Configuring session hold-time
The LDP entity on the interface sends Hello packets periodically to find out LDP
peer, and the established sessions must also maintain their existence by periodic
message (if there is no LDP message, then Keepalive message must be sent).

There are two types of LDP sessions: Basic and Remote. Basic session can be
established only on two direct-connect switches, while Remote session can be on
two switches which are not directly connected. You can only configure Basic
sessions in VLAN interface view and Remote sessions in remote-peer view.

Configure Basic session hold-time in VLAN interface view.
By default, the session-holdtime is 60 seconds and hello-holdtime is 15 seconds.
Configure Remote session hold-time in Remote-peer view.
By default, targeted-session-hold holdtime is 60 seconds, and the interval is 24
seconds; targeted-hello holdtime is 45 seconds and the interval is 13 seconds.

Configuring Hello transport-address
The transport-address discussed here refers to the address carried in the transport
address TLV in Hello messages. Generally, you can configure the transport-address
to the MPLS LSR ID of the current LSR, but you can also configure the
transport-address to other address flexibly as required by some applications.
