Hello all lovers Mikrotik

in ether 1 have address 10.10.10.0/24
in ether 2 have address 20.20.20.0/24
in ether 3 have address 30.30.30.0/24


Now ether 1&2&3 having ip address and DHCP for 3 ether

when i connected pc 1 from ether 1 , and take dhcp from 10.10.10.0/24
and connected pc 2 from ether 2 , and take dhcp from 20.20.20.0/24
and pc 3 from ether 3 and take dhcp from 30.30.30.0/24

Required , when i ping from pc1 to ip (pc2) , don’t have replay from cmd
The same thing in the case of ether 3

why ?
What we do in order to be linked for all ethers connect to gather ?

Hi

You will have to setup ip routing to tell eth1/2/3 what to do with a ip that is not in it’s range.

can you Explain your idea by picture

When presenting a problem, you should provide the configuration in use. In your case you should show us the output from /ip export

Also, on your PCs that you expect to ping eachother, show the IP configuration (in a command prompt, use /ipconfig all)
