Inter-VLAN Routing
| Question | Answer |
|---|---|
| Gateway | A special purpose device that performs an application layer conversion of information from 1 protocol stack to another. Also is used to refer to a router or an interface on a router that enables users in an organization to connect to the Internet. |
| Internet Control Message Protocol (ICMP) | Chiefly used by TCP/IP network operating systems to send error messages indicating, for instance, that a requested service is not available or that a host or router could not be reached. |
| Inter-VLAN routing | The process of routing data between VLANs within a switched LAN. |
| Ping | A command used to verify Layer 3 connectivity. Ping sends an ICMP echo request to the destination address. When a host receives an ICMP echo request, it responds with an ICMP echo reply to confirm that it received the request. |
| Router-on-a-stick | A term used to describe the topology of a Layer2 switch trunked to an interface on a router for the purposes of inter-VLAN routing. In this topology, the router interface is configured with one logical subinterface for each VLAN. |
| Routing Table | The table, stored in a router or other internetworking device, which keeps track of routes of network destinations and metrics associated with those routes. |
| Subinterfaces | A virtual interface associated with a single physical interface on a router. |
