Interface PBR

Interface PBR

Interface PBR applies only to packets received from other devices, but not to locally generated packets such as local ping packets.

Implementation

Interface PBR is implemented based on the redirect action configured in a traffic behavior and takes effect only on the inbound packets. By default, a device forwards packets to the next hop found in the routing table. If interface PBR is configured, the device forwards packets to the next hop specified by interface PBR.

When the device forwards packets to the next hop specified by interface PBR, the device triggers ARP learning if it has no ARP entry corresponding to the IP address of the specified next hop. If the device cannot learn this ARP entry, it forwards packets to the next hop found in the routing table. If the device has this ARP entry, it forwards packets to the next hop specified by interface PBR.
