Refine PBR classification to match the intended source and destination selectors would not enable supported `ip local policy route-map` for the locally generated syslog flow.

Using the supported `always` option only when intentionally advertising default irrespective of a local installed default would not enable supported `ip local policy route-map` for the locally generated syslog flow.

Using a supported tracked or verified next-hop policy where appropriate and documenting normal-routing fallback would not enable supported `ip local policy route-map` for the locally generated syslog flow.

This test measures a different behavior: Test two source subnets to the same destination and inspect policy match counts and actual next hops. It does not establish the target outcome. For the documented fault, the direct acceptance test is: inspect `show ip local policy` and trace locally generated syslog packets over the intended monitored next hop.

This test measures a different behavior: Verify 0.0.0.0/0 external LSA presence and the upstream default route policy under failure tests. It does not establish the target outcome. For the documented fault, the direct acceptance test is: inspect `show ip local policy` and trace locally generated syslog packets over the intended monitored next hop.

This test measures a different behavior: Simulate next-hop loss and inspect path selection for matched traffic. It does not establish the target outcome. For the documented fault, the direct acceptance test is: inspect `show ip local policy` and trace locally generated syslog packets over the intended monitored next hop.

That diagnosis is supported by a different symptom: Inspection traffic bypasses the firewall although the ordinary FIB route is healthy. Here the recorded observation is: transit users match interface PBR as expected, but the router's own syslog packets still use the ordinary routing table. The applicable cause is: interface-applied PBR does not act on locally generated packets without a local PBR policy.

That diagnosis is supported by a different symptom: The default LSA disappears when the originating router loses its own RIB default route. Here the recorded observation is: transit users match interface PBR as expected, but the router's own syslog packets still use the ordinary routing table. The applicable cause is: interface-applied PBR does not act on locally generated packets without a local PBR policy.

That diagnosis is supported by a different symptom: Packets matching PBR are forwarded to an unreachable policy next hop until the route map changes. Here the recorded observation is: transit users match interface PBR as expected, but the router's own syslog packets still use the ordinary routing table. The applicable cause is: interface-applied PBR does not act on locally generated packets without a local PBR policy.

Tracking a policy next hop can improve fallback, but it does not make interface-only PBR apply to traffic generated by the router.

Refining ingress policy matches cannot fix the missing local policy hook for router-originated syslog packets.

That control reduces a separate risk: No effective ingress PBR policy matches the inspection source before ordinary route lookup. For the described design, the recurring risk arises from: interface-applied PBR does not act on locally generated packets without a local PBR policy. The specific required safeguard is: test locally originated versus transit traffic separately when changing policy routing and account for platform-specific TCP caveats.

Originate only the intended present RIB prefixes using valid BGP network or controlled redistribution policy would not address the need for refine PBR classification to match the intended source and destination selectors.

Applying a validated policy-based route map matching that source and setting a reachable policy next hop on the ingress L3 interface would not address the need for refine PBR classification to match the intended source and destination selectors.

Using a supported tracked or verified next-hop policy where appropriate and documenting normal-routing fallback would not address the need for refine PBR classification to match the intended source and destination selectors.

This test measures a different behavior: Test two source subnets to the same destination and inspect policy match counts and actual next hops. It does not establish the target outcome. For the documented fault, the direct acceptance test is: run matched and unmatched source/destination test flows to verify only SaaS traffic is steered.

This test measures a different behavior: Simulate next-hop loss and inspect path selection for matched traffic. It does not establish the target outcome. For the documented fault, the direct acceptance test is: run matched and unmatched source/destination test flows to verify only SaaS traffic is steered.

This test measures a different behavior: Check BGP next-hop resolution and RIB installation of the previously ineligible prefix. It does not establish the target outcome. For the documented fault, the direct acceptance test is: run matched and unmatched source/destination test flows to verify only SaaS traffic is steered.

That diagnosis is supported by a different symptom: Packets matching PBR are forwarded to an unreachable policy next hop until the route map changes. Here the recorded observation is: ordinary DNS traffic is sent to the special SaaS inspection next hop. The applicable cause is: the policy route-map match criteria are too broad for the documented service destination.

That diagnosis is supported by a different symptom: Inspection traffic bypasses the firewall although the ordinary FIB route is healthy. Here the recorded observation is: ordinary DNS traffic is sent to the special SaaS inspection next hop. The applicable cause is: the policy route-map match criteria are too broad for the documented service destination.

That diagnosis is supported by a different symptom: `show bgp` displays a received network but no usable installed route due to inaccessible next hop. Here the recorded observation is: ordinary DNS traffic is sent to the special SaaS inspection next hop. The applicable cause is: the policy route-map match criteria are too broad for the documented service destination.

That control reduces a separate risk: The PBR next-hop selection lacks health tracking or an available fallback path. For the described design, the recurring risk arises from: the policy route-map match criteria are too broad for the documented service destination. The specific required safeguard is: use counters and negative-match testing whenever PBR ACLs are expanded.

That control reduces a separate risk: The BGP NEXT_HOP attribute has no resolvable path in the routing table. For the described design, the recurring risk arises from: the policy route-map match criteria are too broad for the documented service destination. The specific required safeguard is: use counters and negative-match testing whenever PBR ACLs are expanded.

That control reduces a separate risk: No effective ingress PBR policy matches the inspection source before ordinary route lookup. For the described design, the recurring risk arises from: the policy route-map match criteria are too broad for the documented service destination. The specific required safeguard is: use counters and negative-match testing whenever PBR ACLs are expanded.

Configuring supported NTP authentication/key associations and restricting permitted peers where required would not configure a reachable, approved NTP server and appropriate authentication where supported.

Selecting supported bidirectional PIM with a properly established RP and designated-forwarder behavior would not configure a reachable, approved NTP server and appropriate authentication where supported.

Using a supported PTP grandmaster/transparent or boundary-clock design for the required timing accuracy would not configure a reachable, approved NTP server and appropriate authentication where supported.

This test measures a different behavior: Inspect PTP master selection, path delay and slave synchronization offset. It does not establish the target outcome. For the documented fault, the direct acceptance test is: compare NTP association reachability, synchronization state and offset to the authoritative time source.

This test measures a different behavior: Verify bidirectional group tree state and upstream/downstream forwarding from multiple sources. It does not establish the target outcome. For the documented fault, the direct acceptance test is: compare NTP association reachability, synchronization state and offset to the authoritative time source.

This test measures a different behavior: Check authenticated NTP association state and reject test replies from an untrusted peer. It does not establish the target outcome. For the documented fault, the direct acceptance test is: compare NTP association reachability, synchronization state and offset to the authoritative time source.

That diagnosis is supported by a different symptom: The device never reaches the target precision despite a healthy standard NTP synchronization. Here the recorded observation is: syslog timestamps drift because the switch is not synchronized to any valid NTP peer. The applicable cause is: the configured NTP source is unreachable or not accepted for synchronization.

That diagnosis is supported by a different symptom: The device synchronizes to an unauthorized source rather than the approved time reference. Here the recorded observation is: syslog timestamps drift because the switch is not synchronized to any valid NTP peer. The applicable cause is: the configured NTP source is unreachable or not accepted for synchronization.

That diagnosis is supported by a different symptom: A bidirectional group receives data only from one source because the network was built on incompatible source-tree assumptions. Here the recorded observation is: syslog timestamps drift because the switch is not synchronized to any valid NTP peer. The applicable cause is: the configured NTP source is unreachable or not accepted for synchronization.
