DLDP Network Example
Network requirements
As shown in Figure 20-3 :
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
the unidirectional links after discovering them;
z
When the network administrator connects the fiber correctly, the ports taken down by DLDP are
restored.
