The explanation is in the command reference:
+++++++++++++++++++
mpls ldp discovery transport-address
+++++++++++++++++++
The default behavior when this command has not been issued for an interface depends on the interface type.
Unless the interface is a label-controlled ATM (LC-ATM) interface, LDP advertises its LDP router ID as the transport address in LDP
discovery hello messages sent from the interface.
If the interface is an LC-ATM interface, no transport address is explicitly advertised in LDP discovery hello messages sent from the
interface.

Subject: Cell Mode MPLS+LDP
Hi guys
I was just doing a lab and realised that when configuring MPLS cell-mode, no IGP is necessary or required to establish the LDP
neighborship like in frame-mode MPLS. What causes this between cell-mode vs frame-mode?
