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 addition of the external router and server that are 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 10 and vlan 20: leaf-1# show Read more…
In the last part, we got a single tenant VRF working, in this part, we will look at splitting vlan 20 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…
When using BGP and peering with multiple ISPs at the edge, you can use a feature within BGP that allows you to advertise networks to a neighbour dependent on the existence of a route in the BGP RIB. This is called conditional route advertisement. In this guide, we will be Read more…
When you peer with a Service Provider using BGP. They will likely ask you if you want the full BGP table, a partial table or just a default route. Most devices you have on your companies edge, will not be able to handle the full BGP table. As even just Read more…

I am going to walk through how the LSP (Label Switched Path) is found on Cisco devices running LDP and go through a practical demonstration. First, lets look at our topology: In this demonstration we are looking at the path for traffic originating from CE_CUSTA_2 to CE_CUSTA_1. Let’s look at Read more…
Now we have tested that live motion works and that now all aspects of the network have been tested, we can begin the migration from Standard vSwitches to Distributed vSwitches. This allows central management of cluster networking. We will begin by creating the new Distributed vSwitches we need. Creating Distributed Read more…
Now we have provisioned and setup the first VM on the cluster, we can test to see if vMotion is working. A high level overview of vMotion is that it allows the live migration of VM’s between physical hosts within the cluster. This happens with zero downtime. The most we Read more…
