Can different subnets use the same switch?

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 devices on different subnets communicate?

Devices in different subnets can communicate. That is the purpose of a router. Routers route packets between different networks. Even if devices in different networks are on the same layer-2 broadcast domain, you need a router to let the devices communicate at layer-3.

Can two different network be connected to the same switch?

If you mean you have 2 hosts connected to a switch and you have set their IP addresses to be on different networks, they won’t communicate. This frame is presumably picked by all the hosts, even the ones on the other network (192.168. 2.0/24) since they have same broadcast address.

How can I connect two different subnets?

How to Connect Computers That Are on 2 Different Subnets

  1. Connect the computers to the network.
  2. Connect the routers to each other.
  3. Enable a routing protocol in each subnet’s router.
  4. Allow time for the routing tables to update.

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.

How do different subnets communicate?

To get the subnets to talk to each other, you need to set the gateway address on each router to the other subnets server address, Why are you running multiple networks without routers to protect them?

How do you connect different subnets?

How to connect two different subnets

  1. Connect the Server and both Computers to a Layer 3 switch.
  2. Put Server and Computers on same VLAN and enable VLAN trunking.

Can I have 2 networks on the same router?

Yes, it is possible to use two (or even more than two) routers on the same home network. The benefits of a two-router network include: A second router provides more open Ethernet ports so that additional computers can join the network.

What is VLAN in CCNA?

VLANs (Virtual LANs) are logical grouping of devices in the same broadcast domain. VLANs are usually configured on switches by placing some interfaces into one broadcast domain and some interfaces into another. Each VLAN acts as a subgroup of the switch ports in an Ethernet LAN.

Do switches connect subnets?

ONLY ROUTERS CONNECT TWO DIFFERENT SUBNETS, SWITCHES DON’T. So, if two subnets are both connected to a router, they do share the same gateway, which happens to be the router. That’s how they go out.

Can a subnet have multiple VLANs?

No, VLANs don’t require different subnets. Different subnets require different subnet addresses if they ever need to be able to route and/or talk to each other) and by extension if one VLAN wants to talk to a different VLAN it must use different addresses so we can make a routing decision to the right place.

Can two subnets share the same Gateway Interface?

A gateway is LAN device’s way out of its local network. If two subnets or vlans are connected to the same switch, they most definitely can share the same physical exit (router interface) out of the network but because a gateway is defined by its IP address making it unique to a subnet,…

Can two devices share the same IP address on different switches?

Short answer no, but it depends on your definition of ”share”, it doesn’t matter if they are on the same switch or on different switches but IP address and gateway MUST be on the same subnet. Let’s make an example: Device A: Here 192.168.1.10 and 192.168.1.1 are on the same subnet.

What happens when two hosts are in the same subnet?

So, when two hosts are in the same IP subnet but on different VLANs/broadcast domains/L2 networks, they can’t communicate: the source host assumes the destination in within its local L2 network and therefore it tries to ARP the destination address (or NDP resolve for IPv6).

Can two computers in the same subnet be connected directly?

Conventionally the computers in the same subnet are connected directly and most of the times, do not go through the gateway. To explain it more clearly, If you’re on a Linux machine, run route -n. The first entry has a destination ranging from 14.0.1.0 to 14.0.1.255.
