Step 1:
Click on the console host, you will get a pop-up screen CLI of Router.
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:

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.

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.

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

209.165.201.128 :::::: 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

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

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 ::::::::::: 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

192.0.2.176 :::::::: 192.0.2.177 - 192.0.2.190 :::::: 192.0.2.191
and so on ....
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

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

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

Step 9:
Important please do not forget to save your running-config to startup-config R2# copy running-config startup-config
