In this guide, we are going to look at the setup of a cisco network using 802.1x wired authentication. This lab consists of the following: lab-dc01 – Windows Server 2019 AD-DS Server with AD-CS Roles lab-frad01 – Ubuntu 22.04 server for running FreeRadius dot1x-rtr – Cisco C1111-4P Router to connect Read more…
Here is a YouTube playlist I created showing the process of setting up the same Multi-Site Fabric as the guide I created on here: These videos go through all the parts I explained on here but in more detail and with practical examples.

In the last part, we got route leaking in tenant VRFs working, in this part, we will look at giving the VRFs a way out of the Fabric! We have added some new devices to the topology: We can see the EXT routers have moved to be connected to the Read more…
In the last part, we got a multiple tenant VRFs working, in this part, we will look at joining the tenants up via route leaking. Lets remind ourselves of the topology: So, currently we have our two VRFs with separate routing tables for vlan 1000 and vlan 1001: DC1-LEAF1# show Read more…
In the last part, we got a single tenant VRF working, in this part, we will look at splitting vlan 1001 off into its own separate Tenant to show a multi-tenant setup. Lets remind ourselves of the topology: All of the configuration below is for the Leaves in the topology. Read more…
In this part we are going to look at the L3VNI config to get the hosts in the two vlans talking to each other. Lets remind ourselves of the topology: All of the configuration below is for the Leaves in the topology. There is some setup on the Core switches Read more…
In this part we are going to look at the anycast gateway setup of the topology. This will help get the servers off their local network. Lets remind ourselves of the topology: Anycast gateways will be configured on each of the leaves using a virtual mac address so that mobility Read more…
In this part we are going to look at the L2VNI setup of the topology. This is basically the VLAN setup of the topology where we can define the vlans in use. Lets remind ourselves of the topology: The L2VNI setup is isolated to the leaves as the spines are Read more…
In this part we are going to look at the EVPN overlay setup of the topology. This allows the sharing of the layer 2 information learnt at each leaf switch. For this, we will use BGP. Lets remind ourselves of the topology: The BGP setup will have the spines as Read more…
