Can a switch Connect 2 subnets?

You can use the same switch for multiple subnets, but you need to you VLAN’s that is what they are there for, unless you switch won’t support VLAN’s. First time your switch gets a MAC address back that has an IP addresses in more than one subnet it’s gonna freak out.

Can you route between two subnets?

What you need to do is set up routing between the two subnets. They will remain separate entities, but traffic will be able to flow between them.

Can a router handle multiple subnets?

1) It is possible to have multiple subnets “behind” one router; the Internet would be a very broken place with millions more routers needed if it were not. However, your example of using a /16 subnet mask on the LAN interface, with many /24’s connecting to it, is not exactly how it would actually function.

Can a subnet span multiple switches?

Yes. You don’t even need a trunk. If all ports on both switches are access ports on Vlan 3, then the port connecting the two switches are on Vlan 3 and both switches form one broadcast domain on that Vlan.

Can a router support multiple subnets?

How do I connect two networks together?

All you have to do in the router that connects the two networks it this:

1. Configure each of two Ethernet ports into different VLANs.
2. Assign each VLAN an IP address in one of your two networks.
3. Connect each port to the network that port’s VLAN has an IP address in.
4. Make sure the router is configured to do routing.

Do I need a router between subnets?

You don’t need a router. If you set the subnet mask on all of the PCs to be 255.255. 0.0, then they should all be able to ping each other. Basically, opening up the subnet mask puts all of the PCs on the same subnet, so a router isn’t needed.

Can you ping across subnets?

You should be able to ping either IP on a separate ping operation, without issue, if your PC is aware of where those networks are. If the routes aren’t already there, you should be able to add them yourself.

Can I have 2 subnets on the same network?

*You can have more than just two subnets on a LAN. Cisco refers to them all as secondary addresses although they technically should be called tertiary, quartenary, etc. “Cisco routers would establish OSPF or EIGRP neighbor relationships on secondary addresses.” I think you mean “would not.”

How do I connect multiple subnets to one router?

If you would use only one router, there are two ways to go: Router-on-a-stick (both subnets will use or are connected to the same router interface) or connect each subnet to a different interface (remember each router interface should belong to different subnets).

Is it possible to communicate between two different subnets?

However, you can communicate between subnets with different subnet masks. You just have to have a router with network interfaces on each of those subnets to handle the traffic. Also]

What device do I need to route between the subnets?

You need a layer 3 switch (preferably a Cisco as opposed to the Allied Telesis) or a router in order to route between the subnets. What is the default gateway for your 10.10.1.X devices?

Is the subnet mask for switch B right?

As I pointed out in my first post, the subnet mask for switch B is definitely not right. However, you can communicate between subnets with different subnet masks. You just have to have a router with network interfaces on each of those subnets to handle the traffic.
