IV. DLDP implementation
1) If the DLDP-enabled link is up, DLDP sends DLDP packets to the peer device, and
analyses and processes DLDP packets received from the peer device. DLDP in
different status sends different packets.
Table 1-4 Types of packets sent by DLDP
DLDP status Packet types
Active Advertisement packets, including those with or without RSY tags

z In authentication mode, DLDP authenticates the packets, and discards those do
not pass the authentication.
z DLDP processes the received DLDP packets.
