HI,
I am a little confused as to which role each of the following plays or where it is used in forwarding decisions on different platforms ;
- CEF
- Netflow feature accelerate
- MLS
My understanding (that's what I want to confirm) is that some features use netflow for forwarding, some use cef/fib and depending on which platform like the 6500 may use hardware acceleration for ACLs.
So, it looks like depending on which platform and which feature you use, different forwarding technologies might be used.
Is there a good document that would describe roles/relationship between cef/Netflow feature acceleration and mls ?
Also, is cef used at all for any layer 4 forwarding decisions or does this involve netflow feature acceleration ?
Thanks !
