4A0-115 Nokia Ethernet Virtual Private Network Services Question and Answers

The local AC tag ID configured on PE2 must match the local AC tag ID configured on PEI.

The remote AC tag ID configured on PE2 must match the remote AC tag ID configured on PE3.

The local AC tag ID and the remote AC tag ID configured on PE2 must match.

The local AC tag ID configured on PEI must match the local AC tag ID configured on PE3.

When forwarding BUM traffic, the local PE must replicate the traffic and send it as unicast to the advertising neighbor.

The MPLS label 524284 presented indicates the service label value that the neighbor 10.10.10.2 uses to forward BUM traffic to PEI.

When forwarding BUM traffic, the local PE uses an MPLS transport tunnel towards the advertising neighbor.

The IMET route is imported by a local VPLS configured with a route-target value of 65100:10.

In the single-active mode, the CE requires a LAG to be configured between the CE and all attached PEs.

In the single-active mode, the CE forwards traffic to all attached PES and receives traffic from a single PE.

In the all-active mode, all PES attached to a CE can forward traffic to and from the CE.

The Nokia 7750 SR supports a CE being multi-homed to a maximum of two PEs.

PEI populates this information into the local VPLS FDB.

Neighbors 10.10.10.2 and 10.10.10.3 have proxy-ARP enabled for the VPLS.

Neighbors 10.10.10.2 and 10.10.10.3 have a service that uses a network identifier of 10.

PEI uses VXLAN tunnels to reach neighbors 10.10.10.2 and 10.10.10.3.

Allows Tx unicast, blocks Rx unicast, allows Tx BUM, blocks Rx BUM

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

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

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

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

PEI consults the FDB of RVPLS 1 and forwards the traffic to the local interface of VPRN 11.

PEI encapsulates the packet with two labels: an outer transport label and an inner service label.

PE2 inspects the service label and determines that it is associated with RVPLS 2.

PE2 consults the FDB of RVPLS 2 and forwards the traffic to Host 2.

PEI advertises an EVPN IP-Prefix route for prefix 10.10.1.0/24 to PE3. The BGP update includes MAC-OI as on overlay index.

PEI advertises an EVPN MAC route for MAC-OI to PE3. The BGP update includes the route-target value configured for VPRN 15.

PE3 advertises a VPN-IPv4 route for prefix 10.10.1.0/24 to PE4. The BGP update includes an MPLS service label.

PE4 advertises an EVPN IP-Prefix route for prefix 10.10.1.0/24 to PE2. The BGP update includes MAC-04 as an overlay index.

PEI does not flood the packet because PEI is acting as non-designated forwarder (non-DF) for VPLS 10.

PEI sends the packet to PE2 but not to PE3 because PE3 is connected to the originating ES.

PEI sends the packet to PE2 and to PE3. An ESI label is included only in the packet sent to PE2.

PEI sends the packet to PE2 and to PE3. An ESI label is included only in the packet sent to PE3.
