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
that has high requirements for
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.

Configuration Roadmap
The configuration roadmap is as follows:
1.
Configure a BFD session on Router A.
2.
Configure a BFD session on Router B.
3.
Associate the BFD status with the sub-interface status when the BFD session on Router A
is Up.
4.
Associate the BFD status with the sub-interface status when the BFD session on Router B
is Up.
Data Preparation
To configure the association between the BFD status and the sub-interface status, you need the
following data:
l
IP address of the main interface on the remote end of a BFD session
l
Local interface sending and receiving BFD control packets
l
Local discriminator and remote discriminator of the BFD session
