James, ESI multihoming (load-sharing) works just fine with VxLAN encapsulation (when supported), there’s no need for additional (proprietary) mechanisms (at least with basic synchronization).
Gyan - the devil is in the details (as always) - I’m looking at multivendor EVPN VxLAN ESI designs as we speak, I’m yet to figure out how ESI type 3 (only ESI type supported in NX-OS) is going to work with ESI types 0/1 supported in Junos and Arista. I’d assume upcoming open source implementations will support type 0 (manual) only. To second James - replacing MLAG with ESI multihoming could be a really big deal in terms of simplification and normalization of the fabric (and you could finally remove peer-links!). L2 vs L3 discussion is somewhat orthogonal to that, if your services require stretched L2, whether your VTEPs are on a server or switch - you’d still be doing L2overL3. I still wouldn’t dare to deploy multivendor leafs though, but one step at a time ;-) Cheers, Jeff On Mar 4, 2020, 10:17 AM -0500, UTTARO, JAMES <ju1...@att.com>, wrote: > Gyan, > > One of the big advantages of EVPN is the MLAG capability > without the need for proprietary MLAG solutions.
