Имеются два роутёра (конфиги ниже) между ними бегает ospf. Проблема в том , что при поднятии BGP(Comstar) на R2 , на R1 перестаёт трафик литься на Golden и на R2 по нулям.
ПО ibgp на R2 маршруты от R1 отдаются . Проверить на рабоче сети с долгим разберательнством невозможны (расстреляют). Буду благодарен за любую помощь!
