1.3 DLDP Configuration Example
I. Network requirements
As shown in Figure 1-3,
z
Switch A and Switch B are connected through two pairs of fibers. Both of them
support DLDP.
z
Suppose the fibers between Switch A and Switch B are connected inversely.
DLDP disconnects a unidirectional link after detecting it.
z
When the network administrator connects the fiber correctly, the port shut down by
DLDP is restored.
