Есть 2 управляемых коммутатора DES-3828. Между ними отдельный VLAN. Задача - моментальное включение в группу и быстрый выход из нее.
Никак не разберусь с заданием времени в протоколе IGMP и PIM (DM), а также какие параметры по времени необходимо задавать в IGMP Snooping?
При таком конфиге - все работает быстро и хорошо, но не считаю это правильным. Поправьте меня где это нужно. Конфиг второго коммутатора идентичен. Сервер видеовещания подключается к одному из этих.
Вот мой конфиг.

Вы не могли бы перезвонить завтра во второй половине дня в офис по телефону 744-00-99 доб.390?

К сожалению, не имею возможности (выход на межгород закрыт).

Вы просто подскажите каковы должны быть тайминги в IGMP и PIM для практически мгновенного получения картинки.
К этим 2м свитчам будут подключены еще свитчи 2го уровня и только к ним пользователи.

Это параметры которые для каждой сети надо подбирать. Удобнее было бы пообщаться. Укажите Ваш телефон если это возможно.
