That's great info you provided Madman! Again, thanks much for your info!!! Thomas N. MADMAN wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Your correct, in fact MLS is enabled by default on the 6500. Main feature of a 5000, I don't think. I have seen people enable MLS on networks that were not even breaking a sweat, why? because they could and I'm simply saying that is not a good reason as I have fought to many MLS bugs to simply turn it on without good reason. Years ago there were many bugs in ip route-cache, (fast swithing) which hardly anyone thinks about anymore and someday MLS will be the same.

You can do it with an external router if you have an 10/100 blade that supports isl or dot1q trunking. or you gan get an rsm I believe or an nffc.

Well, please correct me if I am wrong. As my understanding, MLS is the main feature of Layer 3 switch (5000, 6000, 6500... not sure 4000 products). MLS allows hosts on different subnets talking at the wire speed after initially routed by the route processor.
