Name:
1. What is Inter-VLAN Routing?
2. Briefly explain “traditional” Inter-VLAN Routing:
3. What is a "Router-on-a-stick" and how does this differ from “traditional” InterVLAN Routing?
4. What is a third option for Inter-VLAN Routing besides the "Router-on-a-stick" or
“traditional” Inter-VLAN Routing?
5. What is the main limitation of traditional inter-VLAN routing?
6. What is used to overcome this limitation?
7. _______________ are software-based virtual interfaces that are assigned to
physical interfaces. Each ______________is configured with its own IP address,
subnet mask, and unique VLAN assignment, allowing a single physical interface
to simultaneously be part of multiple logical networks.

8. When configuring inter-VLAN routing using the router-on-a-stick model, the
physical interface of the router must be connected to a ___________________
on the adjacent switch.
9. Functionally, the router-on-a-stick model for inter-VLAN routing is the same as
using the traditional routing model, but instead of using the _________________
interfaces to perform the routing, __________________ of a single interface are
used.
10. The syntax for configuring a subinterface is always the physical interface,
followed by a _____________and a _______________________________.
11. Explain how to configure a subinterface to operate on a specific VLAN:
12. Explain the use of the “no shutdown” command with subinterfaces as opposed to
physical interfaces:
13. How is bandwidth affected by the use of subinterfaces and how can this problem
be addressed?
14. Connecting physical interfaces for inter-VLAN routing requires that the switch
ports be configured as ____________ ports, but subinterfaces require the switch
port to be configured as a ____________ port so that it can accept
____________________ traffic on the trunk link.
15. What is the financial effect of using subinterfaces over separate physical
interfaces?

16. Explain the physical and software configuration ramifications of using
subinterfaces vs. physical interfaces for inter-VLAN Routing:
17. Briefly explain the steps, modes, and commands used to create and enable the
use of subinterfaces on a single router physical interface:
18. _________________________ are the key to implementing inter-VLAN routing.
VLANs correspond to _____________________ on the network. For inter-VLAN
routing to operate, a router needs to be connected to all VLANs, either by
_______________________ interfaces or ______________________________.
Each interface, or subinterface, needs to be assigned an IP address that
corresponds to the _______________________ for which it is connected.
