5 BFD Configuration
About This Chapter
A BFD session rapidly detects a link fault on a network.
5.1 BFD Overview
BFD, a uniform detection mechanism for an entire network, rapidly detects faults and monitors
the forwarding and connectivity of links or IP routes of the network.
5.2 BFD Features Supported by the S6700
This section describes the BFD features supported by the S6700.
5.3 Configuring Single-hop BFD
A single-hop BFD session rapidly detects faults in direct links over a network.
5.4 Configuring the Multi-Hop BFD
By configuring a multi-hop BFD session, you can fast detect and monitor multi-hop links of a
network.
5.5 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.
5.6 Adjusting BFD Parameters
Adjusting BFD parameters enables a BFD session to check links on a network effectively and
quickly.
5.7 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.
5.8 Maintaining BFD
This section describes how to maintain BFD by deleting BFD statistics, and monitoring BFD
operation.
5.9 Configuration Examples
This section provides several configuration examples of BFD.
