APBR: Midstream APBR

Junos OS supports advanced policy-based routing (APBR) with an additional enhancement to apply the APBR in the middle of a session (midstream support). With this enhancement, you can apply APBR for a non-cacheable application and also for the first session of the cacheable application. You can fine-tune the outbound traffic with APBR configuration (for example, limiting route changes and terminating sessions) to avoid issues such as excessive transitions due to frequent route changes. The enhancement provides more flexible traffic-handling capabilities that offer granular control for forwarding packets.
