Chris, http://mirror.switch.ch/rfc/4638.txt describes exactly the discussed topic.
btw it also states that no current IEEE standard supports the use of "jumbo frames" altough these are widely used in various network scenarios. stefan -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Christian Jouas Sent: Wednesday, June 13, 2007 11:30 AM To: [EMAIL PROTECTED] Subject: Re: [swinog] feedback on pppoe needed PPPoE (over Ethernet) ---> Ethernet max 1500 But I'm very curious if there are some non standards drafts over ethernet for such kind of applications ? Chris >>> "Spiess Bernd" <[EMAIL PROTECTED]> 12.06.2007 18:00 >>> thanx for the suggestions - the mtu path discovery problem was the reason why i asked. fyi: here in austria we have own access to the copper from "telekom austria" (colocation/"unbundling") we have our own dslaḿs and our own selection of cpés - so we can build or configure whatever we like. actually we use static ip on a switched layer 2 vlan-trunk environment. if possible we want to avoid PPPoA because we are no atm people. as i understand you correct mtu 1492 under PPPoE is still an issue in the mentioned cases. has anyone tried to build PPPoE with an MTU 1508 infrastructure ? bernd -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Fabian Wenk Sent: Tuesday, June 12, 2007 12:52 PM To: [EMAIL PROTECTED] Subject: [Spam] Re: [swinog] feedback on pppoe needed Hello Bernd Spiess Bernd wrote: > as i know many postings around the world regarding pppoe mtu problems > and advices to customers to reduce mtu on their clients down to 1492, > i wanted The problems with MTU 1492 could be on other places, eg. if a web server admin decides to filter ICMP on his server which will prevent Path MTU Discovery to work. For example this can have the effect, that from a website (hosted on a server which does not get the ICMP messages) the HTML part arrived (smaller then 1500 bytes), but the corresponding pictrures do not. I did once write a paper about the ADSL MTU problem, see "Swiss ADSL with PPPoA (and MTU 1500)" [1] for more informations.
