Can you see bellow, this is established LDP session information to use xconnect command.
Peer LDP Ident: 192.168.1.1:0; Local LDP Ident 192.168.2.2:0
TCP connection: 192.168.1.1.646 - 192.168.2.2.12762
Targeted Hello 192.168.2.2 -> 192.168.1.1, active, passive;
holdtime: infinite, hello interval: 2222 ms
I quess why holdtime of targeted hello is infinite and interval is 2222ms.
I was configuring two command.
tag-switching tdp discovery directed-hello interval 5
tag-switching tdp discovery directed-hello holdtime 20
this is verifying sh mpls ldp parameters
command. printed information is right.
Discovery targeted hello: holdtime: 20 sec; interval: 5 sec
I want to know this problem.
Somebody help me?

holdtime: infinite and interval is 2222ms are parameters pertaining to the TCP session and are not settable.
You want to look at the end of the "show mpls ldp nei detail" output to see the parameters that you have set.
R1#sh mpls ldp nei det
Peer LDP Ident: 4.4.4.4:0; Local LDP Ident 1.1.1.1:0
TCP connection: 4.4.4.4.11003 - 1.1.1.1.646
State: Oper; Msgs sent/rcvd: 100/99; Downstream; Last TIB rev sent 16
Up time: 00:13:09; UID: 2; Peer Id 0;
LDP discovery sources:
Targeted Hello 1.1.1.1 -> 4.4.4.4, active;
holdtime: infinite, hello interval: 3333 ms
Addresses bound to peer LDP Ident:
4.4.4.4 192.168.24.2
Peer holdtime: 30000 ms; KA interval: 10000 ms; Peer state: estab <++++++ Here they are.

Hope this helps,

Actually, I was looking at the wrong info. Let me get back to you on this.
Thanks,

You rather want to look at the output of the "sh mpls ldp dis det" command to see what was negotiated holdtime between the two peers. The lowest holdtime value is taken. The interval is derived from the holdtime unless a lesser value is specified via the "mpls ldp discovery targeted-hello interval" command.
Hope this helps,

Thanks your advice.
I have one more question.
Why targeted hello holdtime is infinite ?
