Jeffrey,
I was unaware that local bias had been standardized. Will take a
read..
Thanks,

EVPN/VLXAN uses Local Bias method for MH split horizon, which is specified in
RFC 8365.
Extending EVPN to servers don’t require new IETF standards – the servers just
need to support existing relevant standards. Having said that, with many
servers in the underlay, routing in the underlay needs to be able to scale
well. For that you can run BGP in the underlay (RFC 7938), or RIFT
(draft-ietf-rift-rift), or LSVR (draft-ietf-lsvr-bgp-spf).

Gyan,
One of the big advantages of EVPN is the MLAG capability without
the need for proprietary MLAG solutions. We have been actively testing EV-LAG
to accomplish this in the WAN for L2 services.. That being said, we use
EVPN/MPLS where MH ( EV-LAG ) is conveyed via labels.. My understanding is that
when using EVPN/VXLAN proprietary mechanisms are need to make EV-LAG work.. The
is no SH label..
Thanks,

Dear BESS WG
Is anyone aware of any IETF BGP development in the Data Center arena to extend
BGP VXLAN EVPN to a blade server Hypervisor making the Hypervisor part of the
vxlan fabric. This could eliminate use of MLAG on the leaf switches and
eliminate L2 completely from the vxlan fabric thereby maximizing stability.
Kind regards,
Gyan
