Actually, CEF per-packet usually gives more throughput than MLPPP as there is less overhead. You ran run the Ts in the group as HDLC, rather than PPP. david raistrick wrote: On Fri, 14 Mar 2008, Nick Voth wrote: Thanks very much David. That definitely helps. Yes, our 2 T's are on the

However, with per-packet can you utilize the full speed of the 2 T's as if they were bonded like in MLPPP? That's the ultimate goal here. Memory says yes you get the full speed of 3Mb available with per- packet. It has been 8 years since I last used it, but I'm sure someone can back up

Actually I can vouch for per-packet working fine for sensitive applications like VoIP as long as your bonded lines are basically parallel in the sense they are the same technology over the same distance with the same characteristics, ie multiple T1 lines through the same carrier to the

Nick, I know that we mostly run multiple T1 links to customers over separate carriers for redundancy, thereby breaking the cef per-packet load-sharing for VoIP. If all your links will be over the same carrier and the same CT3, you should be okay. Also, your Adtran units running AOS 10 and up

We have some devices with management IPs in the 10.1.0.0/16 range that I manage and I needed to split up into two groups. All the devices were statically assigned an IP address in the form of 10.1.3.x/255.255.0.0, so I added two more secondaries for router interface fa0.5: 10.1.3.1/24 and
