Based upon the exhibit,which of the following statements about the forwarding of BUM traffic is FALSE?
Answer(s): B
PE3 does not add an ESI label to packets forwarded to PE1 because PE1 is connected to the same Ethernet segment. PE3 adds an ESI label only to packets forwarded to PEs that are not connected to the same Ethernet segment, such as PE21.Verified
Ethernet Virtual Private Networks (EVPNs)
In the exhibit,MACI moves from PEI to PE2. Which of the following actions related to this MAC address mobility is performed?
Answer(s): C
PE2 advertises a MAC/IP route for MAC1 with a sequence number higher than that received from PE1. This indicates that MAC1 has moved from PE1 to PE2 and triggers a MAC withdrawal message from PE1 to remote PEs. CE1 does not generate an update message to PE1 withdrawing its MAC, nor does PE1 generate an update message to remote PEs identifying the new location of CE11. Verified
What are EVPN inclusive multicast Ethernet tag (IMET) routes used for?
EVPN inclusive multicast Ethernet tag (IMET) routes are used to discover all PEs participating in the same VPIS service. These routes are also used to build the flooding list for BUM traffic.
Based on the exhibit below, which of the following statements is FALSE?When forwarding BUM traffic, the local PE must replicate the traffic and send it as unicast to the advertising neighbor.
Answer(s): A
When forwarding BUM traffic, the local PE does not replicate the traffic and send it as unicast to the advertising neighbor. Instead, the local PE uses an MPLS transport tunnel towards the advertising neighbor and sends the traffic with an MPLS label that indicates the service.
Based on the exhibit below, which of the following statements is TRUE?
PE1 uses this BGP update to build the flooding list of the associated service. The update contains an IMET route that indicates that neighbor 10.10.10.2 is participating in a VPLS service with a network identifier of 10.
