Chapter 17. Deploying Network Virtualization
The unavoidable price of reliability is simplicity.
Tony Hoare
In this chapter, we explore administration of the different network virtualization solutions described in earlier chapters. Specifically, we examine the configuration of overlay virtual networks. EVPN, covered in Chapter 16, is assumed to be the control protocol, and VXLAN is the encapsulation protocol. Configuration of OSPF and BGP for VRF was covered in “Support for VRFs” and “BGP and VRFs”, respectively.
The following key questions are addressed in this chapter:
-
How do I configure EVPN bridging and routing in my network?/
-
How do I configure the key routing protocols (eBGP, iBGP, and OSPF) for network virtualization?
The Configuration Scenarios
EVPN provides a few configuration choices, especially the choice of routing protocol in the underlay and the handling of multidestination frames. To this end, I cover the following three high-level configurations:
-
Single eBGP session for underlay and overlay
-
OSPF for underlay, iBGP for overlay with ingress replication
-
OSPF for underlay, iBGP for overlay with routed multicast underlay
The configurations for the underlay have been laid out in the previous chapters, so I won’t be discussing them further here, especially OSPF’s. Besides this, we also have noncontrol protocol configuration such as creating VXLAN VNIs, mapping VNIs to VLANs, and so on. As per the recommendations I provided in Chapter 16, the configurations ...
