[j-nsp] LDP issues

[Christian Malo]

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
