I know in more recent Cisco IOS software (12.4.24T or later I think) the MTU of a GRE interface is that of the largest memory block on the box. I wouldn't be surprised if this is the same for loopbacks since they are a software concept. The logic behind this is that the largest frame the software interface can handle would be equal to the largest chunk of memory to put that frame in.

Hi I just see that the mtu in lo is different from standard eth 1500 Any meaning of it? eg: Standard eth 1500 in linux. lo mtu 16436 in solaris. lo mtu is 8232 How about cisco / juniper loopback? Thank you so much
