Priorities of policy-based routing and default routing for an AR router


Policy-based routing has a higher priority than default routing. If policy-based routing and default routing coexist, only policy-based routing takes effect. After policy-based routing loses effect, default routing takes effect.

What are priorities of static routes and default routes of the AR router
Default routes can be statically configured or dynamically generated through dynamic routing protocols. If the default route is dynamically generated through dynamic routing protocols, its priority is the same as corresponding protocol. If the default route is statically configured, the default priority is 60, which is similar to that of the static route. Routes comply with the longest mask bit match principle. Specific routes are matched first, and then default routes are matched if the specific routes are not matched.

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.

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

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.
