12.1.4 BFD Option
To protect key applications, a network is usually designed with redundant backup links. Devices need to quickly
detect communication failures and restore communication through backup links as soon as possible. On some links,
such as POS links, devices detect link failures by sending hardware detection signals. However, some other links,
such as Ethernet links, provide no hardware detection mechanism. In that case, devices can use the hello mechanism
of a protocol for failure detection, which has a failure detection rate of more than one second. Such a rate is too slow
for some applications. Some routing protocols, such as OSPF and IS-IS, provide a fast hello mechanism for failure
detection, but this mechanism has a failure detection rate of at least one second and is protocol-dependent.
To enter the BFD option interface, you can choose
