Friends Greetings
I’m a problem in part of network that attached file will explain
I Routing networks with OSPF, I am using version 3.20 or 5.18 of Mikrotik use the ospf settings here
- At present all computers (c1, c2, c3, c4) are easily connected to the internet and do not have a problem.
- computers C4 easily see c1, c2, c3 (ping, and connect OK) and have no problem
- this computer (c4) see c1, c2, c3 and ok
But the problem:
The problem is that computers c1, c2, c3, they should not see each other, even computers, c2, c3 are both connected to a router
- No firewall and no rule on None of the routers have not defined
- Clients like c1, c2, c3, c4 get IP from DHCP and I sure are correct
- All computers can see target router (ping and Trace) all interfaces (ping the Gateway Destination PC)
Also I am sure that reverse route is Ok and (it was created on the router dynamicly)
