Question

Design a network with the following requirements:

- 4 LANS separated by a WAN

- Utilize any Class C address; any routing protocol

-Implement the following:

In Router 0,

1. Banner

2. Time-out

3. Block Log in

4. Telnet

In Router 1:

1. Privilege Level 15 for User1

2. Privilege level 3 for User 2

3. SSH

Answer 1

Given scenario is 4 LANS separated by a WAN and using any Class C address and any routing protocol

Here choosing the network 192.168.10.0/24 and subnetting it and also choooosing the RIP version 2 protocol for routing.

Network is designed in the packet tracer

Configure routing using RIPV2

Router0

Router0(config)#router rip

Router0(config-router)#version 2

Router0(config-router)#network 192.168.10.0

Router0(config-router)#network 192.168.10.32

Router0(config-router)#network 192.168.10.128

Router1

Router1(config)#router rip

Router1(config-router)#version 2

Router1(config-router)#network 192.168.10.64

Router1(config-router)#network 192.168.10.96

Check connectivity between the LANs using PING

Ping from PC0 to PC1 ,PC2 and PC3

Implement the given requirements

Router 0

1. Banner

Router0(config)#banner motd "Restricted Device"

Router0(config)#do wr

Router0(config)#exit

Router0#logout

2. Time-out

Router0(config)#line console 0

Router0(config-line)#exec-timeout 5

3. Block Log in

Router0(config)#login block-for 60 attempts 3 within 5

For blocking login for 60 minutes when attempts 3 invalid login within 5 minutes.

4. Telnet

Set enable password and telnet password

Router0(config)#enable password cisco123

Router0(config)#line vty 0 4

Router0(config-line)#password cisco

Router0(config-line)#login

Router0(config-line)#

Check telnet access from PC0

Check telnet access from PC3

Router 1

1. Privilege Level 15 for User1

Router1(config)#username User1 privilege 15 password cisco

2. Privilege level 3 for User 2

Router1(config)#username User2 privilege 3 password cisco123

3. SSH

Router1(config)#ip domain name cisco

Router1(config)#line vty 0 4

Router1(config-line)#login local

Router1(config-line)#transport input ssh

Router1(config-line)#exit

Router1(config)#crypto key generate rsa

The name for the keys will be: Router1.cisco

Choose the size of the key modulus in the range of 360 to 2048 for your

General Purpose Keys. Choosing a key modulus greater than 512 may take

a few minutes.

How many bits in the modulus [512]: 1024

% Generating 1024 bit RSA keys, keys will be non-exportable...[OK]
