This is not enough.
You must have LDP egress-policy and include these loopbacks there too

Thanks Alex,
I had already redistibuted all my loopback into my IGP and all were reachable

You should have remote loopbacks also redistributed into LDP (if your
transport label is from LDP).
In JUNOS, this does not happen by default, you must have LDP egress-policy
for this to occur. By default, LDP announces only primary lo0.0 IP@.
Absent this, your L2circuits would show OL error (no outgoing label).
Before you ask, this is totally different to CSCO IOS which announces all
routes (bar BGP ones) as LDP FECs.

Hi Folks,
I have an exsisting L3 / L2 MPLS network with Cisco ASR on the Core as PE
router and Junper routers as PE router, i have been running l2circuits
sucessfully for some time now with out any problems using the below configs on
my PEs, I am running IS-IS as my IGP and BGP
[edit protocols l2circuit]

Now I am trying to extend these L2 circuits to anther MPLS Domain where we
have direct Gigabit fibre connection I am using the same concept and establish
ospf peering on the ASBR router with the remote ASN and redistributed my IGP so
my loopbacks are seen by the PEs on both sides of the domains and establish ldp
peering how ever the l2circuit is not coming up any help is appriciated as I
have been working on this more than 24hrs and think that i am now a bit clouded
