Whether the firewall supports forward policy-based routing

43

The firewall supports forward policy-based routing.
If an outbound interface is configured for a policy-based route, the firewall determines whether the interface is Up. If yes, the firewall forwards a received packet based on the policy-based route. If no, the policy-based route does not take effect, and the firewall looks up the FIB table for a matching route for packet forwarding based on the destination IP address of the packet. If a next-hop address is configured for the policy-based route, the firewall looks up the FIB table based on the next-hop IP address. If a match is found, the firewall forwards the packet based on the policy-based route. If no match is found, the policy-based route does not take effect, and the firewall looks up the FIB table for a matching route for packet forwarding based on the destination IP address of the packet.

How does the device forward packets using policy-based routing
In earlier versions of V200R002C00, policy-based routing takes effect only for traffic delivered by the local device. To select routes for forwarding traffic, configure the redirect function. In V200R002C01 and later versions, policy-based routing (PBR) is categorized into local PBR, interface PBR, and smart policy routing (SPR). Local PBR takes effect only for traffic delivered by the local device and interface PBR takes effect only for traffic forwarded by the device.

Local PBR takes effect only for traffic delivered by the local device, interface PBR, and smart policy routing take effect only for traffic forwarded by the device.

Matching sequence of policy-based routes
Policy-based routes are matched based on their node sequence numbers in ascending order.

Differences between policy-based routing and default routing
The operation object of policy-based routing is packets. Even if a routing table is available, packets are not forwarded according to the routing table, and they are forwarded based on a policy according to requirements. According to the conventional routing and forwarding principle, packets are forwarded according to the destination addresses of the packets. Nowadays, more and more users expect that packets are forwarded and routed according to their defined policies on the basis of the conventional routing and forwarding. Policy-based routing enables the network administrator to formulate routing policies according to the source and destination addresses of packets, packet size, and link quality in order to change the forwarding paths of packets and meet user requirements.
