Supporting Server Redundancy with NVIDIA EVPN Multihoming

This post was originally published on the Cumulus Networks site.

EVPN multihoming (EVPN-MH) is the latest addition to the NVIDIA EVPN story. In this three-part video series, I walk you through the various design elements of EVPN-MH. 

Part 1: EVPN multihoming vs. EVPN with MLAG

EVPN-MH provides support for all-active server redundancy. In this video, I offer a feature overview and a comparison with EVPN-MLAG.

Part 2: EVPN-MH: Packet flows

In this video, I dive into the various unicast packet flows in a network with EVPN-MH. This includes new data plane constructs such as MAC-ECMP and layer-2 nexthop-groups that have been introduced for the express purpose of EVPN-MH.

Part 3: EVPN-MH: Bum traffic

PIM-SM is used for optimizing flooded traffic in network with EVPN-MH. In this video, I walk through the implementation aspects of flooded traffic, including DF election and split horizon filtering.
