admin@sw3# run show mpls ldp neighbor
AF ID State Remote Address Uptime
ipv6 2.2.2.2 OPERATIONAL 2::2 3d01h33m
ipv6 4.4.4.4 OPERATIONAL 4::4 3d01h32m
ipv6 5.5.5.5 OPERATIONAL 5::5 3d01h32m
admin@sw3# run show mpls ldp neighbor 2.2.2.2
AF ID State Remote Address Uptime
ipv6 2.2.2.2 OPERATIONAL 2::2 3d01h33mThe state of an LDP session are as follows:
PRESENT: This represents the initial state of the LDP session. In this state, both parties exchange Hello messages, and upon receiving the TCP connection establishment event, the session transitions to the INITIALIZED state.
INITIALIZED: This indicates that the LDP session is in the initialization phase.
OPENSENT: After entering the INITIALIZED state, the active party sends an Initialized message to the passive party and waits for a response.
OPENREC: After entering the INITIALIZED state, when both parties have received the Keepalive message from each other, the LDP session transitions to the OPERATIONAL state.
OPERATIONAL: This indicates that the LDP session has been successfully established.
