What is overlapping VLAN?
A VLAN is an administratively configured LAN segment that limits the traffic in multiple broadcast domains. Instead of physically reconnecting a device to a different LAN, network administrators can accomplish this task by configuring a VLAN compliant switch to create logical network segments.
Can you have 2 VLANs on the same subnet?
If the addresses are all different it is possible to route traffic using a very large number of rules which don’t correspond to the actual subnet configuration and will confuse anyone who inherits this from you. However, it is completely permissible to use the same RFC1918 subnets on different physical networks.
What is an overlapping network?
An overlapping network (subnet) is when you establish a connection from the VPN client to another network with the same ‘private IP address range’, and an ‘overlap’ occurs with the addresses. When the client connects, it uses the source IP address it currently has, which is the home network.
Can A Faste interface overlap with a VLAN?
Your fastE interface and software interfaces such as Vlan 1,2,3 etc all are individual interfaces to the router’s software. So it wont allow any set of overlapping between the subnets. If 10.10.10.X has been assigned to fastE interface, you cannot assign an address to any other interface of the same router.
Can a router over lap on more than one interface?
Re: VLAN Overlapping – Don’t Get it. Note that a router does not allow ip addresses to over lap on more than one interface. Your fastE interface and software interfaces such as Vlan 1,2,3 etc all are individual interfaces to the router’s software. So it wont allow any set of overlapping between the subnets.
Which is the wrong subnetmask for VLAN 10?
03-01-2019 10:04 AM interface vlan 10 on the host HQ has the wrong subnetmask. This means the subnet is from 192.168.3.0-127 and therefor it overlaps with the ip you try to configure on VLAN20. Change the ip addres on vlan 10 to 192.168.3.1 255.255.255.192 should do the trick.
How many subnets are there in VLAN 3?
Now you have three subnets 10.10.10.0, 10.10.20.0 and 10.10.30.0. The second subnet is tied to fa0/1 (the port fa0/1 has been made a layer 3 port using “no switchport” command) The third subnet is tied to fa0/2,3 and 4 using a Layer 3 SVI interface (Vlan 3).
