Здравствуйте, товарищи!
Имеется Cisco 7206 NPE-G2, выполняет роль пограничного маршрутизатора на Интернет, также на нем работает NAT и BGP. На данный момент маршрутизирует порядка 140 Мегабит/с на входящий, и 50 Мегабит/с на исходящий и при этом загрузка процессора 85%/65% (65% по прерываниям). Помогите идеями :), цисковскую документацию по борьбе с перегрузками изучил но пока что глухо. Если эту тему увидят владельцы 7206 NPE-G2 отпишите пожалуйста сюда какой объем трафика она у вас маршрутизирует и какие сервисы при этом провайдит. Читал что у одного админа 7206 NPE-G2 500 Мегабит маршрутизировало и он был не доволен, а у меня только 140, представляете как недоволен я?!))Приведу немного информации для анализа:
