Experimental Purpose: Configure a switch and configure the default gateway so that the host of different network segments can connect to the switch remotely telnet login
Second, the experimental topology diagram is as follows:
Second, the experimental steps:
1, first to the PC1 host Configuration IP address and gateway(Gateway)--not worthy of gateways may Ping different, and the gateway and the next hop address is the same, or else can not ping Pass
2. Configuring the Switch S1
Enter the S1 command line interface
switch>enable --Entering privileged mode
Switch#configure Terminal --Enter global configuration mode
switch (config) #hostname S1 --Modify switch host name S1(easy to identify)
S1 (config) #enable password 111 --Set plaintext admin password to 111
S1 (config) #enable secret 222 --Set the encryption password to 222(the plaintext will not work after the encryption password is set)
S1 (config) #line vty 0 5 --Set the number of virtual terminals (typically 5 , up to three)
S1 (config-line) #password 333 --Set the Telnet password to 333
S1 (config-line) #login --login password must be configured after login , if not, remote login password is invalid
S1 (config-line) #exit --return to the previous level (global configuration mode)
S1 (config) #interface vlan 1 --Enter VLAN 1 Port
S1 (config-if) #ip address 192.168.1.1 255.255.255.0 --Configure the vlan1 with an IP address so PC1 and S1 can ping interoperability
S1 (config-if) #no shutdown --activating VLAN 1 Port
S1 (config-if) #exit ----return to the previous level (global configuration mode)
S1 (config) #ip default-gateway 192.168.1.254 --Set the default gateway to the switch S1 to achieve cross-network segment Telnet
S1 (config-if) #end --Return to privileged mode
s1#copy running-config startup-config --Save configuration (from memory RAM to hard disk NVRAM)
3. Configure Router R1
Enter the router R1 command line interface
Continue with configuration dialog? [yes/no]: n --do you want to continue configuring the dialog box? (yes/no)
router>enable --access to privileged mode
Router#configure Terminal --go to global configuration mode
Router (config) #hostname R1 --Modify the router host name to R1
R1 (config) #interface f0/0 --Go to f0/0 Port
R1 (config-if) #ip address 192.168.2.254 255.255.255.0 --Configure IP addresses for f0/0
R1 (config-if) #no shutdown --activating f0/0 Port
R1 (config-if) #interface f0/1 --Enter F0/1 Port
R1 (config-if) #ip address 192.168.1.254 255.255.255.0 --Configure IP addresses for F0/1
R1 (config-if) #no shutdown --activating F0/1 Port
R1 (config-if) #end ----return to privileged mode
r1#copy running-config startup-config --Save configuration (from memory RAM to hard disk NVRAM)
3. Go to PC1 host command line interface
Go to the PC1 host to test whether the Ping S1
# ping 192.168.1.1
(2)tenlet remote Login
# Tenlet 192.168.1.1
Passwor 333
Successful Login
Switch default gateway (for cross-segment Telnet)
