That hazard arises in a separate case: An OSPF deployment puts all 600 remote access switches into area 0 and floods changes to every site. It is not the failure mode evidenced here.

That hazard arises in a separate case: Branch A and B redistribute external BGP into OSPF, then advertise resulting routes back into BGP at the opposite edge. It is not the failure mode evidenced here.

That hazard arises in a separate case: A branch OSPF design selects a totally stubby area but an application requires type-3 interarea routes rather than only the default. It is not the failure mode evidenced here.

That hazard arises in a separate case: Two OSPF neighbors on a routed core link are stuck in EXSTART/EXCHANGE and one endpoint uses an incompatible MTU. It is not the failure mode evidenced here.

That hazard arises in a separate case: A design team wants fast OSPF failure detection on long-running optical links without dropping stable adjacencies during occasional control-plane delay. It is not the failure mode evidenced here.

That hazard arises in a separate case: A campus plans IPv6 addressing with one /64 shared between two routed VLAN interfaces in different buildings. It is not the failure mode evidenced here.

That hazard arises in a separate case: A many-to-many trading network has multiple multicast senders and a scalable shared-tree forwarding requirement. It is not the failure mode evidenced here.

That hazard arises in a separate case: Network management of a branch uses a VPN over its sole primary WAN, and the organization reports no way to diagnose a provider outage. It is not the failure mode evidenced here.

That hazard arises in a separate case: A low-bandwidth remote management VPN carries huge nightly backup transfers that prevent emergency SSH access. It is not the failure mode evidenced here.

That hazard arises in a separate case: A campus has a fabric border but its external firewall cannot distinguish multiple endpoint VNs leaving the fabric. It is not the failure mode evidenced here.

That hazard arises in a separate case: A fabric site needs a guest wireless SSID without extending the guest Layer 2 domain across the whole enterprise. It is not the failure mode evidenced here.

That hazard arises in a separate case: An organization needs consistent segmentation across two SD-Access fabric sites connected by a routed MPLS service. It is not the failure mode evidenced here.

That hazard arises in a separate case: A financial organization leases a transparent point-to-point Ethernet service but requires independent routing at each site. It is not the failure mode evidenced here.

That hazard arises in a separate case: A branch uses IPsec overlay on broadband with 1400-byte effective MTU, but an application sends 1500-byte DF-set packets and stalls. It is not the failure mode evidenced here.

That hazard arises in a separate case: A network wants a hub-and-spoke topology for finance traffic but allows any-to-any policy for all service VPNs. It is not the failure mode evidenced here.

That hazard arises in a separate case: A global WAN telemetry system publishes a complete 10,000-interface snapshot every 100 ms although the target is only five-minute capacity planning. It is not the failure mode evidenced here.

That hazard arises in a separate case: An alerting system needs immediate notice of interface administrative status changes but only polls every five minutes. It is not the failure mode evidenced here.

That hazard arises in a separate case: A support dashboard needs regular CPU and interface-rate samples even when values remain unchanged. It is not the failure mode evidenced here.

That hazard arises in a separate case: A branch EIGRP router advertises remote routes back into its hub and occasionally becomes a transit path between hubs. It is not the failure mode evidenced here.

That hazard arises in a separate case: A BGP operator attempts to influence routes within one AS by changing the weight attribute only on one edge router. It is not the failure mode evidenced here.

That hazard arises in a separate case: An EIGRP deployment relies on a single aggregation router and an outage cuts off all downstream branches. It is not the failure mode evidenced here.

That hazard arises in a separate case: An NSF-capable router pair loses a control-plane process briefly and the design assumes all neighboring routers will preserve forwarding. It is not the failure mode evidenced here.

That hazard arises in a separate case: An SD-Access architect assumes the fabric's LISP control plane transports all user packets like a data-plane tunnel. It is not the failure mode evidenced here.

That hazard arises in a separate case: A campus has a fabric border but its external firewall cannot distinguish multiple endpoint VNs leaving the fabric. It is not the failure mode evidenced here.

That hazard arises in a separate case: Two hospitals need their existing Ethernet VLANs extended across a provider circuit but their engineers incorrectly request a routed L3VPN. It is not the failure mode evidenced here.

That hazard arises in a separate case: Two industrial sites require transparent delivery of a small set of Ethernet services and reject routing between their private LANs. It is not the failure mode evidenced here.

That hazard arises in a separate case: A customer needs private route separation for 12 branches over a shared provider backbone, not a single Ethernet broadcast domain. It is not the failure mode evidenced here.

That hazard arises in a separate case: An enterprise wants to expose a multicast stream to one receiver group but the original source uses a group address conflicting with a remote application. It is not the failure mode evidenced here.

That hazard arises in a separate case: Video and voice both use one strict-priority queue, causing voice jitter when video surges. It is not the failure mode evidenced here.

That hazard arises in a separate case: A campus uses DSCP EF for voice signaling, voice media, and backup traffic, causing priority queue overload. It is not the failure mode evidenced here.

That hazard arises in a separate case: An iBGP route reflector sees several candidate routes to the same destination but advertises only its best path to clients. It is not the failure mode evidenced here.

That hazard arises in a separate case: A branch EIGRP router advertises remote routes back into its hub and occasionally becomes a transit path between hubs. It is not the failure mode evidenced here.

That hazard arises in a separate case: An OSPF deployment puts all 600 remote access switches into area 0 and floods changes to every site. It is not the failure mode evidenced here.
