Hi Stephane & Matthew,
It has recently come to our attention that one or more claims in patent no. 9,967,174 are essential to draft-ietf-bess-evpn-pref-df-04. We have made the IPR submission as soon as possible, however, we understand that this submission is considered late since the provisional application filing date was in 2015. We apologize for this late submission. We will take necessary steps to ensure that this doesn’t happen again. Thank you for your understanding.

Regards,
Selvakumar
