...podczas labowania napotkałem na problem związany z auto-summary. Zacznijmy od tego, że labuje na RIP-v2 ponieważ jako protokół bezklasowy ma możliwość wyłączenia automatycznego podsumowania tras. A więc do rzeczy, czy po włączeniu auto-summary na routerze powinien podsumować mi trasy (na tym właśnie routerze) do granic klasowych, czy rozsyła on tylko podsumowane trasy i dopiero router sąsiedni widzi trasę po podsumowaniu? Topologia R1 --- R2 --- R3. R2 natomiast prawidłowo podsumował trasy 10.0.0.0/8 i 192.168.2.0/24.
Przykład z mojego routerka labowego R1:
