After EFM is associated with IPv4 static routes, the system determines whether to activate the static routes based on the EFM session status.
After EFM is associated with IPv4 static routes, the system responds to the interface Up or Down event that is triggered by the change of the EFM OAM extension status and determines whether to activate static routes. This mechanism controls route advertisement and ensures that the traffic from the remote end can be correctly forwarded.
EFM is used on links between customer edges (CEs) and user-end provider edges (UPEs) on a metropolitan area network (MAN). It helps maintain the reliability and stability of connections between a user network and a provider network. EFM monitors and detects faults in P2P Ethernet physical links or simulated links. Using EFM on a user access network is recommended.
Before associating EFM with IPv4 static routes, complete the following tasks:
Configure link-layer protocol parameters and IP addresses for interfaces to ensure that the link layer protocol of each interface is Up.
Configure EFM OAM. For configuration details, see "Network Reliability" in HUAWEI NetEngine 8000 F Series Router Configuration Guide.

EFM is associated with IPv4 static routes in public network.
EFM is associated with IPv4 static routes in VPN network.
The configuration is committed.
Run the following commands to check the previous configuration.
Run the display efm session { all | interface interface-type interface-num command to check information about EFM OAM on a specified interface.
Run the display current-configuration | include efm command to check configurations of association between EFM and IPv4 static routes.
