Of course folks will worry about scaling and number of BFD sessions to be run PE-PE. But if BFD between all PEs would be an option why RR to PE in the local area would not be a viable solution ? Both would be multihop, both would be subject to all transit failures etc ... Also just FYI this discussion is not about EVPN :) Some people claimed that the solution should not even consider BGP presence for any service. Thx, R.
