How does the device forward packets using policy-based routing

9

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.

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

Whether the firewall supports forward policy-based routing
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.

Does an AR router support policy-based routing
All models of AR routers support policy-based routing.

How to configure OSPF to filter routes based on a routing policy
OSPF can use routing policies to filter routes. By default, OSPF does not filter routes. To configure OSPF to filter the routes to be received, run the filter-policy import command. To configure OSPF to filter the routes to be sent, run the filter-policy export command. You can use one of the following routing policies: 1. Basic ACL 2. Advanced ACL 3. IP prefix list 4. Route-policy

Does policy-based routing of an AR router need a license
Policy-based routing (PBR) selects a route based on user-defined policies. PBR falls into local policy routing, interface policy routing, and smart policy routing (SPR). - Neither local policy routing nor interface policy routing needs a license. - Smart policy routing (SPR) needs a license.

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