This concern applies to RSVP TE explicit path in a different scenario where operators need to steer an MPLS TE tunnel over selected intermediate nodes rather than only IGP shortest path. For the deployed SRLG diverse recovery approach, the relevant caution is instead that inaccurate SRLG inventory can falsely imply physical diversity.

This concern applies to SRGB consistent index mapping in a different scenario where operators need to ensure a prefix segment index resolves to an MPLS label on every transit node. For the deployed SRLG diverse recovery approach, the relevant caution is instead that inaccurate SRLG inventory can falsely imply physical diversity.

This concern applies to SR traffic-engineered SID list in a different scenario where operators need to force traffic through ordered provider waypoints while retaining ingress steering. For the deployed SRLG diverse recovery approach, the relevant caution is instead that inaccurate SRLG inventory can falsely imply physical diversity.

RSVP fast reroute detour instead addresses a different condition: protect a traffic-engineered LSP locally against a planned link outage. It would instead require you to configure FRR backup protection for the affected RSVP-TE link or node, not the stated goal to reserve traffic engineering resources separately for differentiated service classes.

PHP penultimate hop behavior instead addresses a different condition: avoid unnecessary label lookup at the final transport destination. It would instead require you to use the intended implicit-null or penultimate-hop-pop transport behavior, not the stated goal to reserve traffic engineering resources separately for differentiated service classes.

SR policy candidate preference instead addresses a different condition: select the desired segment-routing policy candidate path among valid alternatives. It would instead require you to set a coherent SR policy candidate path preference order, not the stated goal to reserve traffic engineering resources separately for differentiated service classes.

The proposed step is for RSVP fast reroute detour, whose purpose is to protect a traffic-engineered LSP locally against a planned link outage. It would not perform the necessary DS-TE class type allocation operation: apply the intended DS-TE bandwidth constraint model and class-type reservations.

The observation would verify RSVP fast reroute detour under the separate requirement to protect a traffic-engineered LSP locally against a planned link outage. It does not demonstrate the needed DS-TE class type allocation result: admission checks account for class-type availability on the candidate path.

This defect belongs to RSVP fast reroute detour, where the affected outcome is to protect a traffic-engineered LSP locally against a planned link outage. It is not the direct failure mode identified for the DS-TE class type allocation design in this case: all services reserve from one undifferentiated TE bandwidth pool.

This concern applies to RSVP fast reroute detour in a different scenario where operators need to protect a traffic-engineered LSP locally against a planned link outage. For the deployed DS-TE class type allocation approach, the relevant caution is instead that DS-TE capacity configuration requires consistent class-to-TE mapping.

MPLS-TE preemption priority instead addresses a different condition: allow higher-priority reservation requests to displace lower-priority capacity commitments. It would instead require you to configure setup and hold priorities consistently with the provider TE policy, not the stated goal to steer traffic classes over traffic-engineered tunnels according to service treatment.

PCE PCC path delegation instead addresses a different condition: allow a centralized PCE to update a delegated SR-TE candidate path on a headend. It would instead require you to establish PCEP PCE-PCC coordination with explicit delegation controls, not the stated goal to steer traffic classes over traffic-engineered tunnels according to service treatment.

IGP LDP synchronization instead addresses a different condition: avoid forwarding traffic onto a link before necessary MPLS labels are usable. It would instead require you to apply LDP IGP synchronization so route preference waits for LDP readiness, not the stated goal to steer traffic classes over traffic-engineered tunnels according to service treatment.

The proposed step is for MPLS-TE preemption priority, whose purpose is to allow higher-priority reservation requests to displace lower-priority capacity commitments. It would not perform the necessary CBTS tunnel service assignment operation: classify flows and apply class-based tunnel selection for the supported forwarding policy.

This defect belongs to MPLS-TE preemption priority, where the affected outcome is to allow higher-priority reservation requests to displace lower-priority capacity commitments. It is not the direct failure mode identified for the CBTS tunnel service assignment design in this case: all classes remain on a single default tunnel despite distinct path requirement.

For the deployed CBTS tunnel service assignment approach, the relevant caution is instead that fallback behavior matters if a class-specific tunnel becomes unavailable.
