CEF is safe to a point. We're running it on 11.1CC(30), and it runs pretty well. We had memory leak problems in earlier versions on the 11.1CC train. I wouldn't use it for IMUXing, though. Check out Tiara Networks for their MLPPP engine. It's pretty nifty. CEF does a nice job of bringing the CPU down on a fully loaded 7513. That's all i'd use it for, until all the bugs get worked out. I had a bad experience using CEF on 12.0.5 in the type of situation you are describing. If a serial flapped, there was a small chance that the router CPU would go nuts, effectively making the router unmanageable. On a related note - Any ISPs out there using 12.0(s) yet in widespread release? -------------------------------------------------------------- Daniel L.
