kirush Posted January 17, 2012 Posted January 17, 2012 (edited) Добрый день! Подскажите в чем может быть проблема. Имеется один роутер (192.168.0.254) а и 2 NAS (192.168.0.252, 192.168.0.251), находятся в одной /24 сети: router 192.168.0.254: hostname ospfd password xxx log file /var/log/ospfd.log ! router ospf ospf router-id 192.168.0.254 network 192.168.0.0/24 area 0.0.0.0 neighbor 192.168.0.252 neighbor 192.168.0.251 ! line vty !

nicolnx Posted January 17, 2012 Posted January 17, 2012 А зачем вы соседей статикой прописываете? OSPF их и сам в состоянии найти (если там не NBMA какой-то) Вставить ник Quote
kirush Posted January 17, 2012 Author Posted January 17, 2012 Ругается то он не на то, что статикой прописал :) Хуже не будет я думаю...исходя из всех изученных мною мануалов, рекомендуют указать соседей именно так. Вставить ник Quote

pliskinsad Posted January 18, 2012 Posted January 18, 2012 Хуже не будет я думаю...исходя из всех изученных мною мануалов, рекомендуют указать соседей именно так. Хуже будет! Статикой нужно прописывать нейборов в только NBMA сетях, или там где не работает мультикаст. Причем во втором случае, мне кажется нужно указывать на интерфейсе тип p2p или pmp. Какая версия кваги?
