Dear authors of the EVPN OAM requirements and Framework<https://tools.ietf.org/html/draft-salam-bess-evpn-oam-req-frmwk-00> draft,
I have looked up the draft, and it looks to me as a good starting point for work on EVPN OAM.
I would like to clarify two points with regard to the draft:

1.       In order to pass unicast EAOM frames (LBM/LBR and LTR), the local MAC-VRF must learn the MAC address of the customer MEP and advertise it to remote PEs as a MAC/IP Advertisement route. Should this be considered as a special case of learning from the control plane (in addition to ARP/NDP/DHCP/DHCPv6 that are mentioned in RFC 7432)?

2.       Tre draft seems to propose extension of LSP Ping to test/verify connectivity to the FECs advertised as NRLI of EVPN routes. I have checked the IANA Registry, and no values for these FECs have been allocated yet.  Do you plan any specific work on this?

Regards,
Sasha
