I think we may be talking about different things. The situation I am testing has the pair of QFX switches. An end server has a pair of interfaces in a bond with each interface going to one QFX. VyOS is configured with an interface to each QFX but not in a bond (just two different VLANs). The designated forwarder election for the segment to the end server is handled by the QFXs.

@shthead: Yes but when it comes to multihoming there are some additional settings that should exist aswell:

@Apachez this request stems from this issue: https://forum.vyos.io/t/evpn-vxlan-esi-lag-duplicate-packets/12581

Additional information, it also appears to be broken in 1.2.5 (self built image) - seems to be the same problem.

If this is set as defaults there must be a way to enable IPv4 unicast for selected peers?
