An animal-control HQ needs to discard traffic for a withdrawn public range during a spoofing incident. Which static-routing pattern is commonly used to blackhole that prefix?
Select an answer to reveal the explanation.
Short Explanation
Null0 is the network’s shredder chute—routes that point there make matching packets vanish on purpose. When a public range is withdrawn but spoofed traffic still shows up, a discard static is the clean blackhole. No need to invent fake next hops.
Full Explanation
A static route to Null0 installs a discard path so packets matching the prefix are dropped without needing a real next hop. That pattern is widely used for blackholing spoofed or withdrawn address space and for anchoring summaries. Pointing at a MAC, forcing every /32 through a floating default, or using PBR to an OSPF DR is operationally fragile or unrelated. Prefer a tightly scoped Null0 static and monitoring for the incident window.
