AThe service distinguisher (label or VNI) is advertised with the MAC/IP EVPN update.

BRoute targets are used to uniquely identify routes between EVIS in the case of MAC address overlaps.

CA PE uses a single MP-BGP session with a remote peer to exchange the routes for all EVIs.

DA PE advertises locally-learned MAC addresses to remote PES using EVPN type-2 routes.

Show Suggested Answer

Suggested Answer: D

PE1 does not advertise a MAC route for MAC-01 when its VPLS 20's SAP becomes operationally UP.PE1 advertises an EVPN MAC/IP route for MAC-01, which includes the IP address of Host 1 and the ESI of the Ethernet segment1.

I'm pretty sure all the options are true, except for the one about remote PES - it's supposed to be remote PEs, not PES.

Option D is the correct answer. PEs use EVPN type-2 routes to advertise locally-learned MAC addresses.
