5.9 Configuring the Delay of a BFD Session to Go Up

In special scenarios, the delay of a BFD session to go Up is configured to prevent traffic loss as
a route protocol becomes Up later than an interface.

5.9.1 Establishing the Configuration Task

Before configuring the delay of a BFD session to go Up, familiarize yourself with the applicable
environment, complete the pre-configuration tasks, and obtain the data required for the
configuration. This will help you complete the configuration task quickly and accurately.
Applicable Environment
If BFD is Up on a network, the interface bound to BFD goes Up, allowing traffic to switch back
to the interface. As a routing protocol goes Up later than the interface status, no route is available
for traffic to switch back. As a result, traffic is dropped. The time when the routing protocol goes
Up and the time when the interface goes Up must be synchronous.
Pre-configuration Tasks
Before configuring the delay of a BFD session to go Up, ensure that the router runs normally.
Data Preparation
To complete the configuration, you need the following data.
No.
