Are you sure those are two different options?
They sound quiet the same. Can you please test if We wan't to learn locally connected MACs behind the physical port into our control plane, but do not wan't to also learn everything via VXLAN floods, too - thats where we use the control plane. But how do we install MAC addresses into the control plane for local targets if |
as I know That is the reason I will suggest to put those parameters inside "bridge member" and the same level of "native-vlan" and "allowed-vlan" because these two (neigh_suppress, bridge_slave learning off) require bridge_slave. In FRR's doc[1] |
In order to minimize the flooding of ARP and ND messages in the VXLAN network, EVPN includes provisions [1] that allow participating VTEPs to suppress such messages in case they know the MAC-IP binding and can reply on behalf of the remote host. In Linux, the above is implemented in the bridge driver using a per-port option called "neigh_suppress" that was added in kernel version 4.15. [1] https://www.rfc-editor.org/rfc/rfc7432#section-10
