Im trying to figure out the difference between MLPPP versus CEF? Which is truly better in simulating 1-large pipe using 6-8 DS1 (T1)???
When searching both this site & the main Cisco pages for MLPPP versus CEF I get one sentence at best What would a configuration look like on a 7200?Any help would be gratefully appreciated!

CEF can load share on a per-packet or per-flow basis over equal-cost links, while MLPPP can bond several links into a single virtual link. MLPPP works at a lower level and is therefore better at dividing load evenly, but it can cause higher CPU utiliztion on some platforms depending on the bandwidth of the links being bonded.
I think the best bet is usually to try MLPPP first if possible, and revert to per-packet CEF if MLPPP causes CPU usage problems.

Thanks for the quick reply! Just to be clear, does MLPPP spread up/down packets (by default) to all DS1's in the MLPPP virtual group?
Can you set per-packet versus per-session on MLPPP
like CEF?

Multilink PPP sends packets across the DS1 links in a round-robin fashion. The link below should be useful.
