Greetings. I am trying to use ISI RSVP to make some layer3 reservations. My problem is that RSVP refuses to configure the queues with an "RNETLINK answers: invalid argument" error. Even if I try to setup the filter with tc command, I get the same error. I already tried to load all the modules necessary, rsvp and rsvp6 included, but I still got the same error. Can someone help me? Is the rsvp or rsvp6 filters working on 2.6.X kernel versions? Thanks in advance, Ricardo Duarte INESC Porto, Potugal
