This concern applies to CGNAT address sharing logging in a different scenario where operators need to serve multiple IPv4 subscribers from shared public address resources. For the deployed MAP-T stateless access translation approach, the relevant caution is instead that port-set sharing restricts subscriber port availability.

This concern applies to BGP community tagging policy in a different scenario where operators need to identify a class of routes consistently across multiple policy boundaries. For the deployed MAP-T stateless access translation approach, the relevant caution is instead that port-set sharing restricts subscriber port availability.

This concern applies to RPL inbound AS-path policy in a different scenario where operators need to reject untrusted routes with prohibited AS-path characteristics. For the deployed MAP-T stateless access translation approach, the relevant caution is instead that port-set sharing restricts subscriber port availability.

DS-Lite IPv4 transport over IPv6 instead addresses a different condition: carry a subscriber IPv4 service over an IPv6-only access network. It would instead require you to tunnel subscriber IPv4 packets to a provider AFTR for IPv4 address translation, not the stated goal to serve multiple IPv4 subscribers from shared public address resources.

OSPFv3 IPv6 routing instead addresses a different condition: exchange IPv6 prefixes using the appropriate OSPF protocol version. It would instead require you to configure OSPFv3 address-family and interface participation for IPv6, not the stated goal to serve multiple IPv4 subscribers from shared public address resources.

BGP network statement origination instead addresses a different condition: advertise a local prefix only when a matching route exists in the local table. It would instead require you to configure BGP network origination for an exact eligible route, not the stated goal to serve multiple IPv4 subscribers from shared public address resources.

The proposed step is for DS-Lite IPv4 transport over IPv6, whose purpose is to carry a subscriber IPv4 service over an IPv6-only access network. It would not perform the necessary CGNAT address sharing logging operation: deploy stateful carrier-grade NAT with accurate address-port allocation logging.

The observation would verify DS-Lite IPv4 transport over IPv6 under the separate requirement to carry a subscriber IPv4 service over an IPv6-only access network. It does not demonstrate the needed CGNAT address sharing logging result: sessions reach the Internet and logs map translated tuples back to subscribers.

This defect belongs to DS-Lite IPv4 transport over IPv6, where the affected outcome is to carry a subscriber IPv4 service over an IPv6-only access network. It is not the direct failure mode identified for the CGNAT address sharing logging design in this case: a shared source address is logged without ports or timestamps needed for attribution.

This concern applies to DS-Lite IPv4 transport over IPv6 in a different scenario where operators need to carry a subscriber IPv4 service over an IPv6-only access network. For the deployed CGNAT address sharing logging approach, the relevant caution is instead that NAT state and port exhaustion can restrict subscriber scale.

CGNAT address sharing logging instead addresses a different condition: serve multiple IPv4 subscribers from shared public address resources. It would instead require you to deploy stateful carrier-grade NAT with accurate address-port allocation logging, not the stated goal to carry a subscriber IPv4 service over an IPv6-only access network.

RPL route policy execution order instead addresses a different condition: apply an explicit route reject before a broad default permit condition. It would instead require you to order route-policy clauses so the narrow deny is evaluated first, not the stated goal to carry a subscriber IPv4 service over an IPv6-only access network.

BGP remote AS alignment instead addresses a different condition: form an external BGP peering between provider and customer autonomous systems. It would instead require you to configure each peer with the other's correct remote AS and IP reachability, not the stated goal to carry a subscriber IPv4 service over an IPv6-only access network.

The proposed step is for CGNAT address sharing logging, whose purpose is to serve multiple IPv4 subscribers from shared public address resources.

The observation would verify CGNAT address sharing logging under the separate requirement to serve multiple IPv4 subscribers from shared public address resources. It does not demonstrate the needed DS-Lite IPv4 transport over IPv6 result: IPv4 applications work through the IPv6 access link and AFTR service.

This defect belongs to CGNAT address sharing logging, where the affected outcome is to serve multiple IPv4 subscribers from shared public address resources. It is not the direct failure mode identified for the DS-Lite IPv4 transport over IPv6 design in this case: NAT64 is substituted even though the client stack expects native IPv4 packets.
