• Non Existent—No TCP connection is established.
• Initialized—A TCP connection has been established.
• OpenRecv—LDP has received an acceptable initialization message.
• OpenSent—LDP has sent an initialization message.
• Operational—An LDP session has been established.
Session Role Role the local LSR in the session, Active or Passive.
Session Up time Duration of the session in Operational state.
Max PDU Length
Maximum PDU length negotiated, in bytes.
Local—Maximum PDU length (in bytes) on the local LSR.
Peer—Maximum PDU length (in bytes) on the peer.
Keepalive Time
Keepalive time negotiated, in seconds.
Local—Locally configured Keepalive holding time, in seconds.
Peer—Keepalive holding time (in seconds) configured on the peer.
Keepalive Interval Keepalive interval in seconds.
Msgs Sent/Rcvd Total number of LDP messages sent and received.
KA Sent/Rcvd Total number of Keepalive messages sent and received.
Label Adv Mode
Label advertisement mode negotiated. The device only supports the DU
mode.
Graceful Restart
Indicates whether GR is enabled on the peer.
• On—Enabled.
• Off—Disabled.
Reconnect Time Reconnect time negotiated, in seconds.

Path Vector Limit Maximum Path Vector length configured on the peer.
Discovery Sources Discovery source of the LDP peer.
Targeted Hello
LDP peer discovered by the extended discovery mechanism.
• The address before -> (100.100.100.17 in this example) is the local LSR
ID.
• The address after -> (100.100.100.20 in this example) is the LSR ID of
the peer.
• (Active) indicates that the local LSR is the active end. It actively sends
Targeted Hellos to its peer.
• (Passive) indicates that the local LSR is the passive end. It passively
responds to the Targeted Hellos from its peer.
• (Active, Passive) indicates that the local LSR acts as both the active end
and the passive end.
GigabitEthernet2/0/2
Interface running LDP basic discovery. The device discovers the LDP peer
by sending Link Hellos out of the interface.
