Policy-based routing (PBR) is a mechanism for routing and forwarding based on user-specified policies. When a router forwards data packets, it filters the packets according to the configured rules, and then forwards the matched packets according to the specified forwarding policy.The PBR feature enables the device to formulate rules according to specific fields (source or destination IP address and protocol type) in the data packets, and forward the data packets from a specific interface.
Here are two typical application scenarios for PBR:
Flexible routing control
PBR allows network administrators to base their policies on user-defined policies such as source IP addresses, destination IP address, port number, protocol type, etc to determine the routing path of the packet, rather than just relying on the traditional routing table. This means that packets can be forwarded without exactly following the longest prefix matching principle.
Multiple exit options
For businesses with multiple Internet exits, the PBR can choose the most appropriate exit path based on a policy, such as destination, application type, or cost.
