That helps me a lot. After login in more routers. It seems that some of them do runs RSVP. In some of the LSP's have got ldp-tunneling configured. The juniper web pages simply says "Enable the LSP to be used for LDP tunneling." However, after digging the juniper web sites, and some of my outdated in-house documents, it seems that it has something to do with load-balancing and hash calculation of the LSP's.

Re: [j-nsp] AS-PAth Prepend and Loop Command
Hi Reza - I did some testing in the lab to see what would happen if you tried to prepend someone elses AS to an announcement - and this is what I got. The peer would not come up, the traceoptions show : The peer will not come up stating : Jan 7 23:25:55.072684 BGP RECV Notification code 3 (Update Message Error) subcode 11 (AS path attribute problem) This is running Junos 8.5 R1.4 So to help your understanding remember you only prepend your own AS to others and AFAIK you cant prepend AS's that don't belong to you onto an announcement. I cant speak for other vendors, however I'm sure the implementation will be in accrodance to the RFC and they will get the same result. I encourage you to do some testing in the lab to understand this concept better..

Re: [j-nsp] bgp path
Sorry yet again I seem to be lacking my brain - what I meant to say was
in the example I posted I had a reject statement at the end so that I
would only be exporting any of my aggregate routes with the prepend.
This was a copy of one of my policies just to illustrate the prepend.
Sorry for any confusion, its late in the Uk and my brain has decided to
divide by zero :)

As a newcomer to JUNOS I'm stumbling a little on the policy
configurations (in particular for prepending.) This really seems to
spell it out better than the Juniper reference.
One question- The 'then accept;' statement after term 2 ... is it
necessary? If so, what is it doing that wouldn't happen if it was gone?
