Overview of Redirection
Redirection is the process of redirecting packets that match traffic classification rules to a different destination.
The device supports the following redirection functions:
- Redirection to the CPU: redirects packets to the CPU.
- Redirection to an interface: redirects packets to a specified interface by which packets need to be processed or through which packets are sent to a specified device.
- Redirection to a next hop address: redirects packets to a next hop address when the received packets need to be processed by a downstream device. This function is valid for only Layer 3 packets and can be used to implement PBR. For details about PBR, see PBR Configuration in the S2720, S5700, and S6700 V200R019C10 Configuration Guide - IP Unicast Routing.
