165.201.0 /27 – Router has the fourth assignable host address in subnet.
Ethernet Interface on router R2 is Fast Ethernet 0/0 as per the exhibit
First we need to identify the subnet mask
Network: 209.165.201.0 /27
Subnet mask: /27: 27 bits = 8 + 8 + 8 + 3
=8(bits).8(bits).8(bits) .11100000 (3bits)
=255.255.255.11100000
=11100000 = 128+64+32+0+0+0+0+0
= 224
Subnet mask: 255.255.255.224
Different subnet networks and there valid first and last assignable host address range for above subnet mask are

Subnet Networks Valid Host address range Broadcast address
209.165.201.0 209.165.201.1 – 209.165.201.30 209.165.201.31
209.165.201.32 209.165.201.33 – 209.165.201.62 209.165.201.63
209.165.201.64 209.165.201.65 – 209.165.201.94 209.165.201.95
209.165.201.96 209.165.201.97 – 209.165.201.126 209.165.201.127
209.165.201.128 209.165.201.129 – 209.165.201.158 209.165.201.159
209.165.201.160 209.165.201.161 – 209.165.201.190 209.165.201.191
209.165.201.192 209.165.201.193 – 209.165.201.222 209.165.201.223
209.165.201.224 209.165.201.225 – 209.165.201.254 209.165.201.255

Use above table information for network 209.165.201.0 /27 to identify
First assignable host address: 209.165.201.1
Last assignable host address: 209.165.201.30
Fourth assignable host address: 209.165.201.4
This IP address (209.165.201.4) which we need to configure on Fast Ethernet 0/0 of the router using the subnet mask 255.255.255.224

R2(config)#interface fa 0/0
R2(config-if)#ip address 209.165.201.4 255.255.255.224

Requirement 6:
To enable interfaces
Use no shutdown command to enable interfaces

R2(config-if)#no shutdown
R2(config-if)#exit
Step 7:

Serial Network is 192.0.2.176 /28 – Router has the last assignable host address in subnet.
Serial Interface on R2 is Serial 0/0/0 as per the exhibit
First we need to identify the subnet mask
Network: 192.0.2.176 /28
Subnet mask: /28: 28bits = 8bits+8bits+8bits+4bits
=8(bits).8(bits).8(bits) .11110000 (4bits)
=255.255.255.11100000
=11100000 = 128+64+32+16+0+0+0+0
= 240
Subnet mask: 255.255.255.240
Different subnet networks and there valid first and last assignable host address range for above subnet mask are

Subnet Networks Valid Host address range Broadcast address
192.0.2.0 192.0.2.1 – 192.0.2.14 192.0.2.15
192.0.2.16 192.0.2.17 – 192.0.2.30 192.0.2.31
192.0.2.32 192.0.2.33 – 192.0.2.46 192.0.2.47
192.0.2.48 192.0.2.49 – 192.0.2.62 192.0.2.64
192.0.2.64 192.0.2.65 – 192.0.2.78 192.0.2.79
192.0.2.80 192.0.2.81 – 192.0.2.94 192.0.2.95
192.0.2.96 192.0.2.97 – 192.0.2.110 192.0.2.111
192.0.2.112 192.0.2.113 – 192.0.2.126 192.0.2.127
192.0.2.128 192.0.2.129 – 192.0.2.142 192.0.2.143
192.0.2.144 192.0.2.145 – 192.0.2.158 192.0.2.159
192.0.2.160 192.0.2.161 – 192.0.2.174 192.0.2.175
192.0.2.176 192.0.2.177 – 192.0.2.190 192.0.2.191

Use above table information for network 192.0.2.176 /28 to identify
First assignable host address: 192.0.2.177
Last assignable host address: 192.0.2.190
We need to configure Last assignable host address (192.0.2.190) on serial 0/0/0 using the subnet mask 255.255.255.240

R2(config)#interface serial 0/0/0
R2(config-if)#ip address 192.0.2.190 255.255.255.240

Requirement 6:
To enable interfaces
Use no shutdown command to enable interfaces

R2(config-if)#no shutdown
R2(config-if)#exit

Requirement 7:
Router protocol is RIPv2

Step 8:

Need to enable RIPv2 on router and advertise its directly connected networks

R2(config)#router rip

To enable RIP v2 routing protocol on router use the command version 2

R2(config-router)#version 2

Optional: no auto-summary (Since LAB networks do not have discontinuous networks)
RIP v2 is classless, and advertises routes including subnet masks, but it summarizes routes by default.
So the first things we need to do when configuring RIP v2 is turn off auto-summarization with the router command no auto-summary if you must perform routing between disconnected subnets.
R2 (config-router) # no auto-summary
Advertise the serial 0/0/0 and fast Ethernet 0/0 networks into RIP v2 using network command

R2(config-router)#network 192.0.2.176
R2(config-router)#network 209.165.201.0
R2(config-router)#end
Step 9:

Important please do not forget to save your running-config to startup-config

R2# copy running-config startup-config
