(Optional) Configuring the DLDP-Compatible Mode
Context
This configuration is required if the device works with the following Huawei switches to provide the DLDP function:
S8500
S7800
S6500
S5600 series
S5100-EI
S3900
S3500 series
S3100 series
DLDP can be configured on Layer 2 and Layer 3 Ethernet interfaces. By default, an Ethernet interface works in Layer 2 mode. Before configuring DLDP on a Layer 3 Ethernet interface, switch the Ethernet interface to Layer 3 mode.
In compatible mode, the default BPDU MAC address carried in a DLDP packet is 010F-E200-0001.
Procedure
- Run system-view
The system view is displayed.
- Run interface interface-type interface-number
The interface view is displayed.
- Run dldp compatible-mode enable
The DLDP compatible mode is enabled.
The DLDP compatible mode must be enabled or disabled on both the two interfaces.
- Run dldp compatible-mode local-mac mac-address
The DLDPDUs sent in the DLDP compatible mode contain MAC addresses.
After the DLDP compatible mode is enabled on the device, the remote device may discover multiple neighbors, which leads to DLDP flapping. The dldp compatible-mode local-mac command can prevent this problem.
At least one bit in the MAC address must be 0, and the MAC address cannot be a multicast MAC address.
