DLDP packet type Function
Advertisement
Notifies the neighbor devices of the existence of the local
device. An advertisement packet carries only the local port
information, and it does not require response from the peer
end.
RSY-Advertisement
packets (referred to
as RSY packets
hereafter)
Advertisement packet with the RSY flag set to 1. RSY
advertisement packets are sent to request synchronizing the
neighbor information when neighbor information is not
locally available or a neighbor information entry ages out.
Flush-Advertisement
packets (referred to
as flush packets
hereafter)
Advertisement packet with the flush flag set to 1. A flush
packet carries only the local port information (instead of the
neighbor information) and is used to trigger neighbors to
remove the information about the local device.
Probe
Probe packets are used to probe the existence of a
neighbor. Echo packets are required from the corresponding
neighbor. Probe packets carry the local port information.
Neighbor information is optional for probe packets. A probe
packet carrying neighbor information probes the specified
neighbors; A probe packet carrying no neighbor information
probes all the neighbors.
Echo
Response to probe packets. An echo packet carries the
information about the response port and the neighbor
information it maintains. Upon receiving an echo packet, a
port checks whether the neighbor information carried in the
echo packet is consistent with that of itself. If yes, the link
between the local port and the neighbor is regarded as
bidirectional.
Disable
Disable packets are used to notify the peer end that the local
end is in the disable state. Disable packets carry only the
local port information instead of the neighbor information.
When a port detects a unidirectional link and enters the
disable state, the port sends disable packets to the neighbor.
A port enters the disable state upon receiving a disable
packet.
