BCMSN Lab1 - Routing Between VLANs and VTP Protocol
【Lab Objectives】
1. Master the VTP configuration methods.
2. Master the routing configuration methods between VLANs and the sub-interface configurations.
【Lab Topology】
【Lab Steps】
1. Configure PC1、PC2 and PC3 to be used as simulation hosts, the configuration is as follows
PC1(config)#no ip routing
PC1(config)#
PC1(config)#ip default-network 192.168.1.1
PC1(config)#
PC1(config)#interface fastEthernet 0/0
PC1(config-if)#ip address 192.168.1.10 255.255.255.0
PC1(config-if)#no shutdown
PC1(config-if)#exit
PC1(config)#
|
PC2(config)#no ip routing
PC2(config)#
PC2(config)#ip default-network 192.168.2.1
PC2(config)#
