Shivlu,
Can you include a "show mpls l2 vc det" from both PEs.
Thanks,

i am forwarding my configuration of both PE'S.
IST PE:-
interface FastEthernet0.801
description #### CE MPLS INTERFACE ####
encapsulation dot1Q 801
no snmp trap link-status
no cdp enable
xconnect x.x.x.x 801 encapsulation l2tpv3 pw-class shivlu
end
Second PE:-
interface GigabitEthernet0/2.801
description #### VARANASI MPLS INT ####
encapsulation dot1Q 801
no cdp enable
xconnect x.x.x.x 801 encapsulation l2tpv3 pw-class shiv
end
now when i run the command at pe2 i got the output like the given
VARANASI_PGCIL#sh l2tun session
%No active L2F tunnels
L2TP Session Information Total tunnels 2 sessions 3
LocID RemID TunID Username, Intf/ State Last Chg Uniq ID
Vcid, Circuit
3610 12208 30621 246, Fa0.246:246 est 01:02:36 2
3849 0 49847 890, Fa0.890:890 wt-tnl 00:00:01 129
3851 0 49847 801, Fa0.801:801 wt-tnl 00:00:00 58
my tunnels are always in the wt-tnl state.But this session is already established for 3 weeks not it got down and not able to up again.It is happening the same way with the clients.For the solution i have to migrate the clinet to another router where is worls fine.
The remote id is always 0 at one end.As i think that my core 7200 series router is not able to generate the tunnels and not assigning the local id number.
My hardware details are given below:-
7200 here i am getting problem

It looks like the l2tpv3 packets might not be getting from one PE to the other.
Is it possible to run a "debug xconnect"

Sincerly you should open a TAC case at your earliest. Since its in prodcution and a working config has stopped working.
In the meanwhile when you open the case, also check whether your end to end LSP is upon, using MPLS ping/trace.
