Subject: Ethernet IP multicast maximum packet size
Date: Thu, 8 Sep 2005 17:35:02 +0200 [thread overview]
Message-ID: <5d0f6099050908083510aa9ab4@mail.gmail.com> (raw)
Hello developers,
I googled around all day, but did not find any satisfying answer. Is
there a maximum packet size when I use IP multicasting in a local
ethernet LAN? Or more precisely, does the multicast code in Linux
handle an IP fragmentation/defragmentation of a 63K UDP multicast
datagram, which is transmitted over an 1500bytes MTU ethernet? Or
should I stay on the safe edge and don't construct datagrams > 1500 so
I'll avoid fragmentation?
