This concern applies to VLAN tag pop at handoff in a different scenario where operators need to deliver untagged Ethernet to a customer while transporting a provider service tag. For the deployed G.8032 Ethernet ring protection approach, the relevant caution is instead that ring protection timers determine switchover and transient disruption.

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 G.8032 Ethernet ring protection approach, the relevant caution is instead that ring protection timers determine switchover and transient disruption.

This concern applies to traffic shaping smoothing in a different scenario where operators need to smooth an egress stream to a slower contracted handoff rather than dropping every burst. For the deployed G.8032 Ethernet ring protection approach, the relevant caution is instead that ring protection timers determine switchover and transient disruption.

E-LAN multipoint service instead addresses a different condition: make three remote customer interfaces members of one shared Ethernet broadcast domain. It would instead require you to provide an E-LAN bridge domain with all three authorized endpoints, not the stated goal to detect loss of Ethernet service connectivity between provider maintenance endpoints.

L3VPN overlapping subnet migration instead addresses a different condition: move a customer site to a new PE while another tenant uses the same IP block. It would instead require you to retain unique VRF and RD identities during the CE handoff change, not the stated goal to detect loss of Ethernet service connectivity between provider maintenance endpoints.

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 detect loss of Ethernet service connectivity between provider maintenance endpoints.

The proposed step is for E-LAN multipoint service, whose purpose is to make three remote customer interfaces members of one shared Ethernet broadcast domain. It would not perform the necessary Ethernet CFM continuity check operation: configure supported Ethernet connectivity fault management maintenance associations.

The observation would verify E-LAN multipoint service under the separate requirement to make three remote customer interfaces members of one shared Ethernet broadcast domain. It does not demonstrate the needed Ethernet CFM continuity check result: CFM continuity messages are received at each expected service MEP.

This defect belongs to E-LAN multipoint service, where the affected outcome is to make three remote customer interfaces members of one shared Ethernet broadcast domain. It is not the direct failure mode identified for the Ethernet CFM continuity check design in this case: only Layer-3 BGP is monitored while the Ethernet EVC is broken.

This concern applies to E-LAN multipoint service in a different scenario where operators need to make three remote customer interfaces members of one shared Ethernet broadcast domain. For the deployed Ethernet CFM continuity check approach, the relevant caution is instead that maintenance domain levels must be consistent between participants.

E-Tree root and leaf isolation instead addresses a different condition: allow a hub to reach remote leaves while preventing leaf-to-leaf communication. It would instead require you to configure an E-Tree rooted multipoint Ethernet service with leaf restrictions, not the stated goal to measure frame delay and loss across a provisioned Ethernet service.

EVPN MAC mobility control instead addresses a different condition: maintain forwarding when a customer virtual machine moves between EVPN access PEs. It would instead require you to apply MAC mobility and sequence handling for newly advertised locations, not the stated goal to measure frame delay and loss across a provisioned Ethernet service.

PE to CE BGP routing instead addresses a different condition: exchange customer subnet routes at a provider L3VPN boundary. It would instead require you to establish per-VRF BGP adjacency with suitable inbound and outbound policy, not the stated goal to measure frame delay and loss across a provisioned Ethernet service.

The proposed step is for E-Tree root and leaf isolation, whose purpose is to allow a hub to reach remote leaves while preventing leaf-to-leaf communication. It would not perform the necessary Y.1731 Ethernet delay measurement operation: enable suitable service OAM performance measurement on supported MEPs.
