mam problem z moim routerem ASR-1001x (wersja z 8GB RAM). Router ma 2 sąsiedztwa. Jedno iBGP i drugie eBGP. W każdym z nich dostaje pełna tablice. Do tego momentu wszystko działa prawidłowo. Problem zaczyna się wtedy, kiedy próbuje dodać kolejnego sąsiada eBGP.

próbowałem na 2 wersjach softu rekomendowanych przez Cisco. Miał ktoś może coś podobnego?
