Static Routing and VTP implementation

Idea: configure the IP address of the interface connecting different routers to the same network segment, while the interfaces inside the router implement communication through direct connection routing. The static route added by the vro is the interface IP address and subnet mask of the vro to be connected, and the interface IP address of the directly connected vro! That is, the next hop address.

Idea: VTP is used to manage VLANs between switches. There are three modes: Server, client, and transparent, the client cannot delete or modify VLAN information and can automatically synchronize VLAN information. The transparent end is not affected. You can add or delete VLANs by yourself, and only play the role of one relay for transmission. The communication between the vswitch and the vswitch is transmitted through the trunk.

1. Set the Host Name

(CONF) # hostname SW1

2. Configure the Enable Password

(CONF) # enable password 123 --- plaintext Password

(CONF) # enable secret 456 -- encrypted password

3. Configure the password for the control line

(CONF) # Line console 0

(Config-line) # password 123

(Config-line) # Login

4. configure remote management (vty)

(1) configure a management IP address (vlan1 Interface) for the device)

SW1 (config) # interface VLAN 1

SW1 (config-If) # IP address 192.168.1.1 255.255.255.0

SW1 (config-If) # No Shutdown

SW1 (config-If) # exit

SW1 (config) # Line vty 0 4

SW1 (config-line) # password 123456

SW1 (config-line) # Login

Query configuration files

# Show running-config

Save configuration file

SW1 # copy running-config startup-config is equal to SW1 # Write

Destination filename [startup-config]?

[OK]

Verify

SW1 (config) # End

SW1 # exit

User Access Verification

Password: 123 (console password)

SW1> enable (privileged password)

Open a command prompt and configure an IP address (192.168.1.2) for the PC)

PC> Telnet 192.168.1.1

VLAN Division

1. Create a VLAN

Switch (config) # hostname SW1

SW1 (config) # VLAN 10 -- create vlan10 globally

SW1 (config-VLAN) # name upl_vlan10 -- name vlan10

SW1 # VLAN database -- enter the VLAN Database

SW1 (VLAN) # VLAN 20 -- create vlan20

VLAN 20 added:

Name: vlan0020

SW1 (VLAN) # exit

Apply completed.

Exiting ....

SW1 # conf t

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

SW1 (config) # VLAN 20

SW1 (config-VLAN) # name upl_vlan20 -- enter global Rename to vlan20

SW1 (config) # do show VLAN -- Query VLAN

2. Divide ports into VLANs for isolated Broadcast

SW1 (config) # interface F0/1

SW1 (config-If) # switchport access VLAN 10

SW1 (config) # interface F0/2

SW1 (config-If) # switchport access VLAN 10

SW1 (config) # interface range F0/3-4

SW1 (config-if-range) # switchport access VLAN 20
