5.17.8 Example for Configuring the Association Between the BFD
Status and the Sub-interface Status
This example shows how to associate BFD session status and sub-interface status to improve
service reliability on sub-interfaces.
Networking Requirements
On the large-scale MAN Ethernet network shown in
reliability, a large number of services need to be configured on a sub-interface. BFD sessions
are configured to check the connectivity of the main interface link and the BFD status is
associated with the sub-interface status, improving the reliability of services on the sub-interface
and saving the session resources.
