I have a cisco router 3845 with 16 FastEthernet Ports.
Each Ports are connecting to different networks.
For example those are the networks connected to my interfaces:
E1/0: 10.1.1.0 /24
E1/1: 10.2.1.0 /24
E1/2 192.168.1.0 /24
E1/4 10.20.20.1 / 24
Let's pretend this.
E1/0 needs to communicate with E1/1 and E1/2 but not with the others interfaces
E1/1 needs to communicate with E1/0 and E/1/3 but not with the others interfaces
E1/2 only need to communicate with E1/0 and not with the others interfaces.
My question is how can i configure that on my cisco.
Do I have to create differents vlans for each network and then assigned them to an interfaces?
If yes, how can i add static routes on vlans interfaces?
Thanks a lot for your help
