1 Router (Cisco 1941 with Cisco IOS Release 15.2(4)M3 universal image or comparable). Router on a stick relies on one ethernet link that is configured as IEEE. In computing, a router on a stick, also known as a one-armed router, is a router that has a. If you are unsure, contact your instructor. Router R1 is a one-armed router carrying out inter-VLAN routing. Note: Make sure that the routers and switches have been erased and have no startup configurations. Refer to the Router Interface Summary Table at the end of this lab for the correct interface identifiers. Depending on the model and Cisco IOS version, the commands available and output produced might vary from what is shown in the labs. Other routers, switches and Cisco IOS versions can be used. The switches used are Cisco Catalyst 2960s with Cisco IOS, Release 15.0(2) (lanbasek9 image). Note: The routers used with CCNA hands-on labs are Cisco 1941 Integrated Services Routers (ISRs) with Cisco IOS, Release 15.2(4)M3 (universalk9 image). Test your knowledge by trying to configure the devices without referring to the appendix. Two separate VLANs will be configured on the switches, and you will set up routing between the VLANs. In this lab, you will set up one router with two switches attached via the router Gigabit Ethernet interfaces. The required switch VLAN configuration commands are provided in Appendix A of this lab. What is an advantage of using legacy Inter VLAN routing One of the benefits of legacy inter-VLAN routing is ease of configuration. 
Note: This lab provides minimal assistance with the actual commands necessary to configure the router and switches. Use the vlan vlanid global configuration mode command to create VLANs. As shown in the figure, router R1 is connected to switch ports F0/4 and F0/5, which have been configured for VLANs 10 and 30, respectively. In this lab, you will set up one router with two switches attached via the router Gigabit Ethernet interfaces. To configure legacy inter-VLAN routing, start by configuring the switch. One of the benefits of legacy inter-VLAN routing is ease of configuration. The first block will be for VLAN 2, the second will be for VLAN 3 and the last one will be for VLAN 4. We will use 10.0.0.0/24, 20.0.0.0/24 and 30.0.0.0/24 blocks for our Packet Tracer Router on Stick topology example. Also, you may encounter per-interface inter-VLAN routing in organizations with very small networks. IP Configurations For Inter VLAN Routing. Legacy inter-VLAN routing is seldom used in today’s networks however, it is helpful to configure and understand this type of routing before moving on to router-on-a-stick (trunk-based) inter-VLAN routing or configuring Layer-3 switching. Part 3: Verify Trunking, VLANs, Routing, and Connectivity Part 2: Configure Switches with VLANs and Trunking Part 1: Build the Network and Configure Basic Device Settings The Router operates like normal when routing packets between two networks.Lab – Configuring Per-Interface Inter-VLAN Routing Make interface fa0/3 a trunk port and for security measures I made sure that only VLAN 10 and 20 are allowed. The Router doesn’t know that it has two connections to the same switch - nor does it need to. The simplest way to enable routing between the two VLANs to simply connect an additional port from each VLAN into a Router. How do I route a VLAN to a Layer 2 switch?
Determine the IP addresses you want to assign to the VLAN interface on the switch. 
Use the show vlan command in order to verify that the VLANs exist in the VLAN database. Make note of the VLANs that you want to route between. Enable routing on the switch with the ip routing command. People also ask, how do I set up inter VLAN routing? The traffic can then be routed to the appropriate VLAN. One may also ask, what is the advantage of using legacy Inter VLAN routing? Legacy Inter– VLAN Routing This then allows each router interface to accept traffic from the VLAN associated with the connected switches interface. The switch ports connected to the router are placed in access mode and each physical interface is assigned to a different VLAN. The switch ports connected to the router are placed in access mode and each physical interface is assigned to a different VLAN. Legacy Inter-VLAN Routing In this legacy approach, inter-VLAN routing is performed by connecting different physical router interfaces to different physical switch ports. Legacy Inter– VLAN Routing In this legacy approach, inter– VLAN routing is performed by connecting different physical router interfaces to different physical switch ports. Simply so, what is legacy Inter VLAN routing?
