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.
5.10 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 enables a BFD session to check links on a network 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 Globally
Configuring the TTL globally helps you connect the current device and a device running an early
version.
5.14 Configuring the Interval at Which Trap Messages Are Sent
The interval at which trap messages are sent is set, helping a device to suppress BFD trap
messages.
5.15 Maintaining BFD
This section describes how to maintain BFD by deleting BFD statistics, and monitoring BFD
operation.
5.16 Configuration Examples
The following sections provide several examples for configuring fast BFD link detection.
Familiarize yourself with the configuration procedures against the networking diagram. Each
configuration example consists of the networking requirements, configuration roadmap,
configuration procedures, and configuration files.
