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?

In traditional inter-VLAN routing (also known as "router-on-a-stick"), only one physical interface is required on the router. However, this single physical interface needs to be configured with multiple sub interfaces, each corresponding to a different VLAN. The router uses these sub interfaces to route traffic between VLANs. The configuration involves: One physical interface on the router (e.g., GigabitEthernet0/1). Multiple sub interfaces (e.g., GigabitEthernet0/1.10, GigabitEthernet0/1.20) corresponding to different VLANs. Each sub interface is assigned an IP address in the respective VLAN's subnet. This setup enables inter-VLAN routing by allowing the router to route traffic between the VLANs using a single physical interface.


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.

When implementing a router-on-a-stick what must be configured on the router to ensure connectivity?

When implementing a router-on-a-stick configuration, you must create sub-interfaces on the router's physical interface connected to the switch, with each sub-interface assigned to a different VLAN. Each sub-interface should be configured with an IP address corresponding to its VLAN's subnet, and the encapsulation type (usually 802.1Q) must be specified for each sub-interface. Additionally, ensure that the switch ports connected to the router are set to trunk mode to allow multiple VLAN traffic to pass through the link.


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.
