I have a router with two fastethernet interfaces f0/0 f0/1.f0/0 does not have any subinterfaces and has only one ip address 10.0.1.x/24.F0/1 on the other hand has several Vlans on subinterfaces(etc 10.0.2.x/24). The f0/0 is connected with a switch A. The link is not a trunk link. The f0/1 is connected with the same switch. The link is a trunk link.
1. For users to at 10.0.2.x/24 to connect to users or Servers on net10.0.1.x/24, the link between f0/0 and Switch must be a trunk link or not?
2. The strange thing is that at 10.0.1.x/24 there is a Server. Users at 10.0.2.x/24 can run the program at this Server, can ping other users at 10.0.1.x/24 but they can not connect for share files at that net. Why is that?(No firewall is on)
