Lab Purpose

R0 as a single-arm routing so that the vlan11-13 PC can access each other,

And serves the VLAN11-13 as a DHCP server

SW0

Omit Common commands

SW0 (vlan) # vtp server (unique to Cisco, resume management domain, facilitating vlan Modification Management between domains)

Device mode already vtp server.

SW0 (vlan) # vtp domain softbar.com

Changing VTP domain name from NULL to softbar.com

SW0 (vlan) # vlan 11

VLAN 11 added:

Name: VLAN0011

SW0 (vlan) # vlan 12

VLAN 12 added:

Name: VLAN0012

SW0 (vlan) # vlan 13

VLAN 13 added:

Name: VLAN0013

SW0 (vlan) # exit

After VTP is added, the vlan11-13 is automatically generated without manual Creation

SW1 (config) # int f0/11

SW1 (config-if) # sw ac vla 11

SW1 (config-if) # sw mo ac

SW1 (config-if) # int f0/12

SW1 (config-if) # sw mo ac

SW1 (config-if) # int f0/24

SW1 (config-if) # sw mo tr

 

 

 

 

 

 

PC0 ~ PC2 can automatically obtain IP addresses, gateways, and dns through DHCP.

 

PC0 (vlan11, 192.168.11.2) can ping PC2 (vlan13, 192.168.13.8)
