>From the BGP section in the BSCN course book I "understand" that IP-Prefixlist are essentially nothing but another method of reaching the same goal as a distribute-list, but with a better performance and a more convenient user-interface. So they are (except for performance) functional the same, and there would be no reason to use a distribute-list instead of a ip prefix list ever.
I wonder whether this is also true in regards to on which interfaces they work on. Are IP-Prefix-lists indeed only used on incoming packets: so do they filter on incoming routes only? So, is it true than that IP-Prefix-lists are for filtering incoming updates, and distribute-lists (I'm talking BGP only) are able to filter both on incoming and outgoing packets? If so, is the matter of "better performance" for IP-prefix-list partly caused the fact that you don't hassle you router with packets you can kill on your incoming interface, which you can do with a outbound distribute-list route filtering? Plz explain presumming only BGP knowledge at the BSCN/CCNP level.
