1.5 Configuration Examples
This section provides a configuration example of DLDP.
1.5.1 Example for Configuring DLDP
Networking Requirements
, two S3700s are connected through a pair of optical fibers. On a fiber,
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, Eth 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, Eth 0/0/1 of Switch B changes to unidirectional state. To prevent
network faults, DLDP disables Eth 0/0/1 of Switch B.

Configuration Roadmap
The configuration roadmap is as follows:
1.
Configure the interfaces at both ends to work in non-auto-negotiation mode.
2.
Enable DLDP.
3.
Set the operation mode of DLDP.
4.
Set the interval for sending Advertisement packets.
