(Telnet between 2 Routers)

 Objective

Understanding the telnet operations.  In this lab Router R1 is going to be telnet to Router R2.

Diagram

Procedure

1)      Check the Connectivity between 2 routers.

2)      Set the Privilege mode password on Router R2.

3)      Set the TELNET (line VTY) password on Router R2.

4)      Verify the telnet Session from Router R1 to Router R2.

5)      Disconnect the telnet Session.

Configuration         

Step 1: Check the Connectivity between 2 routers.

R1#ping 15.0.0.2

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 15.0.0.2, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 32/32/32 ms

Step 2: Set the Privilege mode password on Router R2.

R2(config)#enable password cisco

Step 3: Set the Telnet (Line VTY)password on Router R2.

R2(config)#line vty 0 4

R2(config-line)#password cisco

R2(config-line)#login

Step 4: Verify the telnet Session from Router R1 to Router R2.

R1#telnet 15.0.0.2

Trying 15.0.0.2 ... Open

User Access Verification

Password:

R2>en

R2>enable

Password:

R2#

Step 5(A): Verify the telnet line on Router R2.

R2#show line

   Tty Typ     Tx/Rx           A Modem  Roty AccO AccI  Uses    Noise   Overruns

    6   VTY                         -     -             -          -      -         0        0        0/0

Step 5(B): Verify the telnet User on Router R2.

R2#show users

    Line     User      Host(s)                  Idle    Location

*  2 vty 0               idle                 00:00:00 15.0.0.1

Step 5(C): Verify the telnet sessions from Router R1.

R1#sh sessions

Conn Host                Address             Byte  Idle Conn Name

*  1 15.0.0.2            15.0.0.2               0        0    15.0.0.2

Step 6: Switch the telnet session from Router R2  to Router R1.

R2#

Press [ Ctrl+Shift+6 and then ‘x’ ]

R1#

Note: And then Resume connection by just Enter Key.

Step 7(A): Disconect the telnet session from Router R1 (Gracefully).

R1#disconnect

Closing connection to 15.0.0.2 [confirm]

R1#

Step 7(B): Disconect the telnet session from Router R2 (Disgracefully).

R2#Clear line 2

[Connection to 15.0.0.2 closed by foreign host]

R1#
