Potwierdzam. 7.7.7.7 nie ma FS. Gdy router traci lacznosc z successorem, trasa przechodzi w tryb active. Mimo wszystko MTU nie jest brane pod uwage - wygrywa pierwsza, ktora otrzyma router.gumisb pisze:Debug eigrp fsm (siec docelowa 10.5.5.0/24 niedostępna idzie w activ, następnie dostępna i trasy w kolejności zgłoszeń)
