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 node prefix SID forwarding approach, the relevant caution is instead that node SID path still follows IGP state and can change after failures.

This concern applies to MPLS label forwarding fault isolation in a different scenario where operators need to localize loss along a labeled transport LSP rather than at a customer application. For the deployed node prefix SID forwarding approach, the relevant caution is instead that node SID path still follows IGP state and can change after failures.

This concern applies to CBTS tunnel service assignment in a different scenario where operators need to steer traffic classes over traffic-engineered tunnels according to service treatment. For the deployed node prefix SID forwarding approach, the relevant caution is instead that node SID path still follows IGP state and can change after failures.

SR binding SID policy reuse instead addresses a different condition: allow an upstream router to steer into an established SR policy with one segment. It would instead require you to assign a binding SID that resolves to the intended local SR policy, not the stated goal to force an SR-MPLS packet through one particular egress adjacency.

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 force an SR-MPLS packet through one particular egress adjacency.

targeted LDP session instead addresses a different condition: maintain a directed label-distribution peer not connected by a single Ethernet hop. It would instead require you to configure the appropriate targeted LDP discovery and session authentication, not the stated goal to force an SR-MPLS packet through one particular egress adjacency.

The proposed step is for SR binding SID policy reuse, whose purpose is to allow an upstream router to steer into an established SR policy with one segment. It would not perform the necessary adjacency SID strict hop operation: insert the locally significant adjacency SID at the correct position in the label stack.

The observation would verify SR binding SID policy reuse under the separate requirement to allow an upstream router to steer into an established SR policy with one segment. It does not demonstrate the needed adjacency SID strict hop result: the packet follows the selected interface even if normal SPF prefers a different link.

This defect belongs to SR binding SID policy reuse, where the affected outcome is to allow an upstream router to steer into an established SR policy with one segment. It is not the direct failure mode identified for the adjacency SID strict hop design in this case: a node SID is used when an exact outgoing link is mandated.

node prefix SID forwarding instead addresses a different condition: steer a segment-routed packet to a particular node along its IGP shortest path. It would instead require you to use the node's advertised prefix SID in the appropriate segment list, not the stated goal to allocate routable prefixes to identify SRv6-capable nodes and behaviors.

LDP router ID transport stability instead addresses a different condition: keep an LDP session bound to a stable routable label-switching router identity. It would instead require you to configure a reachable loopback router ID as the LDP transport endpoint, not the stated goal to allocate routable prefixes to identify SRv6-capable nodes and behaviors.

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 allocate routable prefixes to identify SRv6-capable nodes and behaviors.

The proposed step is for node prefix SID forwarding, whose purpose is to steer a segment-routed packet to a particular node along its IGP shortest path. It would not perform the necessary SRv6 locator aggregation operation: configure a valid SRv6 locator prefix and corresponding IGP advertisement.

This defect belongs to node prefix SID forwarding, where the affected outcome is to steer a segment-routed packet to a particular node along its IGP shortest path. It is not the direct failure mode identified for the SRv6 locator aggregation design in this case: a SID is created without a routed locator leading traffic to that node.

SRv6 H.Encaps policy instead addresses a different condition: attach a segment routing IPv6 outer header to impose an explicit traffic-engineering path. It would instead require you to configure SRv6 encapsulation and the correct source and segment list, not the stated goal to process an SRv6 local End SID for transit forwarding to the next segment.

CBTS tunnel service assignment instead addresses a different condition: steer traffic classes over traffic-engineered tunnels according to service treatment. It would instead require you to classify flows and apply class-based tunnel selection for the supported forwarding policy, not the stated goal to process an SRv6 local End SID for transit forwarding to the next segment.

PCE constrained path computation instead addresses a different condition: delegate constrained SR-TE or MPLS-TE path computation to a path computation entity. It would instead require you to use a PCE-PCC architecture with agreed objectives and topology visibility, not the stated goal to process an SRv6 local End SID for transit forwarding to the next segment.

The proposed step is for SRv6 H.Encaps policy, whose purpose is to attach a segment routing IPv6 outer header to impose an explicit traffic-engineering path. It would not perform the necessary SRv6 End behavior operation: install the required local End function and forwarding information.
