7  ROUTER CONFIGURATION EXAMPLES 
7.1  VLAN Configuration 
VLAN (Virtual Local Area Network) is a logical (virtual) local area network that represents a group of 
devices which communicate on channel level regardless of their physical location. 
Objective 1: On the basis of the factory configuration, remove gi1/0/1 port from VLAN 2. 
 
Fig. 7.1 —Network structure 
Solution: 
Remove VLAN2 from gi1/0/1 port: 
esr-1000(config)# interface gi 1/0/1 
esr-1000(config-if-gi)# switchport general allowed vlan remove 2 untagged 
esr-1000(config-if-gi)# no switchport general pvid  
Configuration changes will take effect when the configuration is applied: 
esr-1000# commit 
Configuration has been successfully committed 
esr-1000# confirm 
Configuration has been successfully confirmed 
Objective 2: Configure gi1/0/1 and gi1/0/2 ports for packet transmission and reception in VLAN 2, 
VLAN 64, VLAN 2000. 
 
Fig. 7.2 —Network structure 
Solution: 
Create VLAN 2, VLAN 64, VLAN 2000 on ESR-1000: 
esr-1000(config)# vlan 2,64,2000  
 Specify VLAN 2, VLAN 64, VLAN 2000 for gi1/0/1-2 port:
