A case study of NAT, routing aggregation and single arm routing

Experiments show that this experiment involves dynamic NAT, single arm routing, routing aggregation, RIP configuration, for VLAN communication and intranet access to extranet through NAT conversion.

Configuring Link Aggregation

Switch (config) #int Port-channel 1

Switch (config-if) #int range f0/10-11

Switch (Config-if-range) #channel-group 1 mode on

Switch (Config-if-range) #int Port-channel 1

Switch (config-if) #switchport mode trunk

Switch (config-if) #no shutdown

Switch (config-if) #exit

Switch (config) #

Configuring VLANs

Switch (config) #vlan 10

Switch (Config-vlan) #int F0/1

Switch (config-if) #switchport mode access

Switch (config-if) #switchport Access VLAN 10

Switch (config-if) #no shutdown

Switch (config-if) #vlan 20

Switch (Config-vlan) #int F0/2

Switch (config-if) #switchport mode access

Switch (config-if) #switchport Access VLAN 20

Switch (config-if) #no shutdown

Configure F0/24 Trunk

Switch (config) #int f0/24

Switch (config-if) #switchport mode trunk

Switch (config-if) #no shutdown

Switch (config-if) #exit
