 Bidirectional Forwarding Detection (BFD) is a unified network-wide detection mechanism used to quickly monitor the forwarding connectivity status of links or IP routes within a network.  When certain links do not provide hardware detection, applications rely on the upper-layer protocol's own Hello message mechanism for fault detection.

BFD Configuration

 Monitor Link is an interface linkage solution that triggers changes in the up/down state of downstream interfaces based on the changes in the up/down state of a monitored device's upstream interface.  This triggering subsequently leads to topology protocol switches on downstream devices.

Monitor-Link Configuration

 TRACK In order to further improve network reliability, redundancy protection methods are commonly used in practice, where two devices backup each other and can also share the workload.  When one of the devices experiences a link failure, the other device can take over to continue forwarding user traffic.

TRACK and SLA Configuration

 With the rapid popularization of networks and the deepening of related applications, various value-added services (such as IPTV, video conferencing, etc. ) have begun to be widely deployed.
