Hi there,
I’ve got this situation:

I’m on Router A and I want to ping Router B.
Which static route I have to insert on all routers?
I’ve made a couple of configurations but I can communicate only between A and B - B and C. A can’t ping C.
Can somebody kindly help me?
Which router is closest to the internet?
If A, then:
- RouterA:
/ip route add dst-address=192.168.100.0/24 gateway=192.168.1.1
RouterB:
/ip route add gateway=192.168.1.2
RouterC:
/ip route add gateway=192.168.100.1
If B, then:
- RouterA:
/ip route add gateway=192.168.1.1
RouterC:
/ip route add gateway=192.168.100.1
If C, then:
- RouterA:
/ip route add gateway=192.168.1.1
RouterB:
/ip route add gateway=192.168.100.2
RouterC:
/ip route add dst-address=192.168.1.0/24 gateway=192.168.100.1
If you want to ignore the question about which is closest to the internet, you can skip the use of default routes and just add the following routes by themselves:
- RouterA:
/ip route add dst-address=192.168.100.0/24 gateway=192.168.1.1
RouterC:
/ip route add dst-address=192.168.1.0/24 gateway=192.168.100.1
