Добрый день. Существует сеть предприятия состоящая из нескольких Vlan завязаных через SVI на Cisco 3550(ip routing). 3550 опять же через SVI связана с 7206(настроен int gi0/0.5 с одинаковым номером Vlan), а 7206 по сериальным портам соединена с двумя десятками 2650. Протокол маршрутизации EIGRP. Необходимо перевести все на OSPF. С 7206 и 2650 нет проблем подымаеш OSPF параллельно. А на Cisco 3550(OSPF и EIGRP) сети с 7206 по OSPF не приходят.Хотя если проверить соседние OSPF 7206 видно. Никаких access-lists и других настроек безопастности для маршрутизации нет, сети передавемые через EIGRP не пересекаются с OSPF, все тесты проводились для area 0(для всей сети), версия IOS на 3550 подходящая. Подоскажите в чем может быть проблема ???
