In this part we are going to look at the multisite setup on the Core DC switches. The last part was a bit long so wanted to put this in its own part. Lets remind ourselves of the topology: The multisite setup is only required on the DC Core switches Read more…
In this series of guides, we will be expanding on the previous guides by making a multi-site VXLAN EVPN topology. In this part, we will look at the topology and setup the underlay network using OSPF. Here is the topology we will be working with: The switches are all Nexus Read more…
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…
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. Vlan Configuration Firstly, we need to configure a 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…
In this series of guides, we will be completing the setup of a VXLAN fabric. In this part, we will look at the topology and setup the underlay network using OSPF. Here is the topology we will be working with: The switches are all Nexus C9300v running NX-OS version 9.3(8). Read more…
