Configuring Router-on-a-Stick Inter-VLAN Routing

 When it comes to routing traffic between virtual local area networks (VLANs), router-on-a-stick (ROAS) is a popular solution. With this setup, a single router is connected to a switch using an 802.1Q trunk link. The router can then be used to route traffic between VLANs.

In this blog post, we’ll discuss the basics of ROAS and how to configure inter-VLAN routing using a router-on-a-stick setup. What is Router-on-a-Stick? Router-on-a-stick is a term used to describe a router connected to a switch using an 802.1Q trunk link. This type of setup allows the router to route traffic between multiple virtual local area networks (VLANs). The trunk link between the router and the switch carries all the VLAN traffic. The router then has access to all the VLANs on the switch. This allows the router to route traffic between different VLANs. Configuring Inter-VLAN Routing with Router-on-a-Stick To configure inter-VLAN routing using router-on-a-stick, you’ll need to complete the following steps. 1. Configure the 802.1Q Trunk Link First, you’ll need to configure the 802.1Q trunk link between the router and the switch. This can be done using the appropriate commands on both the router and the switch. 2. Configure the VLANs Next, you’ll need to configure the VLANs on the switch. This can be done using the appropriate commands on the switch. 3. Configure the Interfaces Once the VLANs have been configured on the switch, you’ll need to configure the appropriate interfaces on the router. This can be done using the appropriate commands on the router. 4. Configure the IP Addresses Finally, you’ll need to configure the appropriate IP addresses on the interfaces. This can be done using the appropriate commands on the router. Once the above steps have been completed, you should be able to successfully configure inter-VLAN routing using a router-on-a-stick setup. Conclusion Router-on-a-stick is a popular solution for routing traffic between VLANs. With this setup, a single router is connected to a switch using an 802.1Q trunk link. This allows the router to route traffic between different VLANs. In this blog post, we discussed the basics of router-on-a-stick and how to configure inter-VLAN routing using a router-on-a-stick setup. We also discussed the steps required to configure the setup. With the knowledge gained from this post, you should be able to successfully configure a router-on-a-stick setup for inter-VLAN routing.
