That control reduces a separate risk: A control-plane route existed but no eligible secure edge data-plane transport path was operational. For the described design, the recurring risk arises from: orchestration/validator reachability or device authorization is missing during initial discovery. The specific required safeguard is: test NAT, certificate, and control-connection bootstrap for each new transport/provider.

That control reduces a separate risk: Management-plane availability was confused with distributed edge data-plane forwarding. For the described design, the recurring risk arises from: orchestration/validator reachability or device authorization is missing during initial discovery. The specific required safeguard is: test NAT, certificate, and control-connection bootstrap for each new transport/provider.

That control reduces a separate risk: The edge lacks the expected OMP control-plane routes or policy, not a management dashboard login. For the described design, the recurring risk arises from: orchestration/validator reachability or device authorization is missing during initial discovery. The specific required safeguard is: test NAT, certificate, and control-connection bootstrap for each new transport/provider.

Using Cisco Catalyst SD-WAN Manager as the centralized management-plane system, not as the per-packet data forwarder would not address the need for forward encrypted user traffic between authorized SD-WAN edge routers across data-plane tunnels.

Using the Catalyst SD-WAN Controller as the control-plane peer that distributes routing and policy state to edge routers would not address the need for forward encrypted user traffic between authorized SD-WAN edge routers across data-plane tunnels.

Checking local VPN route redistribution and OMP advertisement toward the SD-WAN Controller would not address the need for forward encrypted user traffic between authorized SD-WAN edge routers across data-plane tunnels.

This test measures a different behavior: Verify a device template push and health telemetry in Manager while branch edges continue forwarding locally. It does not establish the target outcome. For the documented fault, the direct acceptance test is: capture TLOC/BFD and data-plane tunnel counters between edges while observing no user-data transit at Controller.

This test measures a different behavior: Verify the prefix in local VPN routing, OMP advertised routes and remote edge accepted routes in that sequence. It does not establish the target outcome. For the documented fault, the direct acceptance test is: capture TLOC/BFD and data-plane tunnel counters between edges while observing no user-data transit at Controller.

This test measures a different behavior: Inspect controller OMP peer status and accepted route advertisements from representative edge devices. It does not establish the target outcome. For the documented fault, the direct acceptance test is: capture TLOC/BFD and data-plane tunnel counters between edges while observing no user-data transit at Controller.

That diagnosis is supported by a different symptom: Tunnels may be up but remote VPN prefixes are not distributed to edge routes. Here the recorded observation is: application flows stop when an edge has no valid remote TLOC despite an OMP route being present. The applicable cause is: a control-plane route existed but no eligible secure edge data-plane transport path was operational.

That diagnosis is supported by a different symptom: A change engineer expects Manager to carry application packets and concludes the WAN is down when its UI is unavailable. Here the recorded observation is: application flows stop when an edge has no valid remote TLOC despite an OMP route being present. The applicable cause is: a control-plane route existed but no eligible secure edge data-plane transport path was operational.

That diagnosis is supported by a different symptom: The branch VPN prefix exists in its local RIB yet is absent from remote OMP routes. Here the recorded observation is: application flows stop when an edge has no valid remote TLOC despite an OMP route being present. The applicable cause is: a control-plane route existed but no eligible secure edge data-plane transport path was operational.

That control reduces a separate risk: The prefix was not injected into OMP or was rejected by control policy. For the described design, the recurring risk arises from: a control-plane route existed but no eligible secure edge data-plane transport path was operational. The specific required safeguard is: verify edge TLOC reachability independently of OMP route presence.

That control reduces a separate risk: The edge lacks the expected OMP control-plane routes or policy, not a management dashboard login. For the described design, the recurring risk arises from: a control-plane route existed but no eligible secure edge data-plane transport path was operational. The specific required safeguard is: verify edge TLOC reachability independently of OMP route presence.

Checking SD-WAN NAT traversal behavior and reachable TLOC public/private address mappings would not configure supported application-aware routing policy and BFD-based path measurements on SD-WAN edges.

Implementing a supported local TLOC extension between the two edges with required transport and routing settings would not configure supported application-aware routing policy and BFD-based path measurements on SD-WAN edges.

Mapping transport interfaces to intended supported SD-WAN colors and selecting TLOCs in policy would not configure supported application-aware routing policy and BFD-based path measurements on SD-WAN edges.

This test measures a different behavior: Check that the second edge advertises and can use the peer circuit's extended transport location. It does not establish the target outcome. For the documented fault, the direct acceptance test is: degrade one transport in a test and observe BFD statistics and selected TLOC change for voice while bulk traffic follows policy.

This test measures a different behavior: Inspect live local/remote TLOC color attributes and confirm the intended transport is selected. It does not establish the target outcome. For the documented fault, the direct acceptance test is: degrade one transport in a test and observe BFD statistics and selected TLOC change for voice while bulk traffic follows policy.

This test measures a different behavior: Correlate control-connection information with BFD/IPsec tunnel health across the translated transport. It does not establish the target outcome. For the documented fault, the direct acceptance test is: degrade one transport in a test and observe BFD statistics and selected TLOC change for voice while bulk traffic follows policy.

That diagnosis is supported by a different symptom: The backup router loses all transport connectivity when its directly attached ISP circuit fails. Here the recorded observation is: voice stays pinned to a high-loss circuit even though an eligible second circuit is healthy. The applicable cause is: the configured application SLA and transport selection policy are not steering flows from measured degraded path.

That diagnosis is supported by a different symptom: An Internet-only traffic policy chooses an MPLS TLOC after a template update. Here the recorded observation is: voice stays pinned to a high-loss circuit even though an eligible second circuit is healthy. The applicable cause is: the configured application SLA and transport selection policy are not steering flows from measured degraded path.

That diagnosis is supported by a different symptom: OMP peers are healthy while the remote branch has no established data tunnel through translated endpoints. Here the recorded observation is: voice stays pinned to a high-loss circuit even though an eligible second circuit is healthy. The applicable cause is: the configured application SLA and transport selection policy are not steering flows from measured degraded path.

NAT traversal and TLOC mapping can affect SD-WAN reachability, but this requirement is to switch carriers based on measured voice SLA degradation.

That control reduces a separate risk: Transport color classification or policy match does not reflect the physical circuit role. For the described design, the recurring risk arises from: the configured application SLA and transport selection policy are not steering flows from measured degraded path. The specific required safeguard is: review SLA thresholds and application classification after carrier changes.

A TLOC extension supplies transport connectivity; it does not select the better carrier from live loss and latency measurements.

Checking SD-WAN NAT traversal behavior and reachable TLOC public/private address mappings would not check local VPN route redistribution and OMP advertisement toward the SD-WAN Controller.

Using the Catalyst SD-WAN Controller as the control-plane peer that distributes routing and policy state to edge routers would not check local VPN route redistribution and OMP advertisement toward the SD-WAN Controller.

Forward encrypted user traffic between authorized SD-WAN edge routers across data-plane tunnels would not check local VPN route redistribution and OMP advertisement toward the SD-WAN Controller.
