Cześć.
Co miałbym poprawić?
Moja topologia:
https://ibb.co/qsLH4Ln

R1
Router(config-if)#do show ip int brief
Interface IP-Address OK? Method Status Protocol
GigabitEthernet0/0/0 10.0.0.1 YES manual up up
GigabitEthernet0/0/1 192.168.1.1 YES manual up up
Tunnel1 50.50.50.1 YES manual up down
Vlan1 unassigned YES unset administratively down down
tutaj dlaczego Tunnel 1 mam protocol DOWN? (pewnie przez to nie mam pinga z jednego kompa do drugiego)

r3
Router>show ip interface brief
Interface IP-Address OK? Method Status Protocol
GigabitEthernet0/0/0 20.0.0.1 YES manual up up
GigabitEthernet0/0/1 192.168.2.1 YES manual up up
Tunnel1 50.50.50.2 YES manual up down
Vlan1 unassigned YES unset administratively down down

Pokaż konfigurację tuneli, bo teraz to wróżenie z fusów.

na router R2 nie konfigurowalem tunelu

Oba routery mają do siebie trasy?

Dodałem
Na r1 i r3
Trasy 0.0.0.0 0.0.0.0 gig ethernet 0/0/0
Zadziała lo bez tego nie...
Czemu to tak?
Wcześniej dodałem jedynie trasy tunelu gre do r1 i r3

Potrzebujesz jedynie trasę:
z R1 do R3 -> 20.0.0.0 255.255.255.0 giga 0/0/0
z R3 do R1 -> 10.0.0.0 255.255.255.0 giga 0/0/0

Być może za szybko sprawdzałeś i nie było jeszcze trasy w tablicy routingu.
