Quote from: brad on April 08, 2008, 08:50:10 PMIt is irrelevant what I have.
Quote from: rlhdomain on April 11, 2008, 02:06:11 PMan MTU of 1500 is fine all the way to 100Mbpsso unless you need jumbo frames then don't worry
Quote from: eonesixfour on April 09, 2008, 11:56:40 PMI fail to see how, you might have an internet2 link which has a rather large MTU, then again if you are using a HE tunnel this isn't very likely. There is a very good reason for the MTU being set to what it is, since if you have a cable connection or PPPoA you'll most likely have a MTU of 1500, PPPoE is 1492 etc, to run IPv6 over IPv4 you have a bunch of overheads and bumping the MTU will just fragment packets possibly unnecessarily etc.
Quote from: rlhdomain on April 12, 2008, 11:36:53 PMhave you even looked at the set bandwidth of the tunnel?
Quote from: rlhdomain on April 12, 2008, 11:36:53 PMthe MTU only needs to be raised if the bandwidth is high and so is the quality
Quote from: rlhdomain on April 12, 2008, 11:36:53 PMon my cisco router if I type "show interface tunnel0" then I see the Bandwidth thats set and the MTU also your argument of fragmentation is invalid as a lower MTU gives less fragmentation and is more useful at lower bandwidth
Quote from: rlhdomain on April 12, 2008, 11:36:53 PMMTU= Maximum transmition unit= Max size for per packet in bytes= 1.5 kilobytes (or more accurately 1.46KB)and although your wan interface may be able to do 1500 without fragmentation it may not be able to do a tunnel with 1500
Quote from: rlhdomain on April 12, 2008, 11:36:53 PMsince the tunnels have differing MTU's I would assume its automaticly set by the HE point based on what can work with minimal fragmentation
Quote from: broquea on April 25, 2008, 10:03:54 PMFYI we are still looking into it as a configuration option inside the broker. There are just other things that require our attention at the moment.
Quote from: snarked on April 13, 2008, 04:50:20 PMOP: This sounds as if it's a problem with your specific configuration. My system reports a default mtu of 1480 as expected where the real interface is 1500. I don't see how you're getting a default of 1280. Please explain your hardware configuration. Something is different.
