A stormwater bureau learns the same prefix from OSPF and from a floating static route. Which path installs in the RIB under default administrative distances?
Select an answer to reveal the explanation.
Short Explanation
Administrative distance is the trust score on the route report card. OSPF’s default score beats a floating static that’s intentionally hiked to 210 or similar. Keep the static in the back pocket for blackouts; let OSPF own the prefix while it’s healthy.
Full Explanation
When multiple routing sources offer the same prefix, Cisco IOS picks the source with the best (lowest) administrative distance. OSPF’s default AD (110) beats a floating static configured with a higher AD (commonly 200+), so the OSPF route installs while the IGP is up. A normal static at AD 1 would beat OSPF; “floating” means the static is deliberately worse so it only appears after OSPF withdraws. Equal CEF spraying of OSPF plus floating static is not the default outcome here.
