- Purple, 4500 points or more
I've had another question asked that I don't know the answer for. I have two sites connected point-to-point. They are on separate subnets: 10.1.2.0 / 10.1.102.0. The 10.1.102.0 network gets dhcp addresses from the 10.1.2.0 side. I've been asked to flatten the network that would allow all addresses to be on the 10.1.2.0/24 subnet.
I think I need to create VLANs for both sides. I'm not sure where to start, but I think I need to rip the address off of the fa0/0 interface for the 10.1.2.0 network, and create subinterfaces on fa0/0 like fa0/0.3. I would then attach it to VLAN 3, and do the same for the other side. Now, what happens to VLAN 1 on the 10.1.2.0 side? I can't just keep the VLAN 1 without an address, can I? Will clients on the 10.1.2.0 side be able to connect to the router at all if there's not a VLAN 1? Can I just have the VLAN 3 listed in the router and be okay?
Maybe this falls under campus VLANs, but I've never done it before.
