5.9 Configuring the Delay of a BFD Session to Go Up

In certain scenarios a BFD session is configured to go Up after a delay. Setting a delay for a
BFD session status change to Up can prevent traffic loss that occurs if an interface goes Up
before the routing protocol.

5.9.1 Before You Start

Before configuring a delay for a BFD session status change to Up, familiarize yourself with the
usage scenario, complete the pre-configuration tasks, and obtain the data required for the
configuration.
Applicable Environment
If BFD is Up on a network, the interface bound to BFD goes Up and traffic can be switched
back to the interface. If the interface goes Up before the status of the routing protocol changes,
no route is available for forwarding and switching back traffic. 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 BFD session status change to Up, ensure that the router runs
properly.
Data Preparation
To complete the configuration, you need the following data.
No.
