LACP required in a EVPN/VXLAN solution when connecting an ae interface to ESXI with NIC teaming?

‎12-17-2019 08:17 AM

Hi Experts,

Preparing to migrate from juniper qfx5100-VC solution to an qfx5100 EVPN/VXLAN.

In the leagacy setup the ae interface has no LACP configured when connected to an ESXI vswitch (with NIC teaming).

Is it  a requirment to have LACP configured on the ae interface when changing to an EVPN/VXLAN solution?

Even if it's not a requirment I can see alot of disadvantages not to have it.

 

As I understand it, you must also switch to distributed switch in ESXI if LACP should be used.


Which configuration solution for QFX is best practiced when the other end is an ESXI server with NIC teaming?

I think it is better to configure lacp,

 - lacp use keepalive to check link is ok, and will not forward any packets when link is up but lacp is down

 - lacp will prevent you from creating l2 loop or packet drop , in case of miscabling and connecting one of cable to wrong port.

Hi,
I agree that LACP is prefered.
But is it mandatory in an EVPN setup?

Hi Niklas

 

No there is no specific requirement of LACP in the EVPN/VXLAN enviornment. 

 

Thanks
