Приветствую.
Есть 7206VXR (NPE-300) куда приходит full-bgp от одного апстрима (пока от одного). И все вроде здорово, но где-то раз в минуту загрузка процессора подскакивает до 50-60% (в остальное время колеблется около 10%), BGP Scanner в этот момент показывает 30-40%.
Ситуация в приниципе не критическая, но т.к. планирутся подключение еще одного апстрима с полным получением bgp и небольшого апстрима на 1000-2000 префиксов хотелось бы более плавно распределять нагрузку на процессор по времени.
