Hmm, I'd swear there was a defined minimum, I may have the wrong one. For reference, it appears Cisco IOS based devices won't allow MTU smaller than 128 to be configured. I have no idea if that's based on some standard. It seems like there should be a minimum global standard. -- Leo Bicknell - bicknell@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ Read TMBG List - tmbg-list-request@tmbg.org, www.tmbg.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
