Can you have multiple LANs?
When we understand how traffic flows through networks, we can dive into the two main ways to set up multiple LANs on a single router: subnets and virtual local area networks (VLANs). Subnets are the logical groups of addresses that we use to separate networks. A single network can also be subnetted.
Does the router sharing same link belong to same network or different?
The Routers sharing the same link must belong to the same network.
How do I connect multiple LANs?
A bridge can be used to connect two similar LANs, such as two CSMA/CD LANs. A bridge can also be used to connect two closely similar LANs, such as a CSMA/CD LAN and a token ring LAN. The bridge examines the destination address in a frame and either forwards this frame onto the next LAN or does not.
How to have two LANs with one router?
If you have two routers already, then just plug the WAN port of each into your switch, which can be VLAN 1 if you want. Your Comcast modem will hand out private IPs to your routers. As long as you plug in your devices to the appropriate router (Netgear and Belkin) then you have two LANs
It may technically work, but it’s not a great idea. The two networks will share a single broadcast domain. In practice, this can cause very strange, hard to diagnose issues in some applications. It would be much better to get a second unmanaged switch or spring for a cheap managed switch.
When do you need two separate internet connections?
There are times when having two separate networks – both sharing the same Internet connection – can come in handy. For example, I recently helped a community center with its network setup. They needed to provide Internet connection to tenants who were renting space, in addition to their own shared Internet.
Do you need a managed switch for a home router?
(For a home, or a small office, an unmanaged switch is fine. If you really want total control over traffic, channels, etc.,you’ll need a managed switch, but they’re more expensive.
