Tilbury, ON | 3-Line MLPPP DSL on BSD - MTU/MRRU/MRU?? Hi Guys,
I posted something in the Teksavvy forum 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. I chose FreeBSD as my o/s of choice and I'm using MPD5.5 to bond the connections.
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 concepts and 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 a dump of my file:
default:
load DSL
DSL:
create bundle static B1
set iface route default
set ipcp ranges 0.0.0.0/0 0.0.0.0/0
set ipcp enable req-pri-dns

set bundle disable bw-manage
set bundle links L1 L2 L3
set iface mtu 1492

# set link mru 1500

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! |
