Scenario

Description

Task

Configure single-hop BFD

Single-hop BFD fast detects faults on the directly connected link.

Configuring Single-Hop BFD

Configure multi-hop BFD

Multi-hop BFD fast detects faults on the indirectly connected link.

Configuring Multi-Hop BFD

Configure static BFD with automatically negotiated discriminators

When the peer device uses dynamic BFD and the local device wants to communicate with the peer device and detect static routes, create a BFD session with automatically negotiated discriminators. This function is mainly used in scenarios where static routes are used to implement Layer 3 connectivity.

Configuring Static BFD with Automatically Negotiated Discriminators

Configuring BFD to Detect VPN Routes

BFD fast detects faults on the VPN routes.

Configuring BFD to Detect VPN Routes

Configure BFD association

Association between BFD and other protocols improves upper-layer application performance and fast detects faults on links.

Configuring BFD Association

Adjust BFD parameters

You can adjust BFD parameters so that the BFD session can fast detect faults on links.
