Добро пожаловать в блог! Надеемся, что Вы еще вернетесь.
Один из наших читателей (пожелавший остаться анонимом) прислал нам по мылу конфигурацию для схемы с Juniper MX80, в которой прокидывается vlan через trunk проходящий через 80тые Juniper`ы.
Спасибо ему за инфу, т.к. она точно будет полезна всем кто столкнется с подобной задачей.
