About This Chapter
A BFD session rapidly detects a link fault on a network.
5.1 Introduction to BFD
BFD rapidly detects the communication faults between the local device and its neighbor, which
minimizes the impact of the faults on services.
5.2 Configuring Single-hop BFD
A single-hop BFD session rapidly detects faults in 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
sessions.
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 of a
network.
5.8 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 is dynamically
established. The static BFD session with automatically negotiated discriminators is applicable
to static routes.
