MTU 576

iye · Непрочитанное сообщение **iye** » 2009-03-15 15:06:27

Приветствую!
Имеется mpd4. В конфиге написано:

set link mtu 1472
        set link mru 1472

Но почему то при поднятии соединения на интерфейсе вижу:

Код: Выделить всё

ng0: flags=88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> metric 0 mtu 576
        inet xx.xx.xx.xx --> xx.xx.xx.xy netmask 0xffffffff

Откуда это берется ? Заранее благодарен за ответы.

Я может чего не понимаю... но в доке написано что без этой настройки на одном бандле будет запускаться тока 1 линк .. нет ?

Разобрался. Проблема была в настройках радиуса, а именно в файлах attrs и users. Указал Framed-MTU >= 1472, и все взлетело.
