Topology

  

PC-1 is directly connected to switch with ip address 192.168.1.1 PC-2 is directly connected to switch with ip address 192.168.1.2 Switch being the intermediate device provide the communication path to both PC’s. Note: Both the PC’s must be on the same network.

 

RJ-45 to DB-9 adapter is used on the PC (COM port) to the device console Port through a roll-over cable. Hyper Terminal is used to access the Command Line Interface (CLI) of the Device. (Start --Menu—Programs—Accessories—Communications--Hyper Terminal)

Switch Console Modes of CLI:   

How to Set Telnet password: CISCO(config)#line vty 0 15 CISCO(config-line)#password cisco CISCO(config-line)#login CISCO(config-line)#exit

How to Enable The Device to Establish Telnet/SSH Session: CISCO(config)#interface vlan 1 CISCO(config-if)#ip address 10.0.0.10 255.0.0.0 CISCO(config-if)#no shutdown Note: VLAN 1 IP address is used to establish the telnet session. Go to command prompt and use telnet command to make a telnet session with the device. C:\>telnet 10.0.0.10

Configuring SSH: CISCO(config)#username taha password abc123 CISCO(config)#ip domain-name cttc.net CISCO(config)#crypto key generate rsa The name for the keys will be: CISCO.cttc.net Choose the size of the key modulus in the range of 360 to 2048 for your General Purpose Keys.

VLAN ID (System Extension ID) is added to the default priority. VLAN 1 is the default VLAN so the priority for VLAN 1 is 32769 (32768+1). Copyright@ CTTC

Enabling RSTP: Switch-1(config)#spanning-tree mode rapid-pvst Note: The above command will be issued on all the switches of the network.

Enabling Portfast feature on all switches: Switch-1(config)#spanning-tree portfast default Note: Above command will be issued to all the switches in the network. By enabling portfast feature on all the switches, will disable the STP process on all non-trunk ports. It will cause to take less time to change the state to up on all non-trunking ports. To verify this feature, connect a PC to the switch and the port will be up within 5 seconds.

After perform routing there is no ping from Router 1 to loopback 2.2.2.2, Basically the reason is that , Router 1 have the A.S number is 10 and Router 2 have A.S no: 9, that’s why there is no ping. Now I have to change the A.S no: of R2.
