Próbuję ustawić sąsiedztwo EIGRP pomiędzy dwoma routerami CISCO (2921 i C8200L).
Routery połączone się jednym interfejsem w podsieci 172.16.172.0/22 i mają końcówki odpowiednio .1 i .2.
Oto skrócona konfiguracja routera 2921:
Kod: Zaznacz cały
interface GigabitEthernet0/0
ip address 172.16.172.1 255.255.252.0
no ip proxy-arp

Na pierwszym routerze dostaję komunikaty:

Może ktoś ma pomysł, co robię nie tak, że routery nie widzą sąsiedztwa EIGRP?
