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.

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.

Configure next-hop backup through policy-based routing on an AR router
If multiple carriers are available on a network, configure next-hop backup to keep network connectivity for intranet users and improve network robustness. Run the redirect backup-nexthop ip-address command in the traffic behavior. For details about the configuration of specific policy-based routing, see the URL: Example for Configuring Interface PBR.
