E.  

A.  

The updates include an Ethernet segment identifier label that is used in loop prevention.

B.  

The updates advertise the Ethernet segment availability in a given EVPN service.

C.  

The updates include an MPLS label that is set to a non-zero value.

A.  

EVPN allows a service provider to deliver multiple services over a single core network.

B.  

The customer data is encapsulated and then tunneled between the PE routers.

C.  

EVPN-MPLS encapsulated data has a label that uniquely identifies each service.

D.  

EVPN-MPLS provides services over a simple IP network.

A.  

PEI advertises an A-D per ES route which indicates that ESI 1 is operating in a single-active redundancy mode.

B.  

PEI advertises an A-D per EVI route which includes a P flag set to I to indicate that PEI is the DF for EVI 20.

C.  

PE3 advertises an A-D per ES route which indicates that ESI I is operating in a single-active redundancy mode.

D.  

When PEI learns MAC-01, it advertises a MAC/IP route which indicates that MAC-OI is associated with ESI I.

B.  

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

C.  

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

D.  

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

A.  

PE3 replicates the traffic and sends it to all PES in its VPLS I flooding list.

B.  

PE3 adds an ESI label to packets forwarded to PEI because PEI is connected to the same Ethernet segment.

C.  

PEI forwards the traffic received from PE3 to CEI, and CEI discards it based upon the ESI label.

D.  

PE2 decapsulates the packets received from PE3 and forwards the frames to CE2.
