As shown in 

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.
