A Cloud Router learns route 10.2.0.0/16 from an on‑prem BGP peer. You also create a static route to 10.2.0.0/16 with priority 900. Which route will Google Cloud use to forward traffic to that prefix?

Google Cloud routing prioritizes static routes over dynamically learned routes (like those from BGP) when they have the same destination prefix. If multiple static routes exist for the same prefix, the one with the highest priority (lowest numerical value) is preferred. In this scenario, the static route to 10.2.0.0/16 with priority 900 will be chosen because static routes always take precedence over BGP-learned routes for identical prefixes. The BGP-learned route would only be used if no static route existed for that prefix. ECMP (Equal-Cost Multi-Path) is not applicable here as the routes are not considered equal cost due to their different types and explicit priority. Traffic will not be dropped; Google Cloud will always attempt to use the most specific and highest-priority route available.
