## AI overview

This article explains how MLAG handles LAG member failures in VXLAN fabrics, including behavior with EVPN. Traffic can fail over over the MLAG peer link without interrupting unicast forwarding, while EVPN convergence may require updated advertisements for an optimized path. The article notes that EVPN-only multihoming presents a less favorable situation.

## Source excerpt

In the Dealing with LAG Member Failures blog post, we figured out how easy it is to deal with a LAG member failure in a traditional MLAG cluster. The failover could happen in hardware, and even if it's software-driven, it does not depend on the control plane. Let's add a bit of complexity and replace a traditional layer-2 fabric with a VXLAN fabric. The MLAG cluster members still use an MLAG peer link and an anycast VTEP IP address (more details).
