Hi Guys,

I have posted this question in a few different forums but I have not had much 
luck with a response and I'm hoping someone can help me out. I recently 
upgraded to a triple-5meg DSL service setup with MLPPP here in Ontario Canada 
through a provider called Teksavvy. I chose FreeBSD as my o/s of choice and I'm 
using MPD5.5 to bond the connections. I believe they are using Juniper 
equipment on their end, not sure if it matters.

I have been using Linux for 15 years, and am an AIX Infrastructure Analyst by 
trade, but I am not very familiar with more advanced networking terms and 
technologies, and I am pretty new to FreeBSD.

I was wondering if someone could help me with the optimal values for my 
mpd.conf file - Max Transmit units, Max recieve unit, all that stuff. Here is 
what I've got going so far... Please note I am not on the freebsd-net mailing 
list so if you could CC me on the responses that would be great!

default:

load DSL

create bundle static B1

set link action bundle B1
open

create link static L3 pppoe
set auth authname x...@wiredhighspeed.com
set auth password xxx
set link max-redial 0
set link keep-alive 10 60
set pppoe iface fxp3
set pppoe service "teksavvy"
set link enable multilink
set link enable shortseq
set link disable protocomp
set link mrru 1500
# set link mru 1500
set link mtu 1492
set link bandwidth 5056000
set link action bundle B1
open

I can't really recall why I commented the MRU values - I think they defaulted 
to 1500 anyway. I adapted the config from a fast 2 Line setup posted in another 
forum around here. When I tested it as two lines, it was definitely "as fast as 
it could go". Not as impressed with the 3 line setup.

Any advice or direction on this would be greatly appreciated.

Thanks
