Experiment 1: basic router configuration (1)-IP settings, user name modification, remote login.

Tools: IOU integrated simulator, secure CRT terminal

One: IP setting

Start the virtual machine-- > Open the IOU integrated simulator-- > enter the username and password-- >

The next steps are as follows:

Root@IOL:~# ls / / display

CiscoIOU MPLS_Option QYT_CCNA2.0 RS_MPLS_Test1 TEST

Mcast_Troubleshooting Multicasting QYT-CCNP-Test RS_Test2_BGP V5-CCNP

MPLS_eigrp Q2 QYT-RS SP_TE V5-Switch

MPLS_intergate Q2_Update RS360 SP_Y1_TS1

Root@IOL:~# cd QYT_CCNA2.0/ cd command to open QYT_CCNA2.0

Root@IOL:~/QYT_CCNA2.0#. / start.sh /. / start.sh launcher

The telnet port is taken by other process / / indicates that the program is occupied by other processes

: Address already in use

^ Croot@IOL:~/QYT_CCNA2.0# cd.. / / cd.. Command exit

Root@IOL:~# cd MPLS_intergate/

Root@IOL:~/MPLS_intergate#. / stop.sh / / enter MPLS_intergate and close

The simulator is partially completed, then open the CRT terminal

Connect the host 192.168.1.114 and quickly connect to the 2001 and 2002 routers.

As shown in the figure, note the use of telnet protocol, port 2001, hostname 192.168.1.114 2002 router configuration is similar

Note: in this example, 2001 router hostname is Branch,2002 router hostname is HQ

HQ > enable / / enter privileged mode

HQ#conf t / / enters configuration mode to control the network

Enter configuration commands, one per line. End with CNTL/Z.

HQ (config) # in

HQ (config) # interface e0ram 1 / / configure this interface

HQ (config-if) # no shu

HQ (config-if) # no shutdown / / enable this API

HQ (config-if) # ip address 192.168.1.2 255.255.255.0 / / configure the ip address

HQ (config-if) #

* Sep 12 03 Sep 45 Configured from console by console 53.735:% SYS-5-CONFIG_I:

HQ#ping 192.168.1.1 / / ping command to test whether it is connected to 2001

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:

! / /! It makes sense.

Success rate is 100 percent (5amp 5), round-trip min/avg/max = 1-1-1 ms

HQ#

Two: change the name

HQ (config) # hostname ZH / / HQ renamed to ZH

Three: remote management

The 2002 route is configured as follows:

HQ (config) # line? / / display line information

First Line number / / 6 interfaces

Aux Auxiliary line / / physical interface

Console Primary terminal line / / physical interface

Vty Virtual terminal / / virtual interface

HQ (config) # line 0 4 / / configure virtual lines

HQ (config-line) # password qyt / / set password

HQ (config-line) # transport input all / / allow any protocol to access the device

^

% Invalid input detected at'^ 'marker. / / report an error

HQ#show run | sec vty / / View the running virtual line information

Line vty 0 2

Password qyt

Login

Transport input none

Line vty 3 4

Login

Transport input none / / indicates that the configuration of the line password is not saved

HQ (config) # line 0? / / View a total of several lines

Last Line number

Branch > enable

Password: / / password is CISCO

Branch#telnet 192.168.1.2 / / telnet Test

Trying 192.168.1.2... Open / / Communication

User Access Verification

Password: / / enter the line interface password: qyt

HQ > enable / / successfully entered the HQ (2002) router and entered enable mode

Password: / / enter enable password: cisco

HQ#conf t / / enters the configuration mode of HQ

Enter configuration commands, one per line. End with CNTL/Z.

HQ (config) # end / / exit configuration mode

Note: wr saves the configuration after the configuration is completed
