There is some limitation on the qfx due to the Broadcom chip. On the 10k, you don’t have all the limitations to the cheap chip ^^
On the 5100 you have a lot of limitation on the 5110, you have less, but not sure it support the double tag encapsulated frames (Broadcom) I have a bunch of evpn infrastructure deployed, but I never tried to use q-in-q, so not sure if 5k will support this. I have 10k’s in the lab I may be able to test it Raphael Envoyé de mon iPhone > Le 10 sept. 2018 à 20:48, Brian Rak <b...@gameservers.com> a écrit : > > Are you trying to push multiple .1q tags onto the VXLAN traffic?
