Can VLANs have different gateways?
Your best bet would be to avoid creating a layer 3 interface on the Dell switch for the VLANs that need a different default gateway. Then you can use another router, connected to the Dell switch with a VLAN trunk port, to provide routing for those VLANs as a “router on a stick”.
What is the gateway for a VLAN?
A default gateway is always in the same subnet as the IP address of an interface. Default gateways are used to get out of your local subnet, so if it wouldn’t be in the same subnet, a computer doesn’t know how to reach the subnet. So, for the default vlan to go through FW02, it’s default gateway would be 10.1.
Does each VLAN need its own default gateway?
on the same vLan they should not need a default gateway, if you wanted to ping say from 192.168. 3.100 to 192.168. 5.100 you would need to set the default gateway as the core/L3 switch.
How do I change the default gateway on a VLAN?
To configure the default gateway for the switch, use the ip default-gateway command. Enter the IP address of the default gateway. The default gateway is the IP address of the router interface to which the switch is connected. Use the copy running-config startup-config command to back up your configuration.
Do VLANs have to have different IP addresses?
VLANs do not really have IP addresses assigned to them. They have a network assigned to them, or a subnet, or a network range, however you want to refer to it.
What is a VLAN Cisco?
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.
Can two VLANs have the same IP address?
Yes. A vlan is nothing more than a virtual switch so is completely ambivalent to the IPs running on top of it. The dead giveaway is that vlans are a layer 2 technology and IP addresses are layer 3. Easiest test is setup multiple vlans on a switch and connect a physical cable between access ports on different vlans.
Can different VLANs be on the same subnet?
1 Answer. Of course you can do that, but it is not the recommended way. VLANs use software to emulate separate physical LANs. Each VLAN is thus a separate broadcast domain and a separate network.
What are the types of VLAN?
Types of Virtual LAN (VLAN)
- Default VLAN – When the switch initially starts up, all switch ports become a member of the default VLAN (generally all switches have default VLAN named as VLAN 1), which makes them all part of the same broadcast domain.
- Data VLAN –
- Voice VLAN –
- Management VLAN –
- Native VLAN –
Which is the default gateway for VLAN 2?
Each vlan must have a different network. You can try this: 1-Use the 192.168.200.0/24 network for vlan 2 2-Assign an IP of the new network to the Vlan 2 PCs, with the correct mask and ip 192.168.200.1 as the gateway.
How to configure two VLANs on the same interface?
Each device on these two VLANs must set the IP address of the default gateway to be the IP address configured for the VLAN. In this example: Devices on VLAN10 must use 192.168.10.1 as their default gateway. Devices on VLAN20 must use 192.168.20.1 as their default gateway. Select Network > Interfaces. Select interface number 3. Click Edit.
When do packets have the same VLAN ID?
Packets are tagged with vlan ID for lan segment only while passing through trunk. over WAN what matters is ip traffic. when a router (layer 3 interface) recieves a VLAN tagged frmae. it strips of all the previous layer 2 info.
How to add a VLAN to a network?
In the Interface Name (Alias) text box type vlan. From the Interface Type drop-down list, select VLAN. Click Save. Select Network > VLAN. Click Add. In the Name text box, type a name for the VLAN. For this example, type VLAN10.
