# Policy Based Route

A Policy Based Route in Google Cloud lets you define advanced routing rules that go beyond standard destination-based routing. It allows traffic to be directed based on attributes such as source IP, protocol, or next hop. This enables fine-grained control over how traffic flows between networks, on-premises environments, and the internet, supporting use cases like traffic steering, service chaining, and custom egress routing.
