As you can see, I get the LDP route on ge-0/2/0 (6509).

Subject: Re: [j-nsp] LDP issues
This can also be an extended LDP discovery issue. Can you possibly share
your ldp configuration for the problem juniper routers, a show ldp database
| match "Input|L2CKT" , and a show l2circuit connections.
That's the simple setup I have
6500-sup720
|
|
|
m5 -------- m20------> bunch of other routers
I have ldp enabled on every router and the m20 has no problems setting up
l2circuits to every router except the m5 and 6500.
I noticed on the m5 that it doesn't have any LDP routes from the m20 but
has 1 from the 6509.
The configuration for both interfaces are the same and the mpls/ldp
configs are similar.

125 is the loopback address of the 6509
110 is the loopback address of the m20
124 is the loopback address of a router being the m20

Do you guys have any idea?
