Hello, (I'm also reply to the new mpls-linux-general list at sourceforge, you should have been added, please use this list in the future) On Thu, Nov 30, 2000 at 06:29:35PM +0100, Mudra Peter wrote: > Hi! > > I'd like to compare the mpls implementation to the "normal" best effort > parameters.

This API would be used by LDP or RSVP-TE (if someone chooses to implement it, hint hint) If you want to manually setup LSPs this is the tool to use. If you want to dynamically setup LSPs use LDP. > The other thing: how to measure the throughput? How can i observe, > when mpls labeled packet go trough the network? I'm not sure what you mean. Do you want to see the label stack? Right now, I do it by hand, by using tcpdump. Maybe ethereal has support for it now. > What is the curent configuration? > Ex: mpls-linux0.601 + lilnux-2.4.0-test10 + ldp-portable0.060. > Do they work together, or should i use other versions? I would change it to mpls-linux-0.700 linux-2.4.0-test11 and the soon to be release ldp-portable0.065 :-) When you say "work" what do you mean? ;-) > And what can i do when compiling the ldp_linux? How to run it ? There is a small amount of help. Run ldp_linux as root (hit enter and then type ? and hit enter) I just realize that the README for ldp_linux doesn't contain any info how to run it. I will write up a README and add it to ldp-portable-0.065. For now: Start up ldp_linux: ./ldp_linux Add a global object: prompt> add global 172.16.0.1 Add an interface: prompt> add interface eth1 Show the database of sent/received labels: prompt> show database Show the list of established sessions: prompt> show session Show the list of discovered adjacencies: prompt> show adj That should get you started. I will write a more complete doc. Jim -- James R. Leu |
