A physical router device with an interface that routes between two or more VLANs that are attached to a VLAN network segment by a trunk link. In other words a " router on a [ TRUNK ] " which is originating from switches with independent non routing VLANs.

How many physical interfaces are required to perform inter-VLAN routing with traditional inter-VLAN routing?
Traditional inter-VLAN routing using physical interfaces does have a limitation. As the number of VLANs increases on the network, the physical approach of having one-router-interface-per-VLAN quickly becomes hindered by the physical hardware limitations of a router.Lewis, Wayne (2008-04-28). LAN Switching and Wireless, CCNA Exploration Companion Guide (Kindle Locations 6966-6968). Pearson Education (USA). Kindle Edition.
Advantages and disadvantages of inter-vlan routing?
Advantages are that it is simple to implement, A Layer-3 switch (expensive) is not required, The router provides communication between VLANs.
What does VLAN stand for?
A VLAN is a virtual LAN. In technical terms, a VLAN is a broadcast domain created by switches. Normally, it is a router creating that broadcast domain. With VLANs, a switch can create the broadcast domain. This works by, you, the administrator, putting some switch ports in a VLAN other than 1, the default VLAN. All ports in a single VLAN are in a single broadcast domain. Because switches can talk to each other, some ports on switch A can be in VLAN 10 and other ports on switch B can be in VLAN 10. Broadcasts between these devices will not be seen on any other port in any other VLAN, other than 10. However, these devices can all communicate because they are on the same VLAN. Without additional configuration, they would not be able to communicate with any other devices, not in their VLAN.
How are data frames identified and sent to the correct VLAN when exiting an Ethernet trunk?
Based on the VLAN tag.
What is the purpose of the switch command switch port access vlan 99?
the switchport access vlan 99 command is used to designate a specific VLAN for a switch port, allowing you to control how traffic on that port is treated and segregated from traffic on other ports and VLANs in the network. This is a fundamental configuration step in building and managing VLANs within a network infrastructure.
What are three features of router-on-a-stick inter-VLAN routing?

#1, #3, #5
What are the three valid VLAN routing methods?

A network administrator implements inter-VLAN routing by configuring subinterfaces on a router What is one important fact that must considered?
The IP address of each router subinterface mist be used as the default gateway for hosts on the corresponding VLAN.

When inter VLAN routing is used how are the switch ports that link to the router configured?

What is diff between layer 3 switch and router?
both are the common inter networking devices(functionally) but the layer 3 switch has the functionality of both switch and router, layer 3 switch are most commonly used in frame relay networks, layer 3 switches are also capable of inter vlan routing
How can you do inter vlan communication in a L3 D-link switch model is DGS 3612g?
inter_vlan routing on d'link DGS3612 is automatic,you just creates vlan and tag them to the port access and trunk
Why would packets from the router or hosts fail when trying to reach the switch management interfaces if the native VLAN were left in default?
The native VLAN is untagged. If the VLAN 99 traffic to the router is untagged (as it would be, because that is native on the switches), the router cannot interpret the data because there is no VLAN information in the header as expected. In turn, the router tags all VLAN 99 traffic outbound, and leaves VLAN 1 data untagged, so the switches are unable to correctly interpret either. VLAN traffic to the other VLANs should not be affected by the assignment of the native VLAN.
What is the difference between vlan and inter-vlan?
VLAN is a group of hosts with a common set of requirements that communicate as if they were attached to the same broadcast domain, regardless of their physical location. Inter VLAN is defined as two VLANS connected to each other and communicating.
