[Khidzir_MN]

Description	This article describes how to enable Route health injection (RHI) for OSPF. It is maybe necessary to preconfigure other respective Virtual Server setup and OSPF setup and refer to the documentation at the end of this article for more information on configuring Virtual Server and OSPF.
Scope	FortiADC and FortiADC VM 6.2.0 or later.
Solution	Route health injection (RHI) allows advertising routes for the virtual server IP (VIP) addresses based on the health status of the respective virtual server. There is a requirement to advertise or remove the routes for the respective VIP addresses based on their health status to respective OSPF neighbors. There is no menu or option to enable the RHI. The respective VIP needs to be added under the OSPF Network. From GUI: Go to Network -> Routing -> OSPF (tab). Under Network, select Create New and add the respective VIP, select the respective Area and Save. Select Save again on the OSPF page. From the CLI: config router ospf     config network         edit 3            set prefix 10.50.12.105/32            set area 0.0.0.0         next     end end Below example when the VIP status is Healthy (The respective VIP is advertised): Below example of when the VIP status is Dead (The respective VIP is not advertised): Refer to this documentation for more information on configuring Virtual Server. Refer to this documentation for more information on configuring OSPF. Refer to this documentation for more information on RHI (Under Route health injection (RHI)).
