Hi! Please advise me an IOS for 7200/NPE-G1 which can stable do jitter related SAA/SLA tasks in VRF enabled environment. Which IOS are best for responder and probe? Both of them are 7200 routers without any load. I have failed with 12.3(9): rtr responder got stuck while run 16+ simultaneous probes.. :( -- Dmitry Kiselev
