Description
Specifies the state of LDP on the specified interface. Take note that MPLS must be
enabled otherwise LDP will be inactive.
Enable or disable the LDP log state here.
Enable or disable the LDP trap state here.
Enter the maximum back-off time used here. The LDP back-off mechanism prevents two
incompatibly configured LSRs from engaging in an endless sequence of session setup
failures. If a session setup attempt fails due to an incompatibility, the active LSR delays its
next attempt and then retries the session establishment. The delay begins at 15 seconds,
and it is increased exponentially with each successive failure until the maximum back-off
delay is reached. If a session cannot be established and the trap or log state is enabled,
LDP will send a trap or a log to the SNMP server to notify the session establishment
failure. This value must be between 120 and 65535 seconds.
Enter the LDP session keep-alive time here. LDP maintains a keep-alive timer for each
peer session. If the keep-alive timer expires without the receipt of an LDP PDU from the
peer, LDP will conclude that the peer has failed and will terminate the LDP session. Each
LSR sends keep-alive messages at regular intervals to its LDP peers to keep the
sessions active. This value must be between 15 and 65535 seconds.
Select the LDP transport address mode used here. The transport address is used to
establish the LDP TCP connection. By default, the LSR ID is used as the transport
address by all of the interfaces. If you select the transport address to a specific IP
address, this address is used as the transport address by all the interfaces. If you
configure the transport address to Interface, the IP address of each interface is used as
the transport address. Selecting LSR ID specifies that the LSR ID will be used as the
