RFC7432 defines the MAC/IP advertisement NLRI (route type 2) for exchanging EVPN overlay end-hosts MAC addresses reachability information.  When an EVPN MAC/IP route contains more than one path to the same L2 destination, the EVPN MAC/IP best-path selection algorithm determines which of these paths should be considered as the best path to that L2 destination. 

EVPN route advertisements carry RD and RT. RD (Route Distinguisher) : prepend to the tenant’s IP Prefix or MAC address to make it globally unique. RT (Route Target) : a BGP extended community used to tag the EVPN route.  The EVPN import policy is chosen to select what is the target tenant VRF is imported from the global EVPN table.

EVPN Multihoming defines a mechanism for Multihoming PEs to quickly signal, to remote PEs, a failure in an Ethernet Segment (ES) connectivity with the use of Ethernet A-D per ES route
