1.5 Configuration Examples

This section provides a configuration example of DLDP.

1.5.1 Example for Configuring DLDP

Networking Requirements
As shown in
RX indicate the receive end, and TX indicates the transmit end. DLDP is enabled on the
interconnected interfaces. If the Rx fiber on Switch A fails, Switch A cannot receive optical
signals. In this case, XGE 0/0/1 of Switch A becomes Down and cannot send or receive any
packets. However, the Tx fiber on Switch B still sends optical signals, and Switch B can receive
optical signals because the Tx fiber on Switch A is working normally. Therefore, the link status
on Switch B is still Up. If Switch B does not receive any DLDP packet from Switch A within
the neighbor aging time, XGE 0/0/1 of Switch B changes to unidirectional state. To prevent
network faults, DLDP disables XGE 0/0/1 of Switch B.
