I am using OSPF az IGP

sh mpls ldp parameters

Protocol version: 1

Downstream label generic region: min label: 16; max label: 524286

Session hold time: 180 sec; keep alive interval: 60 sec

Discovery hello: holdtime: 15 sec; interval: 5 sec

Discovery targeted hello: holdtime: 90 sec; interval: 10 sec

Downstream on Demand max hop count: 255

afaik, in frame mode MPLS loop detection is the task of the IGP. LDP loop detection is mainly for cell based MPLS, i.e. if you have ATM switches as LSRs. There LDP will setup the VC and loop detection is used.

So no worries, everything is just fine with your show output.
