Figure 6-8:
A Layer 2 switch exists between Switch A and Switch B.
Switch A, Switch B and Switch C run IS-IS.
BFD is configured to detect the IS-IS neighbor relationship between Switch A and Switch
B. When the link between Switch A and Switch B is faulty, BFD can fast detect the default
and report it to IS-IS.
