PTP for NDI deployment in a NDFC VXLAN EVPN Multisite

[Luis Perez]

Hi community looking for some advices related with:

Planning a VXLAN EVPN Multisite Deployment with back to back connections between spines acting also as BGW, then we need to enable NDI and saw PTP is a requirement. So a pair of questions.

- Can i use internal leafs of the already deployued fabric as PTP GMs, i have Nexus 93180YC-FX3 acting as leafs?

- Some documentation of reference about additional hardware needed (GNSS antenna or something adittional) to enable PTP GM in that devices?

- I suppose NDFC has template for that PTP configuration, could you confirm?

Hello @Luis Perez 

If you edit your Fabric, and go to the 'Advanced' menu, you could see PTP references.

Thanks M02@rt37 your comment answer my last question related with the ptp config on the fabric, now lloking some advices on the first question because already found info about the GNSS receiver and checked that is possible to use NTP as clock source for the PTP GM.
