Don't be fooled by the names anymore! The difference between Policy-Based Routing and Routing Policy
Hey folks! Today let’s break down two tech terms that look like twins but are worlds apart—Policy-Based Routing (PBR) and Routing Policy.
Even seasoned network engineers trip up over these, but after reading this, you’ll be like: "Is that all? Nailed it!"

01 Basic definition
Policy-Based Routing (PBR): The Intelligent Sorting Assistant
Core task: Determine which route to take based on the package type (data characteristics).
Classic Configuration:
VIP Express (Video Conferencing Traffic) → Priority via Express Lane (High-Speed Dedicated Line)
Regular Parcels (File Downloads) → Dump onto Standard Link (Basic Connection)
Mantra: "Path up or down? Route by the rules—PBR’s got this!"
Routing Policy（RP）: The City Planning Commission of Networks
Hidden Supermove: Tweak the GPS algorithms (Routing Table Generation Logic)
Pro Gamer Move:
➥ Block pothole-filled shortcuts (Filter Specific Routes)
➥ Boost highway ads (Set Route Priorities)
Endgame: "All packets shall obey my traffic masterplan!"
02 Comparison Table: A Table to Clearly Distinguish Who's Who
Comparison Items | Policy-Based Routing (PBR) | Routing Policy（RP） |
Decision-making Level | Intervention during forwarding | Intervention before route calculation |
Impact Scope | Single data flow | Global routing table |
03 Practical scenarios: When should we use whom?
Scenario 1: Branch office accesses HQ via dedicated line, all other traffic uses the internet
→ Pick PBR: Intercepts traffic targeting HQ IPs → redirects to dedicated line interface
Scenario 2: Block a department from accessing external servers
→ Pick Routing Policy: drops routes to that server in BGP/OSPF → global policy enforcement
