This concern applies to IGP LDP synchronization in a different scenario where operators need to avoid forwarding traffic onto a link before necessary MPLS labels are usable. For the deployed LDP address family transport approach, the relevant caution is instead that dual-stack label operation depends on platform feature compatibility.

This concern applies to TI-LFA node protection in a different scenario where operators need to protect a traffic flow against failure of the adjacent intermediate node. For the deployed LDP address family transport approach, the relevant caution is instead that dual-stack label operation depends on platform feature compatibility.

This concern applies to SRv6 VPN decapsulation in a different scenario where operators need to deliver SRv6-encapsulated VPN traffic into the correct customer routing table. For the deployed LDP address family transport approach, the relevant caution is instead that dual-stack label operation depends on platform feature compatibility.

RSVP bandwidth reservation instead addresses a different condition: reserve a bounded amount of link bandwidth for an MPLS TE LSP. It would instead require you to signal the required bandwidth and use correct TE admission information, not the stated goal to steer an MPLS TE tunnel over selected intermediate nodes rather than only IGP shortest path.

TI-LFA link repair instead addresses a different condition: protect an SR transport link using a loop-free post-convergence backup. It would instead require you to enable supported topology-independent LFA protection in the IGP, not the stated goal to steer an MPLS TE tunnel over selected intermediate nodes rather than only IGP shortest path.

LDP directly connected hello discovery instead addresses a different condition: form LDP adjacency on a provider core link carrying labeled traffic. It would instead require you to enable compatible LDP link discovery on both facing interfaces, not the stated goal to steer an MPLS TE tunnel over selected intermediate nodes rather than only IGP shortest path.

The proposed step is for RSVP bandwidth reservation, whose purpose is to reserve a bounded amount of link bandwidth for an MPLS TE LSP. It would not perform the necessary RSVP TE explicit path operation: configure an RSVP-TE tunnel with a suitable explicit-route object.

The observation would verify RSVP bandwidth reservation under the separate requirement to reserve a bounded amount of link bandwidth for an MPLS TE LSP. It does not demonstrate the needed RSVP TE explicit path result: the established tunnel follows listed hops and reserves the requested resources.

This defect belongs to RSVP bandwidth reservation, where the affected outcome is to reserve a bounded amount of link bandwidth for an MPLS TE LSP. It is not the direct failure mode identified for the RSVP TE explicit path design in this case: an ordinary LDP LSP follows IGP SPF instead of the required explicit path.

This concern applies to RSVP bandwidth reservation in a different scenario where operators need to reserve a bounded amount of link bandwidth for an MPLS TE LSP. For the deployed RSVP TE explicit path approach, the relevant caution is instead that strict hop constraints fail if an intermediate node or link becomes unavailable.

It would instead require you to configure an RSVP-TE tunnel with a suitable explicit-route object, not the stated goal to reserve a bounded amount of link bandwidth for an MPLS TE LSP.

TI-LFA SRLG protection instead addresses a different condition: avoid a repair path sharing a common fiber-risk group with the failed path. It would instead require you to enable supported SRLG-disjoint protection selection and valid risk-group topology data, not the stated goal to reserve a bounded amount of link bandwidth for an MPLS TE LSP.

SRv6 interworking gateway instead addresses a different condition: carry traffic between SRv6 and another provider service encapsulation domain. It would instead require you to deploy an interworking PE or gateway with explicit service and forwarding mappings, not the stated goal to reserve a bounded amount of link bandwidth for an MPLS TE LSP.

It does not demonstrate the needed RSVP bandwidth reservation result: the tunnel establishes only when links report sufficient reservable resources.

This defect belongs to RSVP TE explicit path, where the affected outcome is to steer an MPLS TE tunnel over selected intermediate nodes rather than only IGP shortest path. It is not the direct failure mode identified for the RSVP bandwidth reservation design in this case: the LSP is signaled across a path with inadequate TE unreserved bandwidth.

For the deployed RSVP bandwidth reservation approach, the relevant caution is instead that reservations do not by themselves eliminate all queuing or packet loss.
