IP Addresses ranging from 192.168. 0.0 to 192.168. 255.255 are Class C private IP Addresses, which aren't routable to the Internet. That said, if they're are on the same LAN, they're normally capable to talk to each other, unless there's some cable problem.
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.
Each VLAN will typically correspond to its own IP Network. In the same way, a Router is what we will need in order for hosts in different VLANs to communicate with one another. There are three options available in order to enable routing between the VLANs: Router with a Separate Physical Interface in each VLAN.
A subnet mask is a number that defines a range of IP addresses available within a network. A single subnet mask limits the number of valid IPs for a specific network. Systems within the same subnet can communicate directly with each other, while systems on different subnets must communicate through a router.
A Subnet Mask defines which range of IP Addresses are within a local network, and which ones are not. Subnet masks always work from left to right. Devices are said to be within the same subnet if their IP Address starts with the same digits, but ends with a different set of digits.
To calculate the IP Address Subnet you need to perform a bit-wise AND operation (1+1=1, 1+0 or 0+1 =0, 0+0=0) on the host IP address and subnet mask. The result is the subnet address in which the host is situated.
Well you can't, not on a Cisco router. You cannot have two overlapping networks on two different layer 3 interfaces. Otherwise the router could not decide on which interface it must send a packet for this network. This is why your dual gateway cannot work.
It is possible to use a second router as a range extender to your existing network. It is also very possible to create only one network name between the two routers so your BluOS Players and other network devices will connect to which ever router has the stronger signal.
The OSA-Express Layer 2 implementation allows the hosts to manage IP addresses and ARP cache, so it is possible to have a single guest LAN segment (or VSWITCH segment) where two different hosts use the same IP Address on different VLAN groups.
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.
A VLAN is an Ethernet level concept, a subnet is an IP level concept. A VLAN splits an Ethernet network into multiple logically seperate Ethernet networks. A subnet defines which hosts a host will try to communicate with directly verses which hosts will need to go via a router.
If there is no configured default route/gateway, then a ping will fail with a "no route to host" error. In a little more detail, PC1 will compare the destination address to it's local subnet, which is calculated from the IP address and subnet mask. If there is no route, it will not send the traffic and return an error.
If your switch has L3 ability, you can issue the ip routing on the global config and then use the ping. Also the L3 communication between VLAN interfaces (as known as SVI on Cisco literature) starts to work. This test can be done either on the switch itself or by the hosts which are connected to their respective VLANs.
Under IEEE 802.1Q, the maximum number of VLANs on a given Ethernet network is 4,094 (4,096 values provided by the 12-bit VID field minus reserved values at each end of the range, 0 and 4,095).
A unmanaged switch does not have an IP address. It is a ethernet switch and it switches ethernet packets and on the level of ethernet packets there are no IP addresses. The switch is only the mean to connect three or more devices.
VLAN is based on Layer 2 “Data link” of the OSI Model. The OSI layers are independent of each other and they communicate with each other. If any one of the layer gets compromised the other layers also fail. The VLAN is on the Data Link layer, which is as vulnerable to attacks as any other layer on the OSI model.
5: A VLAN is always associated with only one subnet. IT folks often talk about VLANs in terms of subnets. For example, if a server has an IP address of 192.168.
