Functionally the same as using the traditional routing model.Each subinterface is configured with its own IP address, subnet mask, and unique VLAN assignment.Subinterfaces are softwaresoftware-based virtual interfaces that are assigned to physical interfaces.Overcomes the hardware limitation of a router.RouterRouter-onon-a-stick InterInter-VLAN Routing:.It is very expensive to add an Ethernet Interface.Routers have a limited number of physical interfaces that they can use to connect to different VLANs.As the number of VLANs increases on a network, the physical approach of having one router interface per VLAN quickly becomes hindered by the physical hardware limitations of a router.Traditional interinter-VLAN routing using physical interfaces does have a limitation.Interfaces and Subinterfaces Traditional InterInter-VLAN Routing Inter-VLAN Interfaces and Subinterfaces Router tags Traditional InterInter-VLAN RoutingRouter Inter-VLAN the frame Responds for VLAN 30 Routing table: And switches it 172.17.10.0 – F0/0 to Port F0/1. In this configuration, network devices can use the router as a gateway to access the devices connected to the other VLANs.Each interface is also configured with an IP address for the subnet associated with the particular VLAN that it is connected to.Traditional routing requires routers to have multiple physical interfaces to facilitate interinter-VLAN routing.Uses Switch Virtual Interfaces (SVI) to retag the frame.Layer 3 Switch InterInter-VLAN Routing:.RouterRouter-onon-a-stick InterInter-VLAN Routing: Internally Routed to.RouterRouter-onon-a-stick InterInter-VLAN Routing.InterInter-VLAN routing, routing, then, is a process of forwarding traffic from one VLAN to another VLAN using a router.To allow VLANs to communicate, we need a router to communicate among separate broadcast domains and unique IP subnetworks.Computers on separate VLANs are, by default, default, not able to communicate.Each VLAN is a unique broadcast domain.If anyone finds any errors or omissions, please let me know at:.His material and additional information was used as a reference in their creation.
