About This Chapter

A BFD session rapidly detects a link fault on a network.

5.1 Introduction

BFD rapidly detects communication faults between a local device and its neighbors. This

minimizes the impact of the faults on services.

5.2 Configuring Single-hop BFD

A single-hop BFD session rapidly detects faults on direct links over a network.

5.3 Configuring the BFD Passive Echo Function

By configuring the BFD passive Echo function, you can implement the interworking between

the devices that support the Echo function. This function is applicable to only single-hop BFD

5.4 Configuring the Association Between the BFD Status and the Interface Status

By associating the BFD session status with the interface status, you can trigger fast route

convergence. This function is applicable to only the BFD session that uses the default multicast

IP address to detect the single-hop link.

5.5 Configuring the Association Between the BFD Status and the Sub-Interface Status

By associating the BFD session status with the sub-interface status, you can trigger fast route

convergence. This function is applicable to the single-hop BFD session that detects default

multicast IP addresses.

5.6 Configuring the BFD to Modify the PST

By configuring a BFD session to modify the PST, you can speed up link fault detection by the

BFD session. This function is applicable to only single-hop BFD sessions.

5.7 Configuring the Multi-Hop BFD

By configuring a multi-hop BFD session, you can fast detect and monitor multi-hop links on a

5.8 Configuring a BFD Session with Automatically Negotiated Discriminators
