Routers

enable allows privileged config (if the router has a password, you'd be prompted for it.)
config to enter config mode
- router rip to enter RIP
  - Set V2 with version 2
  - Add network with network <ID>
  - Exit with just exit
- exit to exit (and save!)
show ip route shows information about routing settings (seems to include RIP and/or static)

VLANs

Once in config,

To create a vlan:
- vlan <id>
- name <something>
- end
To assign a port to a vlan:
- interface <if_name>
- switchport access vlan <id>
- exit
To set a port as trunk:
- interface <if_name>
- switchport mode trunk
- To permit/add a vlan id: switchport trunk allowed vlan <add/remove> <id>
- end

Virtual Interfaces

(Once in config )

R1(config)#interface fastEthernet 0/0
R1(config-if)#no shutdown
R1(config-if)#exit

R1(config)#interface fastEthernet 0/0.10
R1(config-subif)#encapsulation dot1Q 10
R1(config-subif)#ip address 192.168.10.254 255.255.255.0
R1(config-subif)#exit

R1(config)#interface fastEthernet 0/0.20
R1(config-subif)#encapsulation dot1Q 20                 
R1(config-subif)#ip address 192.168.20.254 255.255.255.0
