What is needed to allow communication between the VLANs?
Two separate VLANs must communicate through a layer-3 device, like a router. Devices on a VLAN communicate with each other using layer-2. Layer-3 must be used to communicate between separate layer-2 domains.
Does EIGRP work over different VLANs?
Eigrp needs multicast and/or ip connectivity. It works fine over different vlans assuming you have multicast or ip connectivity. L3 and up protocols do not directly depend on vlans.
What device to use for Inter VLAN routing?
If you are a network administrator, you know that people will want to communicate with other people outside of your network. This is where inter-VLAN routing can help you. Inter-VLAN routing uses a Layer 3 device such as a router or a Layer 3 switch .
What is difference between a VLAN and a bridge group?
Bridge groups provide a method to group two or more ports into a single broadcast domain, where as VLAN provide a method to group many ports into a single broadcast domain or establish a number of broadcast domains (or secure groups) on a single switch. Bridge groups operate at layer 2.

How do you route a VLAN?
Three options are available for routing between VLANs:
- Use a router, with one router LAN interface connected to the switch for each and every VLAN.
- Use one router interface with trunking enabled.
- Use a Layer3 switch, a device that performs both the switching and routing operations.
How do you use a VLAN?
Select Switching>VLAN>Basic > VLAN Configuration. Create a static VLAN by specifying a VLAN ID and VLAN name, and, from the VLAN Type menu, selecting Static. Click the Add button. The new VLAN is added to the configuration.
What happens to VLAN traffic when it leaves the port?
If the data matches the PVID the vlan traffic will be stripped from the data as it leaves the port. VLAN traffic entering the port will be honored and passed into the switch.
How to define the VLANs allowed on a trunk link?
Even if you specify a VLAN range, it is ignored. To modify the allowed VLANs list, use a combination of the clear trunk or set trunk commands to specify the allowed VLANs. To remove VLANs from the allowed VLANs list for a trunk, issue the clear trunk mod_num/port_num vlans command.
How is a tag assigned to a VLAN?
All inbound untagged traffic gets a tag assigned to it (the ports untagged VLAN ID) once it enters into the switch. Then switch then pushes it out of all ports that have a corresponding VLAN. If the port is set for untagged on that VLAN, it strips the tag.
What is the default VLAN for a network switch?
General Networking. The default vlan ( 1 ) is applied to all data entering the switch (unless the ports PVID has been changed) and if the port is set to access stripped from the data as it leaves the switch. If the port is setup as a VLAN trunk the vlan information (tagging) is left on the data as it leaves the switch.
