About This Chapter
A BFD session rapidly detects a link fault on a network.
3.1 Introduction to BFD
BFD rapidly detects communication faults between a local device and its neighbors. This
minimizes the impact of the faults on services.
3.2 Configuring Single-hop BFD
A single-hop BFD session rapidly detects faults on direct links over a network.
3.3 Configuring the Multi-Hop BFD
By configuring a multi-hop BFD session, you can fast detect and monitor multi-hop links on a
network.
3.4 Configuring a BFD Session with Automatically Negotiated Discriminators
A static BFD session with automatically negotiated discriminators is configured to check the
interworking between a device and another device on which a BFD session has been dynamically
established. The static BFD session with automatically negotiated discriminators is applicable
to static routes.
3.5 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.
3.6 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.
3.7 Adjusting BFD Parameters
Adjusting BFD parameters allows a BFD session to check network links effectively and quickly.
3.8 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.
