6.10.1 Before You Start

Before configuring BFD for OSPFv3, familiarize yourself with the usage scenario, complete
pre-configuration tasks, and obtain the required data. This can help you complete the
configuration task quickly and accurately.
Applicable Environment
To increase the convergence speed of OSPFv3 when the link status changes, you can configure
BFD on OSPFv3 links.
BFD keeps track of liveliness of network links and detects any faults in the links much faster
than the normal keep-alive protocols. When OSPFv3 is associated with BFD sessions, link
failures are notified immediately to OSPFv3 by BFD and OSPFv3 can take actions to perform
route calculation and converge in the new network topology.
