In this post, I’m going to show you how to configure VLAN trunking with Mikrotik RouterOS, and along the way provide a brief introduction to this software and some of the functionality it offers. To see a list of VLANs in the switch, you’d use the print command in the appropriate context. Configuring VLAN Trunking.

In this post, I’m going to show you how I combined Linux network namespaces, VLANs, Open vSwitch (OVS) , and GRE tunnels to do something interesting. This post builds on information I’ve provided in previous posts: Using VLANs with OVS and libvirt (plus the update here ). I’m happy to be proven wrong, BTW.).

It’s interesting to me how much the idea of a VLAN has invaded the consciousness of data center IT professionals. Data center folks primarily tasked with managing compute workloads are nearly as familiar with VLANs as their colleagues primarily tasked with managing network connectivity. We can use a VLAN for that.

What isn’t quite so well-documented are tasks like VLANs or LACP, and that’s where I was struggling. (OK, So, let’s say that you want to set the VLANs that are allowed across an OVS port. If you’re familiar with Cisco switches, think of this process as using the switchport trunk allowed vlans command.

Following up on my earlier post on Cumulus Linux networking concepts , I wanted to build on that information with a guide on configuring VLAN trunking. You might also need to use a VLAN trunking configuration to connect a Cumulus Linux-powered switch to another switch. The VLAN-Aware Bridge.

This is part 16 of the Learning NSX series, in which I will show you how to configure VMware NSX to route to multiple external VLANs. This configuration will allow you to have logical routers that could be uplinked to any of the external VLANs, providing additional flexibility for consumers of NSX logical networks.

If you’ve been following along at home with all of my OVS-related posts (you can browse all posts using the OVS tag ), you can probably guess what this will look like (hint: it will look a little bit like the configuration I described in my post on running host management through OVS ).

In this part, we’ll discuss: VLANs. VLAN Trunks. I’ll start with VLANs. A virtual LAN , aka a VLAN , allows you to have this ability. Defined in its simplest terms, a VLAN is a layer 2 broadcast domain. In order for traffic to pass from one VLAN to another VLAN (i.e., Link Aggregation.

If you are going to use the gateway appliance to provide L2 connectivity to multiple VLANs, you’ll want to ensure that all appropriate VLANs are trunked to the external interface of the gateway appliances. If you are deploying redundant gateway appliances, make sure all the VLANs are trunked to all appliances.

One of the easiest ways to do that is to browse articles tagged LXC , tagged OVS , and/or tagged Libvirt. If you wanted to provide a virtual network that supported multiple VLANs, you could add more portgroups with the VLAN tags as I describe in my post on using VLANs with OVS and libvirt.
