DLDP Configuration Example
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. All
the ports involved operate in mandatory full duplex mode, with their rates all being 1,000 Mbps.
z Suppose the fibers between Switch A and Switch B are cross-connected. DLDP disconnects the
unidirectional links after detecting them.
z After the fibers are connected correctly, the ports shut down by DLDP are restored.
