CCNA Question of the Week

Your router’s IP addresses should be 10.1.1.1/16 in VLAN 1 and 10.10.1.1/16 in VLAN 10. How do you configure your router’s interface FastEthernet 0/0 with these addresses and to route between VLANs 1 and 10, where VLAN 1 is the native VLAN?

  1. interface fa0/0.1
     ip address 10.1.1.1 255.255.0.0
     encapsulation dot1q 1
    interface fa0/0.2
     ip address 10.10.1.1 255.255.0.0
     encapsulation dot1q 10
  2. interface fa0/0.1
     ip address 10.1.1.1 255.255.0.0
     encapsulation dot1q vlan 1 native
    interface fa0/0.2
     ip address 10.10.1.1 255.255.0.0
     encapsulation dot1q vlan 10
  3. interface fa0/0.1
     ip address 10.1.1.1 255.255.0.0
     encapsulation dot1q 1 native
    interface fa0/0.2
     ip address 10.10.1.1 255.255.0.0
     encapsulation dot1q 10
  4. interface fa0/0.1
     ip address 10.1.1.1 255.255.0.0
     encapsulation dot1q vlan 1  
    interface fa0/0.2
     ip address 10.10.1.1 255.255.0.0
     encapsulation dot1q vlan 10
  5. interface fa0/0.1
     ip address 10.1.1.1 255.255.0.0 dot1q 1 native
    interface fa0/0.2
     ip address 10.10.1.1 255.255.0.0 dot1q 10

 

The correct answer is 3.

The “encapsulation dot1q” interface configuration command enables 802.1q trunking and specifies the VLAN number of the subinterface. The “native” keyword is required on the native VLAN, indicating that frames should not be tagged.
