Static Route

[sonanh198b@gmailc.om]

% 192.168.3.0 overlaps with FastEthernet0/0Routing, Other Routers

https://www.solarwinds.com/free-tools/advanced-subnet-calculator#subnetcalculator . Does it work any lab?

I am so confused this lab. I do not know how to ping all router, and the end device

Hello

Try the following:

R1
ip route 192.168.23.0 255.255.255.0 eth0/1 192.168.12.2
ip route 192.168.3.0 255.255.255.0 eth0/1 192.168.12.2


R2
ip route 192.168.1.0 255.255.255.0 eth0/0 192.168.12.1
ip route 192.168.3.0 255.255.255.0 eth0/1 192.168.23.3


R3
ip route 192.168.12.0 255.255.255.0 eth0/0 192.168.23.2
ip route 192.168.1.0 255.255.255.0 eth0/0 192.168.23.2

I wonder know the loopback for r1 r3

Hello,

there is no information whatsoever given regarding loopbacks, except for R2. So on R1 and R3, it can be anything. What lab is that, what instructions are you following ?

That said, you could further minimize the amount of static routes by using just default routes on R1 and R3:

R1
ip route 0.0.0.0 0.0.0.0 192.168.12.2


R2
interface Loopback0
ip address 192.168.2.2 255.255.255.0
!
ip route 192.168.1.0 255.255.255.0 192.168.12.1
ip route 192.168.3.0 255.255.255.0 192.168.23.3


R3
ip route 0.0.0.0 0.0.0.0 192.168.23.2

this lab is from the instructor Duy Long. I am learning CCNA from the Vietnamese school. I sometimes confuse some lesson in the class. I ask it. This one will work in the real world

R1
ip route 0.0.0.0 0.0.0.0 192.168.12.2


R2
interface Loopback0
ip address 192.168.2.2 255.255.255.0
!
ip route 192.168.1.0 255.255.255.0 192.168.12.1
ip route 192.168.3.0 255.255.255.0 192.168.23.3


R3
ip route 0.0.0.0 0.0.0.0 192.168.23.2
