Topology Based Lab

LAB QUESTION:

This topology contains 3 routers and 1 switch. Complete the topology.
Drag the appropriate device icons to the labeled Device
Drag the appropriate connections to the locations labeled Connections.
Drag the appropriate IP addresses to the locations labeled IP address (Hint: use the given host addresses and Main router information)
To remove a device or connection, drag it away from the topology.
Use information gathered from the Main router to complete the configuration of any additional routers. No passwords are required to access the Main router . The config terminal command has been disabled for the HQ router. The router does not require any configuration.

Configure each additional router with the following
Configure the interfaces with the correct IP address and enable the interfaces.
Set the password to allow console access to consolepw
Set the password to allow telnet access to telnetpw
Set the password to allow privilege mode access to privpw

Note: Because routes are not being added to the configurations, you will not be able to ping through the internetwork.
All devices have cable autosensing capabilities disabled.
All hosts are PC’s



ANSWER:


The question tells us that they are 3 routers and 1 Switch.

Drag the appropriate device icons to the labeled Device

Device Router (1) and Router (2) are connected to main router directly.
We can confirm this because the other Device labeled has Fa 0/2 and Fa 0/4 interfaces therefore this device is a switch.

Drag the appropriate connections to the locations labeled Connections.

1. The Main router is connected over serial link to Router (2) because on Router (2) the exhibit provide S 0/0 IP address icon towards Main router.

2. Router (1) is connected to Main router using a crossover cable. We require a crossover cable to connect two similar devices.

3. To connect host A directly to Router (1) fast ethernet 0/1 we need a crossover cable

4. Straight-through cable is used to connect a router (2) and switch together.


Drag the appropriate IP addresses to the locations labeled IP address (Hint: use the given host addresses and Main router information)

Host A IP address given 192.168.152.129 /28.
Host C IP address given 192.168.152.225 /28

/28 = 11111111. 11111111.11111111.11110000
= 255.255.255.240
Subnet mask is 255.255.255.240

Various subnet networks and its valid IP address ranges for the above subnet mask

1 – 15
16 – 31
32 – 47
48 – 63
64 – 79
80 – 95
96 – 111
112 -127
128 – 143 (Host A IP address is part of this subnet network IP address range, So Router (1)
Fa 0/1 address is 192.168.152.142)
144 – 159
160 – 175
176 – 191
192 – 207
208 – 223
224 – 239 (Host C IP address is part of this subnet network IP address range, Router (2)
Fa 0/0 address is 192.168.1.238)
240 – 255


Use the console of Main router and issue show running-config command at enable mode to verify the existing IP address configured on Main router Serial interface so has to identify the Network used in connecting Router (2) over serial link and depending on the network choose the appropriate IP address for S0/0 Router(2).

Similarly verify the Fast Ethernet interface IP address configuration on main router and select a IP address for Router (1) fa 0/0 it should be from same network address range.


Configure Router (1) and Router (2) with the following configuration:

Configure the interfaces with the correct IP address and enable the interfaces.
Router (1): Configuration

Router1>enable
Router1#configure terminal

Router1(config)#interface fa 0/0
Assigns IP address to Fa 0/0 and correct subnet mask
Router1(config-if)#ip address 192.168.152.190 255.255.255.240
Enables the interface
Router1(config-if)#no shutdown

Router1(config-if)#interface fa 0/1
Assigns IP address to Fa 0/1 and correct subnet mask
Router1(config-if)#ip address 192.168.152.142 255.255.255.240
Enables the interface
Router1(config-if)#no shutdown


Set the console, telnet and privilege mode access password as follows
Console: consolepw ; Telnet: telnetpw ; Privilege mode: privpw

To set console password

Router1(config)#line console 0
Router1(config-line)#password consolepw
Router1(config-line)#login
Router1(config-line)#exit

To set telnet password
Router1(config)#line vty 0 4
Router1(config-line)#password telnetpw
Router1(config-line)#login
Router1(config-line)#exit

To set privilege mode password

Router1(config)#enable password privpw


Router (2): Configuration

Router2>enable
Router2#configure terminal

Router2(config)#interface fa 0/0
Assigns IP address to Fa 0/0 and correct subnet mask
Router2(config-if)#ip address 192.168.152.238 255.255.255.240
Enables the interface
Router2(config-if)#no shutdown

Router2(config-if)#interface serial 0/0
Assigns IP address to serial 0/0 and correct subnet mask
Router2(config-if)#ip address 192.168.152.174 255.255.255.240
Enables the interface
Router2(config-if)#no shutdown


Set the console, telnet and privilege mode access password as follows
Console: consolepw ; Telnet: telnetpw ; Privilege mode: privpw


Similar configuration needs to be done for Router (2) to set the passwords for console, telnet and privilege mode as we did for Router(1).
