CCNA Configuration SIM Question

Refer to the topology


TUT Company 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-TUT.

Name of the router is R2-TUT
Enable-secret password is cisco1
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 must be configured as follows:
Ethernet network – router has last assignable host address in subnet
Serial network is – router has last assignable host address in the subnet. Interfaces should be enabled.
Router protocol is RIPv2


(Note: If you are not sure how RIP works, please read my RIP tutorial: http://congressreiki.ranm.org/?all=rip-routing-protocol-tutorial. Note: You can download this sim to practice here: http://congressreiki.ranm.org/?all=download/9tut.com_CCNA_RIP_Configuration.zip)

1) Name the router:

Router#configure terminal
Router(config)#hostname R2-TUT

2) Set secret password:

R2-TUT(config)# enable secret Sec@ret

3) Set password for the console:

R2-TUT(config)#line console 0
R2-TUT(config-line)#password Sec@ret2

4) Set the Telnet password:

R2-TUT(config)#line vty 0 4
R2-TUT(config-line)#password Sec@ret3

5) Assign IP address for Ethernet interface (Fa0/0):

The Ethernet network has:

Increment:32 (/27 = or 1111 1111.1111 1111.1111 1111.1110 0000)
Network address:
Broadcast address: (because 128 + 32 – 1 = 159)

Therefore the last assignable host address in this subnet is and we will assign it to Fa0/0 interface with these commands:

R2-TUT(config)# interface fa0/0
R2-TUT(config-if)#ip address
R2-TUT(config-if)#no shutdown

6) Assign IP address for Serial interface (S0/0):

Serial network has:

Increment:16 (/28 = or 1111 1111.1111 1111.1111 1111.1111 0000)
Network address:
Broadcast address
: (because 16 + 16 – 1 = 31)

So the last assignable host address in this subnet is Finally we assign it to s0/0/0 interface:

R2-TUT(config)# interface s0/0/0
R2-TUT(config-if)#ip address
R2-TUT(config-if)#no shutdown

7) Configure RIP v2 routing protocol:

R2-TUT(config)#router rip
R2-TUT(config-router)#version 2
R2-TUT#copy running-config startup-config

Note: We should use classful networks ( & when configuring RIP. If we use detailed networks ( & the router will automatically convert them into classful networks.

    RIPv1 is classful whereas RIPv2 is classless. Since you are using v2, no auto-summary should be part of the command.

    default route is required to ping??

    Do I need to enable the RIP v2 in the old router for this simulation?

    Is this lab still in 200-125 ?

    No, it’s not. But It’s a good practice though

    why are the passwords in the configuration different than passwords in the question?
    is it because we need them in encrypted form??

    i think “no auto-summary” command is not important because R1 don’t running RIP and R2 has two network connected. So R2 understand it’s network

    I did the exact same configuration however the status of the serial interface is up/down.
    can somebody help with this.

    Hi everyone, please comment if anyone who give exam recently whether 9TUT site is enough to pass 200-125 please?

    The IP Addresses of some networks differs from this web page to the lab.
    Despite of that, everything is good.
