This concern applies to EVPN route target matching in a different scenario where operators need to restrict the import of BGP EVPN routes to the correct tenant service. For the deployed EVPN IP prefix type 5 approach, the relevant caution is instead that route-target and next-hop resolution remain prerequisites.

This concern applies to L3VPN overlapping subnet migration in a different scenario where operators need to move a customer site to a new PE while another tenant uses the same IP block. For the deployed EVPN IP prefix type 5 approach, the relevant caution is instead that route-target and next-hop resolution remain prerequisites.

This concern applies to VRF customer routing isolation in a different scenario where operators need to prevent two subscribers with overlapping private addresses from mixing their forwarding routes. For the deployed EVPN IP prefix type 5 approach, the relevant caution is instead that route-target and next-hop resolution remain prerequisites.

carrier supporting carrier VPN instead addresses a different condition: let a carrier customer transport its own labeled VPN services over another carrier backbone. It would instead require you to build a supported carrier-supporting-carrier architecture with appropriate labeled route exchange, not the stated goal to restrict the import of BGP EVPN routes to the correct tenant service.

traffic policing excess handling instead addresses a different condition: enforce a hard contracted rate with an explicit action for out-of-profile traffic. It would instead require you to use a policer with appropriate committed rate and drop or remark behavior, not the stated goal to restrict the import of BGP EVPN routes to the correct tenant service.

Ethernet CFM continuity check instead addresses a different condition: detect loss of Ethernet service connectivity between provider maintenance endpoints. It would instead require you to configure supported Ethernet connectivity fault management maintenance associations, not the stated goal to restrict the import of BGP EVPN routes to the correct tenant service.

The proposed step is for carrier supporting carrier VPN, whose purpose is to let a carrier customer transport its own labeled VPN services over another carrier backbone. It would not perform the necessary EVPN route target matching operation: configure the intended import/export route target set for each EVI.

It would not perform the necessary EVPN route target matching operation: configure the intended import/export route target set for each EVI.

It would not perform the necessary EVPN route target matching operation: configure the intended import/export route target set for each EVI.

The observation would verify carrier supporting carrier VPN under the separate requirement to let a carrier customer transport its own labeled VPN services over another carrier backbone. It does not demonstrate the needed EVPN route target matching result: authorized routes appear only in the matching customer service tables.

This defect belongs to carrier supporting carrier VPN, where the affected outcome is to let a carrier customer transport its own labeled VPN services over another carrier backbone. It is not the direct failure mode identified for the EVPN route target matching design in this case: a foreign tenant EVI imports every received EVPN route without filtering.

This concern applies to carrier supporting carrier VPN in a different scenario where operators need to let a carrier customer transport its own labeled VPN services over another carrier backbone. For the deployed EVPN route target matching approach, the relevant caution is instead that incorrect route targets can leak connectivity between customer services.

inter-AS VPN option A separation instead addresses a different condition: interconnect L3VPN sites across two providers without sharing their internal VPNv4 BGP tables. It would instead require you to exchange isolated VRF routes over explicit per-VRF handoff subinterfaces, not the stated goal to maintain forwarding when a customer virtual machine moves between EVPN access PEs.

IGMPv3 inclusion filtering instead addresses a different condition: request multicast only from one specified source at the IPv4 receiver edge. It would instead require you to send appropriate IGMPv3 INCLUDE-mode membership state, not the stated goal to maintain forwarding when a customer virtual machine moves between EVPN access PEs.

DSCP class marking at ingress instead addresses a different condition: mark customer traffic into a contracted provider forwarding class before queuing. It would instead require you to classify trusted traffic and apply the agreed DSCP or MPLS Traffic Class mapping, not the stated goal to maintain forwarding when a customer virtual machine moves between EVPN access PEs.

The proposed step is for inter-AS VPN option A separation, whose purpose is to interconnect L3VPN sites across two providers without sharing their internal VPNv4 BGP tables. It would not perform the necessary EVPN MAC mobility control operation: apply MAC mobility and sequence handling for newly advertised locations.

The observation would verify inter-AS VPN option A separation under the separate requirement to interconnect L3VPN sites across two providers without sharing their internal VPNv4 BGP tables. It does not demonstrate the needed EVPN MAC mobility control result: remote sites converge on the latest legitimate MAC attachment point.

This defect belongs to inter-AS VPN option A separation, where the affected outcome is to interconnect L3VPN sites across two providers without sharing their internal VPNv4 BGP tables. It is not the direct failure mode identified for the EVPN MAC mobility control design in this case: older advertisements repeatedly overwrite the new location and cause oscillation.

This concern applies to inter-AS VPN option A separation in a different scenario where operators need to interconnect L3VPN sites across two providers without sharing their internal VPNv4 BGP tables. For the deployed EVPN MAC mobility control approach, the relevant caution is instead that rapidly flapping customer MACs can still trigger mobility dampening.
