3.10 Configuring Association Between BFD Status and Sub-
interface Status
Association between BFD status and sub-interface status implements fast route convergence.
This function is applied to only to the single-hop BFD session bound to default multicast IP
address.
Applicable Environment
If your network requires high reliability and a lot of services are configured on sub-interfaces,
set up a BFD session to detect connectivity on the main interface and associate the BFD status
to sub-interfaces. This function improves service reliability on sub-interfaces and reduces the
number of BFD sessions.
Pre-configuration Tasks
Before associating BFD status with interface status, complete the following task:
