When deploying BFD, you need to adjust some parameters so that it can better detect the network status. Which of the following statements is false about BFD optimization?

Options:

After a high priority is configured for BFD packets, BFD packets are preferentially forwarded.

To quickly learn about the network status and performance requirements, you can set the interval for sending BFD packets to the minimum value.

On a live network, some devices switch traffic only when a BFD session changes to the Up state. If a routing protocol goes Up later than an interface, no route is available for switching traffic back, leading to traffic loss. To resolve this issue, configure a delay to compensate for the time difference caused when the routing protocol goes Up later than the interface.

If a BFD session flaps, master/backup switchovers are frequently performed on the application associated with the BFD session. To prevent this, set the WTR time of the BFD session.
