DLDP neighbor state
A DLDP neighbor can be in one of the three states described in Table 6-7 .
Table 6-7 Description on DLDP neighbor states
DLDP neighbor state Description
Unknown
A neighbor is in this state when it is just detected and is being probed. A neighbor is
in this state only when it is being probed. It transits to Two way state or Unidirectional
state after the probe operation finishes.
Two way
A neighbor is in this state after it receives response from its peer. This state indicates
the link is a two-way link.
Unidirectional
A neighbor is in this state when the link connecting it is detected to be a unidirectional
link. After a device transits to this state, the corresponding neighbor entries
maintained on other devices are removed.

z For DLDP to work properly, enable DLDP on both sides and make sure these settings are
consistent: the interval to send Advertisement packets, DLDP authentication mode, and
password.
z DLDP does not process any link aggregation control protocol (LACP) events. The links in an
aggregation are treated as individual links in DLDP.
z For DLDP to operate properly, make sure the DLDP version running on devices on the two sides
are the same.
