5.5.1 Establishing the Configuration Task

Before associating the BFD session status with the sub-interface status, familiarize yourself with
the applicable environment and complete pre-configuration task of configuring a single-hop
BFD session and data preparation.
Applicable Environment
In the networking in which high reliability is required and a great number of services are
configured on the sub-interface, you need to set up BFD sessions to verify the connectivity of
the main interface link. In addition, you need to configure the association between the BFD
status and the sub-interface status. Thus, you can enhance the reliability of the service on the
sub-interface and save session resources.
