DLDP Configuration Example

Network requirements
As shown in Figure
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.
Suppose the fibers between Switch A and Switch B are cross-connected. DLDP disconnects the
unidirectional links after detecting them.
After the fibers are connected correctly, the ports shut down by DLDP are restored.
