SPINE-LEAF VXLAN is a “full mesh” network – thus, it is hard to track interface IP addresses if they are configured individually with unique IP address it will be too many IPs and too many IP Subnets!! IP address “unnumbered” is a nice way to avoid too many IPs and Subnets. Step 2: Setup OSPF routing and Ethernet interfaces IP address Ip router ospf VXLAN-UNDERLAY area 1.1.1.1 Ip router ospf VXLAN-UNDERLAY area 0.0.0.0 Note: you need to configure OSPF routing first.ĭescription “Underlay – Interfaces and Router ID” Also, we will be using this loopback IP address for SPINE-LEAF connections as “ip unnumbered” source IP address. We need “loopback 0” IP address for router ID both for OSPF and BGP. Step 1: Setup Loopback IPs on all the SPINE and LEAF switches “route-distinguisher (RD)” ID number for this POD-1 is 100 RD ID for POD-2 will be 200.īefore we move to the “step by step” configuration – enable the following features on the Cisco Nexus switches.įeatures to be enabled on the SPINE switches – ! nv overlay evpnįeatures to be enabled on the LEAF switches – !.Example – VLAN ID 10 mapped to VNI 10010, VLAN ID 20 mapped to 10020. VNI ID for this POD-1 is 1xxxx VNI ID for POD-2 will be 2xxxx.However, “SPINE to SPINE” are optional on a single-pod which can be leverage later on a multi-pod or multi-site EVPN design. NO “LEAF to LEAF” or “SPINE to SPINE” required. Physical layer connectivity are – “SPINE to LEAF” only.Both SPINE switches are “route reflector” to the LEAF switches.iBGP peering between “SPINE to LEAF” – mesh iBGP peering topology.2 x VXLAN NVE VTEP interfaces on LEAF switches (source IP 172.16.0.5 and 172.16.0.6).IP address “unnumbered” configured on the interfaces connected between SPINE and LEAF.元 VNI is Type-5 route within EVPN VXLAN – which is “IP prefix Route”.įollowing is the network topology design diagram I used here in this reference doco. L2 VNI is Type-2 route within EVPN VXLAN – which is “MAC with IP advertisement route”. This doco describes L2 VNI only – there will be another one doco covering 元VNI. As I said earlier – if you have ever configured MP-BGP address families, this will be super easy for you.

Example configuration in here are based on Cisco Nexus 9K.Ĭonfigurations are very straight forward and simple.
