Policy-based routing (PBR) provides a mechanism to configure permit/deny and reroute policies on the router. Permit/deny policies are similar to OVN ACLs, but exist on the logical-router. Reroute policies are needed for service-insertion and service-chaining.
We introduced a new table in the ingress pipeline of the Logical-router, between the "IP Routing" and the "ARP/ND resolution" table. In this talk, we'll go over the following:
* Need for policy-based routing * Why a new table in the Ingress pipeline in the logical-router * The rationale of the location of the new table * Demo of service-chaining using PBR
