| Before FRR is ready, we will use static configuration to set SIDs and apply policy for TE. It enables basic SRv6 operation and populates SRv6 into ASIC, allows SRv6 data plan forwarding. More complicated SRv6 policy can be enabled when SRv6 is fully supported in FRR and passed from FRR to fpmsyncd. |

Can you explain more on controller role in the picture? Do we have separation of the route management between controller and FRR? If both can operate on same route entry and controller is doing update. We need more explanation on how to coordination is handled between these two. e.g. removing route entries shared by controller and FRR..

@caizhenghui-juniper Thanks for reviewing the HLD. For phase 1, the controller is supposed to avoid route conflicts with FRR. This can be achieved by using different VRFs or prefixes between routes from controller or FRR. For phase 2, all routes update need to go through FRR, who will take care of the route conflicts.

The details of srv6mgr modifying the ROUTE_TABLE is not clear. Please have it captured in detail and with flow diagram.

In our previous discussion, it was decided to have controller to push routes to APP_DB directly thereby avoiding srv6mgr altogether. Also the config_db entries can be directly subscribed by srv6orch similar to fgnhgorch. Please address this

@prsunny Hi Prince, yes we are avoiding srv6mgr as this was stop gap until FRR integration which is planned for next release. Agree that hence srv6 mgr can be avoided and have controller push the routes to APP_DB. We have these changes reflected in the HLD now and also in the diagram. Thanks.
