In this post, I am going to explain how the location-identity mapping database populates using Flood and Learn method. Consider the image below where VTEP01 takes the original ARP L2 frame from the HOST01 and then adds VXLAN header which includes L2VNI 20100 (think of it as an overlay L2 interface between VTEPs). VTEP01 will forward […]
Underlay Transport for VXLAN In the first section of our VXLAN course we talked about overlay, underlay, and some terminologies with this technology. By now, you know what an underlay is. Within our datacenter context the underlay is our Clos network which includes the leafs and spines and their interconnections. To get rid of STP, […]
VXLAN Improvement to Datacenter Fabric In this section, I am going to talk about data center fabric journey and how Virtual eXtensible LAN emerged. I will start with STP, then vPC and PortChannel. I won’t talk about FabricPath. We will finally jump in to VXLAN in Clos networks. STP Drawbacks Let’s architect our Clos topologies […]
Lab Introduction It is undeniable that during a learning process it would be helpful if we could deal with the examples of real-life challenges in order to commit to memory and put them into practice. For practicing in the realm of data transmission network. They help to simulate and emulate the traffic flow, configurations, related […]
we've come from the previous page here… Installing Client tools | Linux Client integration pack According to the GitHub source it says that the repo contains the equivalent of EVE-NG windows Client-side pack for Ubuntu/Debian and other Linux distros.Currently supports the following URL schemes: telnet:// capture:// docker:// vnc:// Installing eve-ng-integration from the official PPA sudo […]
MPLS Overview Multiprotocol Label Switching (MPLS) is a protocol that uses labels to route packets instead of using IP addresses. In a traditional network, each switch performs an IP routing lookup, determines a next-hop based on its routing table, and then forwards a packet to that next-hop. With MPLS, only the first device does a […]

With shared tree, multicast distribution roots at RP. RP Configuration You can configure – for different groups – as many rendezvous points as you like. But you must note that all routers in the multicast domain agree on the RP for the group. There are different ways that RPs are defined: Static RP: You configure […]
we came from the previous page here… As you remember clearly, we configured the license for IOU before then we have to add the images, In the GNS3 Preferences menu, select IOU Devices, then click New, select the option which says ‘Run this IOU device on the GNS3 VM’ (Linux users can run IOU images […]
