established. The static BFD session with automatically negotiated discriminators is applicable

to static routes.

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.

5.10 Configuring a BFD Session with the One-Arm Echo Function

By configuring a BFD session with the one-arm Echo function, you can fast detect and monitor

a direct link between a BFD-capable device and a BFD-incapable device.

5.11 Adjusting BFD Parameters

Adjusting BFD parameters allows a BFD session to check network links effectively and quickly.

5.12 Globally Configuring the Destination Port Number for the Multi-Hop BFD Control Packet

By configuring a global destination port number for multi-hop BFD control packets, you can

implement the interworking between the local device and a device running an earlier version,

and between a Huawei device and a non-Huawei device.

5.13 Configuring the TTL Function Globally

Configuring the TTL globally helps you connect the current device and a device running an early

5.14 Configuring the Interval for Trap Messages Are Sent

The interval at which trap messages are sent is set, helping a device to suppress BFD trap

5.15 Setting the Trap Threshold for Bandwidth Consumption in the Fast Packet Transmission

You can set the trap threshold for the bandwidth consumption in the fast packet transmission

channel on the LPU to control the bandwidth consumption.

5.16 Maintaining BFD

This section describes how to maintain BFD by deleting BFD statistics, and monitoring BFD

5.17 Configuration Examples

The following sections provide several examples for configuring fast BFD link detection. Each

configuration example consists of the networking requirements, configuration roadmap,

configuration procedures, and configuration files.
