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

It is advertised with the auto-discovery per EVPN instance (A-D per EVI) route.

It is applicable to EVPN VPLS services.

It specifies the service maximum transmission unit (MTU).

It specifies a P flag that indicates whether the advertising PE is a primary PE.

Ethernet segment (ES) routes indicate the redundancy mode of the Ethernet segment.

ES routes provide the ESI label required to support the split-horizon mechanism.

Auto-discovery (A-D) routes are imported by all PES participating in the EVPN service.

A-D per Ethernet segment routes indicate the desired designated forwarder election algorithm.

VPLS 10 must be configured with two BGP instances on PE3 and PE4.

On PE3 and PE4, VPLS 10 must be configured with two different route-distinguisher values: one for VXLAN and another for MPLS.

On PE3 and PE4, VPLS 10 must be configured with two different route-target values: one for VXLAN and another for MPLS.

A BGP export policy is required on PE3 and PE4 to ensure that IMET routes originated with VXLAN encapsulation are not advertised to the peer across the core network.

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 advertises an auto-discovery per EVPN instance (A-D per EVI) route to PE3 as soon as the SAP becomes operationally

PE3 advertises an IMET route to PEI as soon as VPWS 4 is administratively enabled.

PEI and PE3 exchange their service labels using A-D per EVI routes.

PE3 and PE4 exchange their service labels over an established targeted LDP session.

PEI advertises an A-D per EVI route that includes a tag ID set to 40.

PEI advertises an A-D per EVI route that includes a non-zero Layer-2 MTLJ.

PE2 advertises an A-D per EVI route that includes a P flag set to I.

All PES advertise a MAC route that includes a non-zero MPLS label.

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 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.
