This concern applies to route target VPN membership in a different scenario where operators need to control which provider-edge VRFs import a shared customer's VPN routes. For the deployed controlled Internet breakout approach, the relevant caution is instead that stateful firewall and return-path policies must match the breakout design.

This concern applies to PIM-SSM source-specific join in a different scenario where operators need to let subscribers request an explicitly selected multicast source and group pair. For the deployed controlled Internet breakout approach, the relevant caution is instead that stateful firewall and return-path policies must match the breakout design.

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 controlled Internet breakout approach, the relevant caution is instead that stateful firewall and return-path policies must match the breakout design.

VRF customer routing isolation instead addresses a different condition: prevent two subscribers with overlapping private addresses from mixing their forwarding routes. It would instead require you to create separate VRFs and bind the correct customer interfaces to each table, not the stated goal to move a customer site to a new PE while another tenant uses the same IP block.

EVPN MAC/IP route type 2 instead addresses a different condition: advertise a reachable customer MAC address over a provider EVPN fabric. It would instead require you to enable MAC learning and Type-2 EVPN route advertisement for the correct service, not the stated goal to move a customer site to a new PE while another tenant uses the same IP block.

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 move a customer site to a new PE while another tenant uses the same IP block.

The proposed step is for VRF customer routing isolation, whose purpose is to prevent two subscribers with overlapping private addresses from mixing their forwarding routes. It would not perform the necessary L3VPN overlapping subnet migration operation: retain unique VRF and RD identities during the CE handoff change.

The observation would verify VRF customer routing isolation under the separate requirement to prevent two subscribers with overlapping private addresses from mixing their forwarding routes. It does not demonstrate the needed L3VPN overlapping subnet migration result: the migrated site's VPN paths resolve without disrupting the unrelated tenant.

This defect belongs to VRF customer routing isolation, where the affected outcome is to prevent two subscribers with overlapping private addresses from mixing their forwarding routes. It is not the direct failure mode identified for the L3VPN overlapping subnet migration design in this case: the shared prefix is leaked into the global routing table during migration.

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 L3VPN overlapping subnet migration approach, the relevant caution is instead that temporary duplicate site advertisements require careful route preference.

route target VPN membership instead addresses a different condition: control which provider-edge VRFs import a shared customer's VPN routes. It would instead require you to configure matching import and export route-target policies between authorized VRFs, not the stated goal to investigate a VPNv4 route that exists in BGP but does not carry packets end to end.

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 investigate a VPNv4 route that exists in BGP but does not carry packets end to end.

PIM-SM shared tree initial join instead addresses a different condition: provide multicast to sparse receivers through an RP-assisted distribution process. It would instead require you to configure PIM sparse mode and consistent rendezvous point reachability, not the stated goal to investigate a VPNv4 route that exists in BGP but does not carry packets end to end.

The proposed step is for route target VPN membership, whose purpose is to control which provider-edge VRFs import a shared customer's VPN routes. It would not perform the necessary L3VPN label blackhole diagnosis operation: check transport label and VPN service label resolution from ingress to egress.

The observation would verify route target VPN membership under the separate requirement to control which provider-edge VRFs import a shared customer's VPN routes. It does not demonstrate the needed L3VPN label blackhole diagnosis result: the programmed FIB includes valid next hop and VPN egress label disposition.

This defect belongs to route target VPN membership, where the affected outcome is to control which provider-edge VRFs import a shared customer's VPN routes. It is not the direct failure mode identified for the L3VPN label blackhole diagnosis design in this case: BGP reachability alone is accepted as proof that labeled forwarding is correct.
