[j-nsp] Traffic Engineering via LSP

juniper's default policy is this:

for all active BGP routes, if there is an LDP- or RSVP-signaled LSP to 
the BGP next hop - use it.

And I suppose you're experiencing this default behaviour. Working around 
this is not so simple - one option might be to give the remote end a 
second loopback address (that is not normally used as bgp next hop) and 
then build the LSP to that secondary address. That should keep your 
normal BGP traffic out of the LSP.

Kind regards,

Felix
